The Honest Money Show

What happens to your Bitcoin if you get hit by a bus tomorrow, and could your family actually access it, or would it be lost forever?

Mike, product manager at Guardblock, joins Honest Money to tackle the hardest problems in Bitcoin self-custody: backups, inheritance, and staying secure in a world where AI is making attacks more sophisticated by the day. In the wake of the Coldcard hack, Mike explains why a single device is no longer good enough, how collaborative security using multisig and Bitcoin timelocks works, and how to make sure your coins reach your heirs without leaving a dangerous security hole.

🎙️ EPISODE SUMMARY

Mike and Anja discuss self-custody, collaborative security, and Bitcoin inheritance.

The conversation moves from the lessons of the Coldcard hack and recent data breaches, through the difference between custodial and non-custodial, single-sig and multisig, to how Guardblock's time-locked vaults add a co-signing key and recovery pathways without taking custody of your coins. Mike explains why self-custody still demands personal responsibility, how timelocks let you exit unilaterally if the company disappears, and why inheritance is the single biggest reason people are signing up.

The episode also covers wills and letters of wishes, the privacy and trust trade-offs of collaborative security, which hardware wallets work with Taproot miniscript, the product's pricing, and why everyday people shouldn't need to be technical experts to keep their Bitcoin safe.

Whether you're brand new to these questions or already deep in them, you're welcome here.

Since the Coldcard hack,

I've always had a low grade anxiety about my self-custody.

Did I do a right? Did I miss a step?

And I always go back and check it and make sure

like I do a health check every three months

, um, on my self-custody, but still like

my low level anxiety is now medium level anxiety.

Their inheritors find their backup, their seed backup,

And they are like like, Oh, I know this can get Bitcoin.

Only need to get access to this Bitcoin.

And then they contact some random person online

because they don't know what to do.

And they say, okay, help, help me out.

Here's the seed words. And then the attacker goes

, oh, goody, goody, goody. Um. thank you

for the free Bitcoin!

So, there's been a lot of relief

because particularly cos of in light of the Coldcard incident

which we've touched a few times.

there's been a lot of people thinking - 'What can I do?

Nothing is safe. I'm, I'm scared!'

Welcome back to another

episode of Honest Money. Joining me today

is Mike. Mike is the product manager from

GuardBlock. Welcome to the show, Mike.

Howdy, Anja. How are you going? Really

good, thanks. I'm really happy to have you

on because I've had a number of inquiries

from the locals here in Northern Rivers

where I live. They are wanting to know a

little bit more about this product, which

is newly launched to the Australian

market. But I also wanted to talk about

self-custody a little bit. And the reason

is because obviously we've had the recent

Coldcard hack, which was a devastating

blow to the confidence of many people in

our community. And then we've also had a

number of data breaches. There was some

issue with BTC Pay Server. There was

another issue with the Blockstream Liquid

Network. So there's quite a few things

happening. Let's maybe start with what

have we learned in light of those events

about self-custody? Yeah. So it's

definitely, as you say, it's been a bit of

a rough month or two in the Bitcoin space.

And what we've learned is these AI tools

that are out there are very sophisticated

and they're improving every day. And so

we're learning a lot of lessons about all

businesses, all products, all open source

repositories and everything. They're a lot

more vulnerable because they are just out

there. It's a very juicy target for

attackers that are getting their hands on

these sophisticated tools to dig into them

and have a go and see what they can do. So

what we're learning as an industry and as

the Bitcoin network is that we need to do

more. We need to do better in regards to

checking and testing and attacking our own

tools, especially with the help of these

AI tools. So using them ourselves to make

sure that all of our products and services

are up to scratch. And so, yeah, we're in

a bit of an interesting phase worldwide. I

think we're going to start to see it in

Bitcoin and then we're going to start to

see more breaches and attacks happen in

the rest of the world, the rest of

industries that are out there. But Bitcoin

is kind of first off the chopping block

because it is this globally accessible

network that anyone can jump on. Anyone

can look at these open source repositories

and have a go and have a crack with these

AI tools and try and attack them. So the

lesson learned is we need to just be doing

better using these tools ourselves and

finding these holes and plugging them

before an attacker exploits them. Do you

think it is an attack on self-custody? Do

you think it's going to change the way

people approach it? I mean, it's already

hard to begin with, but I feel like is

this another layer of just making it even

harder for newcomers? There are a lot of,

I've been having a lot of interesting

conversations around this. There's a lot

of, you know, tinfoil hat theories that

maybe this is a coordinated attack on self

-custody and they want to scare people

away from taking self-custody of their

Bitcoin so that the industry, the sort of

dinosaurs of the older industries can

maintain a status quo in the new world.

You know, don't do it yourself. Trust the

institutions, trust the businesses, trust

the banks to store your Bitcoin, to store

your wealth for you. So there is a theory

that it is some sort of coordinated attack

to scare people away from the new paradigm

of taking that full self-custody and that

full sovereignty of your money and your

wealth. I'm always a big, big fan of

conspiracy theories and sort of out there

theories. I don't necessarily think it's

the case. I think it is just the fact that

Bitcoin's a juicy target. These tools are

out there. They're very easy for people to

jump on and start using them to attack

these open source tools and other projects

that are out there. And the reward is

great. So the incentives are all there for

attackers to do what attackers do. I don't

think it's a coordinated attack at the end

of the day. And in regards to scaring

people away from self-custody, absolutely,

we do see that. We do see a lot of people

doubting themselves and doubting the tools

around maintaining their self-custody and

sovereignty themselves without some extra

help. And that's why, you know, you need

to do your research and you need to find

where is the happy medium for you. There

is still the absolute, you know, way that

you can fully do it yourself and you can

do it safely. There just have been these

unfortunate vulnerabilities, which the

bare minimum of self-custody,

unfortunately, you might've been wrapped

up in some of these attacks. So it does

show that if you are going to take that

step of doing it yourself, fully self

-custody, fully sovereign, you do really

need to do your research and make sure you

are going not just, you know, the bare

minimum. You need to be doing a few steps

forward, not the absolute maximum, you

know, hyper-autism sense, but more than

the bare minimum, because then you are

protected from a single point of failure,

a single vulnerability, a single issue in

a single project or a single device or a

single something that you're using. You

need to add at least another layer or two

onto your ladder. Yeah. Yeah. So would you

agree that the bare minimum today or prior

to the Coldcard hack may have been just,

you know, you buy a hardware wallet of

your choice. You don't even do necessarily

a lot of research into what kind of

wallets you're using. Some people are

using, you know, wallets that support

multiple coins. Some are Bitcoin only.

Some are open source. Some are closed

source. Some are air-gapped. Some are not.

And people prior to the cold card hack

maybe didn't appreciate some of the things

that I guess the stronger Bitcoin

maximalists have been advocating for a

long time now, and that is to generate

your own seed phrase, like never use the

wallet generator, like do it yourself. And

now I feel like perhaps maybe what some of

the things that have happened, it's raised

the standard of self-custody. We're

looking to add passphrases. We're looking

towards multi-signature solutions. And

it's also helped people essentially look

at other solutions like collaborative

security models and even maybe in some

sense custodial products, at least for a

percentage of their stash because it's

more about diversification than anything

else. Do you feel that's directionally

right? Absolutely. Absolutely. It has

highlighted almost a failure of Bitcoiners

themselves in that when if you're a

Bitcoiner and you do the research, you

spend a thousand hours looking at the

stuff, listening to podcasts, doing all

these sorts of things, and you understand

the risks and the trade-offs. But then

when your trusted friend and family come

to you asking for Bitcoin advice because

you're the Bitcoiner in their life and you

just don't have the time, you don't have

the energy to sit them down. And maybe

they also don't have the time and energy

to equally meet you where you want to meet

them or you should meet them. And so a lot

of people had that minimum assumption of

as long as I get them to get the right

device, they're fine. And just follow the

basic setup for that one device, they're

fine. And up until the Coldcard hack,

that did appear to be the case. Right up

until the Coldcard hack, there was no

real precedent for this sort of thing on

such a scale happening before. All the

failures were due to mistakes by the user

themselves. There were data breaches,

there was this, that, and the other thing.

But there was nothing that kind of scared

people away from just instructing people

to follow that basic one of go and get

your one device, trusted device, set it

up, move your funds there, good enough,

good enough. And while internally you

might be doing the extra stuff, you might

be setting your passphrase, setting up a

multi-sig, doing some extra steps there,

but you may not have passed that

information on to a third party who was

asking for advice. So you just say, go and

get your one device and you'll be fine.

Unfortunately, it's those people that got

smashed with the Coldcard thing. And so

that's why the new, the learning is, if

you are going to take responsibility and

help someone else elevate their Bitcoin

security, you do need to do your due

diligence and say, sorry, just getting a

single device and setting up with the

basics is not good enough anymore. It does

need to have some extra steps. And so as a

Bitcoin, you need to be thinking, well, is

this person that I'm helping, do they have

the time, energy, wherewithal, technical

ability to actually sit down and

understand those extra steps? If yes, then

go for it. Help them, help them become

fully self-custodial, fully self

-sovereign, but they need to do the work.

Alternatively, if you don't have that time

and they don't have the time, then that's

where a custodial situation or a

collaborative security situation might be

more preferable for that person. So you've

got to sort of judge it based on who's

asking for help.

Yeah. And for any

newcomers that are coming in and listening

to these terminology, like how would you

describe custodial versus non-custodial?

So the real basic way to frame it is if

you control the keys to the wallet in

question. So a custodial, an example of a

custodian or a custodial arrangement would

be you have your Bitcoin held on an

exchange. You've just bought it from hard

block or coin jar, whatever, whatever

exchange you use. You have an account

login, but you don't have a key. You don't

have the actual private key associated

with the Bitcoin wallet. So that Bitcoin

wallet is custodial because a custodian,

in this case, the exchange is looking

after that Bitcoin wallet for you. They

are holding the keys for that Bitcoin. So

a hardcore Bitcoin will say, that's not

your Bitcoin. It's an IOU. You have an

account with them and under normal

business, you know, jurisprudence and

contracts, that Bitcoin is technically

legally yours, but physically, physically

in the digital, digital sense of the word,

uh. Bitcoin is held by or owned by that

custodian. So self-custody is when you

move the Bitcoin or you hold the Bitcoin

in your own Bitcoin wallet where you

control the private key, the private key

that actually denotes the spendability of

those coins. So there's a lot of, there's

a little bit of nuance here and there, but

we'll keep it, we'll keep it basic. Yeah.

And there's obviously like new products

coming into the market that are kind of

somewhere in the middle. And I guess we're

going to talk about that a little bit

today. But do you also want to define for

the users, because it's going to set the

context for the remainder of the

conversation or what the difference is

between single SIG and multi SIG? Sure. So

single SIG basically means that you've got

a Bitcoin wallet where in order to spend

that Bitcoin, you sign a transaction and

you only need to sign that transaction

with a single key. So your Bitcoin wallet

was established and it's only looking for

a signature from a single key. And that

single key could be held on a device. It

could be a monomic, monomic, monomic,

always struggle to pronounce that word.

That's the only thing that's needed to

spend the Bitcoin held in that single SIG

wallet. Now, a multi SIG wallet obviously

just extends that. So the wallet is

looking for multiple signatures before it

will broadcast that transaction and it

will be accepted on the Bitcoin network

and it will actually move funds. So a

typical setup might be a two of three. So

two of three means you need two keys out

of a possible three keys in the wallet to

actually send Bitcoin. So you might have

three hardware devices. Each hardware

device has been used to generate a key. So

you've got three private keys. Then you

use that to register a multi SIG wallet.

So you're creating your multi SIG wallet.

And then if you ever wanted to sign a

transaction and move Bitcoin, you need to

get out two of those keys to sign that

transaction because it's a minimum two

signatures out of a three potential keys

in a multi SIG wallet in order to move

funds. And then you can then customize it

from there. You can have 10 keys. You can

have five keys. You can have a one of

five. You can have two of five. You can

have a 10 of 10. You know, it's up to you.

But obviously you always need to remember

that more complexity means more things

could go wrong. It's more things to keep

track of. It's more backups to keep track

of. So you need to, you can't just go,

well, I'm going to go for 50 keys and I

need 40 keys to sign it. Like that's,

that's ridiculous really. Um, at least for

individuals, businesses, it's a bit

different governments. It's a bit

different, but from an individual level,

you want to keep that simplicity factor so

that you're not overcomplicating your

setup. And end of the day, a lot more

Bitcoin has probably been lost due to just

simple mistakes rather than actual, uh,

vulnerabilities and hacks and, uh, and,

and, and that sort of thing. So simplicity

is key. You need to find the right balance

for your situation. Yeah. I think that's a

really important point to make because

backing up your key is like as important,

if not more important than generating or

definitely more important than generating

in the first place, because if you don't

have that backup or you don't remember

where you stored it, it's obviously your

Bitcoin is, is gone. So I think the other

important thing to mention about multi

-signature versus single signature is that

multi-signature removes that single point

of failure. So in a single SIG scenario,

you back up your single signature key. If

something happens to that, it gets, I

don't know, lost in a fire, a flood. Uh,

you forgot where you put it. It's somehow

damaged. Basically, um, your Bitcoin is

gone. Whereas in a multi-signature, for

example, a two out of three, what happens

is you can have your keys in different

locations and you just need two, two out

of the key, three keys, any combination of

two to unlock your, um, Bitcoin. So I

think, yeah, I think a lot of people are

starting to really look at multi-sig as a

favorable solution, but it does obviously

come with a huge technical, um, learning

curve. So let's get into Guardblock.

this solution is. Sure. So Guardblock,

it's a new product. It's built by the team

behind hard block, uh, which is

Australia's longest running Bitcoin only

exchange, uh, operating since 2014. We

built Guardblock because we wanted to

solve a problem for ourselves, which was,

well, how do we make sure if we're, if

we're running an exchange and we're also

holding Bitcoin ourselves for our

personal, personal, uh, sovereign wealth

accumulation, how do we make sure it is

protected from the absolute worst case

scenarios that can happen out there?

Hopefully never happened, but there's

always that potential. And a lot of

Bitcoin is, are always carrying this

mental burden of what if, what if, what

if, uh, for their particular setup. And

everyone's a little bit different.

Everyone's got different risk profiles and

it changes as you start to accumulate

more, as you start to have children and

dependence and you think about inheritance

or you're running a business and you have

a Bitcoin treasury, all these sorts of

things will increase that mental burden.

And so having things like backups and

safety nets, uh, to catch you, if

something does go wrong, uh, the, you

know, these worst case scenarios happen,

it does help to reduce that mental burden

because that's ultimately what Bitcoin

should be. Bitcoin is all about, I can

store my wealth in this thing. The

government can't touch it. Attackers can't

touch it. It's not getting inflated away

and I can get on with my life. But if

you're then having to constantly have this

upkeep of storage and devices and backups

and all this sort of thing, it just, it

has this mental burden that's sitting

there and in, and, you know, devalues your

life experience, which is not what Bitcoin

is about. So Guardblock was about trying

to solve this problem for ourselves, for

our business. And we've now, and we're

really happy with it and we're, we're

satisfied and we've like, okay, this has

reduced our mental burden tangibly for us

and our business. So how can we make this

available to other people, to Australians

and, and, and people overseas as well, uh,

to, to have the same benefits, to have

safety nets, to have reduced mental burden

for the Bitcoin custody. And so that's why

we built Guardblock and it's, uh, yeah,

we're really happy with the product where,

uh, and it's good to see the, you know,

people, people taking it on and, and, uh,

getting some value out of it. It's, it's

really good to see. And, uh, yeah, I mean,

I can, I can start to explain how it works

or go through any nuance or whatever you'd

like, whatever direction. Yeah. Let's

definitely talk about how it works, but I

do just want to add the whole mental

burden is such an important factor because

since the Coldcard hack, like I've always

had a low grade anxiety about my self

custody. Did I do a right? Did I miss a

step? And I always go back and check it

and make sure like I do a health check

every three months, um, on my self

custody, but it's still like my low level

anxiety is now medium level anxiety. So

it's just, it's, it's so important to, to,

yeah, think about how to reduce that

emotion around Bitcoin because one Bitcoin

is already volatile and there's some

emotion to carry there. And, you know, for

the first time in my life, when I got into

Bitcoin, I was like, finally felt

optimistic about my financial future. Like

I could just breathe out and not worry so

much that I'm like trying to outpace

inflation. Um, and you know, that, that's

Bitcoin, but the self custody side is, is

the part that just, yeah, still gives me a

lot of anxiety. So let's talk about the

solution. How does it work? Yeah. So it's

basically the way we describe it is we

call it collaborative security. So there

are plenty of products out there that are

collaborative custody products. And we

talked about custody earlier. We call

ourselves collaborative security because

we're not about taking custody of your

funds. We are, we are non-custodial in

that sense. And so it's an important

distinction to make, but ultimately what

you're getting with Guardblock is you

sign up for an account, you get your

account inside your account. You can then

create what we call vaults. Each vault is

itself a multi-signature Bitcoin wallet.

So you can create multiple wallets,

multiple vaults for different use cases.

So some people might keep it simple and

just have one, one personal vault for

their personal Bitcoin stack, but you can

create multiple vaults or multiple multi

-sign wallets for an SMSF account, a

business account, a family trust, maybe

one for each child, uh, whatever you want

to do. It's very flexible with exactly

what you want to do. But at its core,

you're creating a vault and each vault is

a two of two multi-sig wallet, but you are

removing the complexity of having to set

up your own multi-sig wallet yourself.

Because if a lot of people get this idea,

okay, I'm going to go straight for, for

multi-vendor multi-sig and I'm going to go

the whole hog. And then they realize that

it's, it's quite complicated. It's quite

tricky. There's room for mistakes. There's

lots of backups to manage all this sort of

thing. And while that is still maintained

as the gold standard self-sovereign

pathway, it's not the right fit for

everyone out there. Like there's

definitely hardcore Bitcoiners go for your

life, go and do your research and go and

set that up yourself. But if you're

someone who's doesn't have the time,

doesn't have the technical ability, then

you want to look for an option, which

still gives you the same security benefits

with a couple of trade-offs, which we can

go into as well. But you are getting those

security benefits without having to spend

10,000 hours researching and, and, and

then constantly having that mental burden

just to upkeep it and make sure it's up to

scratch. So when you set up your vault

with us, you just bring a single key and a

single device. So you've got your single

hardware wallet has to be a compatible

wallet, which we can get into again as

well a bit later. Uh, and you use that to

set up your Guardblock vault. You

register that with us. We give you what's

known as a vault descriptor. Uh, the

normal parlance is a wallet descriptor. So

every multi-sig wallet has a wallet

descriptor. It's basically a block of

text, block of code, which tells the

wallet what signatures are required to

move Bitcoin. And uniquely for us, uh, is

it includes the time lock information. So

we use time locks in order to maintain

the, uh, the functionality of the wallet

and the different recovery pathways that

we have available. And it's through those

time locks that we can say that it's a non

-custodial service because by default, any

keys that we have cannot move your funds.

So you still retain full sovereignty of

your funds. Only you can initiate and sign

transactions and, and, and actually move

Bitcoin on the platform. We can't do it,

uh, once you've set up a vault with us and

move some Bitcoin into that vault. Uh, but

there are some recovery cases where that

does change based on time locks. Uh, so we

can dig into that in a moment, but end of

the day, what you're getting when you set

up a Guardblock vault with us is you're

getting a multi-sig wallet, but you're

only having to bring a single key. You can

then use that single key to move funds

when you need to, but you get a lot more

security benefits versus just setting up a

wallet with a single key on your own

separately. And the main way we do that is

through spending controls and co-signing.

So when you initiate a transaction with

us, uh, with a Guardblock vault, uh, it

requires a co-signing key. So straight

away, you can see the security benefit

that you get across, uh, versus a regular

single-sig vault. If you have a, uh, if

you make a transaction, we need to co-sign

it for you. So what that means is if

someone somehow got access to your private

key, they found your device, they found

your pin, or they found your seed phrase

backup, and they were able to restore your

private key elsewhere. They still would

not be able to move your funds because

they would also need the Guardblock co

-signing key to co-sign a transaction and

send Bitcoin out onto the network. So they

would, so an attacker that did find all of

your information would still need to know

about Guardblock. They would need to know

your Guardblock login. They would need to

know your two-factor authentication so

they can get into your Guardblock login.

So it's a lot of extra hurdles for an

attacker to get over before they can touch

your funds. So straight away, you get that

really robust upgrade to your security

above a single-sig wallet. Yeah, that

makes sense. It kind of reminds me of the

days where, like, the banking industry had

to tighten up their security because,

like, family used to steal from each

other, like, steal money. And then now

they have to, like, put in all these,

like, extra questions to verify. But

anyway, let's actually talk about time

locks because that is a really cool

concept that's only available to Bitcoin,

as far as I know. Like, for the first time

in the entire history of humanity, we have

money that can be locked away into the

future and not even you can access it. So

let's talk about how those work. Time

locks are cool. So for a lot of people, it

might be a new term, a new concept. But it

has been in Bitcoin since about 2017,

really got a lot of usage 2019. It's

actually used to underpin the Lightning

Network as well with how channels are set

up. They use time lock protocol stuff to

operate that. So people are taking the

time lock concept and they're using it for

lots of really interesting things. And

with time locks, there's two kinds.

There's absolute time locks and there's

relative time locks. With hard block, we

use relative time locks. Absolute time

locks are interesting. So people are doing

some interesting things with them. A cool

example is people are thinking about

mining subsidies. And we're talking, you

know, hundreds of years in the future

where the mining subsidy might be quite

small. And so how do you incentivize

miners to keep mining Bitcoin and keep the

security out, keep the network going if

transaction fees don't pull their weight?

And so what people can do today is they

can actually set up these time locks to

have these like caches, these like

treasure troves in the Bitcoin network,

you know, 50 years into the future, 100

years into the future. And so when someone

mines that block in the future, they get

the Bitcoin that's locked up in that time

lock. And so it incentivizes miners to

keep mining. So there's some really

interesting concepts happening around time

locks. And we mentioned the lightning

network as well. But with Guardblocks, so

we use relative time locks. So relative

time locks let us do interesting things.

So when you register your multi-sig wallet

with us, your vault, we give you some time

locks which denote the recovery pathways

available to you at that time. Right. So

the first one is secured by a time lock

that is, I think it's 57,000 blocks into

the future. It's 57,000 and something,

which is basically 13 months. So time

locks are a way to quantify time denoted

by the Bitcoin blockchain into your

transactions, your smart contracts, if you

want to call them that, and your wallet

setups. So that first time lock that's 13

months into the future, when that time

lock expires, it changes the way the

wallet works. And specifically with a

guard lock vault for our most basic vault,

it's called a shield vault. You have this

first recovery time lock, which is

actually to protect you from us. And we

figured that that's really important is we

want people to maintain their sovereignty

no matter what happens to us. So if we got

hacked, we went out of business, we

disappeared, we all got hit by a bus,

government took us over and told us to

seize people's funds. That first time lock

protects you, protects the guard lock

users from anything happening to us.

Because what happens when that first time

lock expires, 13 months, it changes the

multi-sig setup to no longer require that

co-signing key that I mentioned before. So

under default operations, normal

operations, nothing's gone wrong with

anything. You can initiate your

transaction, sign it with your key, then

our co-signing service will co-sign that

transaction, Bitcoin moves on. But if we

disappeared and we could no longer co-sign

because we've been hacked, taken offline,

gone out of business, whatever's happened,

we can no longer co-sign. So suddenly

you're like, well, how do I move my

Bitcoin? It's now stuck because I can't

get a co-sign in. You wait for that first

time lock, then what it does is it changes

the multi-sig setup. It pulls out the

requirement for that co-signing. So

suddenly you can just take your single

key, your single device, and you can move

your funds without us. So again, hopefully

it never happens, but in the scenario

where something happens to us, your funds

are still recoverable. And we call that

the unilateral exit pathway or the self

-recovery pathway for a simpler term. But

it means that your funds are not locked

away. And then I'll go through one more

recovery pathway because I'm conscious of

time. Beyond that, we have another time

lock. This one activates at 62,000 blocks

15 months into the future. So after 15

months, it changes that multi-sig quorum

again, and it actually activates a third

key. And that third key is the Guardblock

recovery key. So by default, under normal

operation and under that first time lock

section of time, this recovery key can't

do anything. It just sits there. It's

dormant. And if that second time lock

expires 15 months into the future,

suddenly that recovery key does become

active. And so that's your safety net. So

if something happens to you, your key,

your backup, you lose everything, you have

a house fight, you have the worst case

scenario, your device breaks, and you lose

your backup. You know, we're talking worst

case crazy scenarios. You've got this

safety net. We simply just wait for that

time lock to expire 15 months. And then

you go through a recovery process with us.

We call it the Guardblock recovery. You

go through that process. We verify you. We

do a bunch of stuff. And then we are able

to move funds to a new location that you

specified. So we can move it on your

behalf. So that's the only time where we

technically have a level of custody over

your funds. But it's obviously very

strongly ring-fenced. And it's baked into

the wallet descriptor, into the multi-sig

wallet setup. And it's controlled by the

Bitcoin protocol itself, those time locks

and the Bitcoin blockchain itself. So you

know that it's not just based on a

promise. It's not based on our, you know,

individual code is literally there on the

Bitcoin network. It's baked into the

transaction. When you first move the

Bitcoin into the vault, it's there. So

that key by default can't do anything. But

if you lose everything, worst case

scenario, after a bit of time, it does

become active and you can then move funds.

And I'll just mention one last thing. With

the time locks, you can refresh them. So

obviously on normal operations, you don't

want those time locks to expire. You don't

want the co-signing to be ripped away

after 13 months. And you don't want the

Guardblock recovery key to become active

after 15 months if everything is normal.

If you've still got full access to your

devices and your backups and there's no

issues and we're still operating and we

haven't been subject to some sort of

takeover or government order or something

like that. So you simply do a refresh. So

it's kind of like a UTXO consolidation if

you've ever done one of those before. But

you're basically just doing a transaction

to yourself. So you have your Guardblock

vault. You have your Bitcoin sitting

there. Once a year, we typically say do

this every 12 months. You just do a

transaction to yourself. You're literally

just picking up the Bitcoin in your vault

and you're moving it to a new address in

the same vault. And that refreshes that

time lock for another 13 months.

And I can, as a customer, I can do this at any

point within the 13 months. Basically, I'm

just like kicking the can down the road.

Exactly. Yeah. So we would send you some

notifications saying, hey, it's time to do

your rollover. It's typically a once a

year thing. So we would say, you know,

it's part of your financial year audit

type stuff where you're doing your taxes.

That's where you'd log into Guardblock.

You check your balance. You check your

spending controls are set up the way you'd

like. And then you do your rollover. And

so you just do that transaction to

yourself. And that kicks the can down the

road for another 12 months. And so then,

you know, you can forget about it, get on

with your life and come back to it at, you

know, next year's tax time. But you can do

it sooner. So you could do it every six

months if you want. If you want to make

sure that you've got a really long runway

for completing your rollover, you can do

it whenever you'd like.

So it sounds to me that this product like still

requires you to have a high level of self

responsibility when it comes to your own

backup, because obviously, you know, there

are scenarios where you definitely want to

be able to have access to your Bitcoin if

something happens. Is that the right way

to put it? Like it doesn't like it kind of

it's it builds on top of your self custody

doesn't remove the necessity for you to

still have responsibility around your self

custody. Yeah. So you think of it like

you're augmenting your setup to add in a

safety net, but you're still having to

have your your basics covered. So it saves

you from having to go all out with

maintaining setting up and maintaining a

very robust multi-sig setup on your own.

So it saves you from that sort of mental

burden. But in terms of just maintaining

your single device, single backup, yes,

you still want to maintain that

specifically just for the scenario where

we disappear. So if we went out of

business, we got hacked, government

takeover, you know, something crazy

happens to us, which hopefully never

happens. But in that scenario, that's

where you still want to maintain your

basic level of I've still got my device

and I've still got my backup ready to go.

But you're not having to manage multiple

devices, multiple backups. And again, it's

just for that scenario where we

specifically disappear in and beyond that,

your basics are because we've added in

these safety nets, you can be I don't I

don't want to be giving bad advice because

I could say like, oh, you can actually be

quite a lot more reckless because you've

added in this safety net. You don't need

to be as precious with your device and as

precious with your backups as you

otherwise would be. That's not the

impression I want to give. Technically,

yes, you can be a bit more fast and loose

with things because an attacker, if they

did stumble across your device and your

pin code and your backup, they still can't

move your funds. So in that regard, you

can be a bit looser. You don't have to be

as precious with, you know, if you've got

a you don't have to make sure it's, you

know, kept in the most secure laser grid

possible setup if it's off site, because

if that Bitcoin is custody and guard

block, even if if an attacker found that

backup, they still would not be able to

move your funds. So you could be a bit

looser. So rather than put it in a in a

vault, in a bank safety deposit box and

under lock and key and all this sort of

thing, you can actually just go to your

still trusted friend or family member and

say, hey, can you please store this for me

and keep it safe? So that's your off site

backup sorted. But if they want to betray

you, if they decide to betray you, like

you said before, the banking system had

issues with family members stealing other

family members funds. If you just had a

single single device, single six setup

without Guardblock and you made your

backup and you gave it to a family member,

they could decide to betray you. They

could bust out that backup and they could

restore your private key and they could

move your funds because that's what it is.

It's a plain text backup. There's no extra

extra bells and whistles on there. They

don't need your device pin. They can just

go and set up a new wallet and plug in

your seed words and move funds. So in that

scenario where you don't have someone you

can trust, then you might need to go a bit

extra how to secure that backup. But if

those funds are held with Guardblock,

even if that family member tries to betray

you, they would still need access to your

Guardblock account, your Guardblock 2FA.

They'd need us to co-sign that

transaction. So it saves you from the

scenario where someone decides to betray

your trust by keeping a backup with them.

Yeah. So it's something in between, like

you don't have to go all the way down to

securing your backup or your key in a

laser activated Bitcoin vault facility,

but you also wouldn't put it on like your

fridge with a fridge magnet displayed for

anyone to see, right? Like, so yeah, I

guess there's a medium, but yeah. What are

the trade-offs of this product? So the

trade-offs are, the main one would be

privacy with us. So you are trusting us

with knowledge about your, so we need your

XPUB. So part of the vault setup process,

when you create that multi-sig wallet with

us, you are exporting your XPUB from your

device to Guardblock so that we can

create the wallet for you. Now, this is

different. This is not exporting your

private key. Your private key never leaves

your device. We never ask for your private

key. We'll never, we'll never ask for your

private key. We'll never ask for your

backups or seed words or anything like

that. And, you know, public service

announcement, no one should ever ask you

for your, for your private key or your

seed words or anything like that. If you

ever receive that from anyone, whether it

be Guardblock or your exchange or a

wallet manufacturer, that's a scammer. So

just a PSA, never, ever, ever share your

private key ever. Um, so yeah, but the

trade-off is privacy. So you're sharing

your XPUB with us, uh, and we are able to

see your transactions because we are co

-signing your transactions. So that

doesn't mean that, you know, we're logging

in and being like, Ooh, let's, let's see

what they've done today. Um, but we do

have the ability because we need to be

able to sign your transactions for the co

-signing, uh, we can see what transactions

you're doing. So it's a, it's a privacy

thing. Um, the other trade-off would be

in, in very extreme scenarios, um, where

what's an example here. Yeah. So in the,

in the scenario where you are relying on a

Guardblock recovery, so you've lost your

device, you've lost your backup, you've

lost everything. And you are relying on

that second time lock, the 15 month time

lock where the Guardblock recovery key

becomes active. In that scenario, you are

trusting us to do then do the right thing.

You are trusting us to not move your funds

immediately and be like, Ooh, they let

their, they let their time lock expire.

It's time to, it's time to swipe up their

Bitcoin. Uh, you are trusting us to be

like, okay, no, their time lock has

expired. We're going to keep attempting to

contact them, contact, contact, wait, or

wait for you to contact us, whatever the

scenario is and wait for your instructions

to then move the funds to a new location.

So there is that moment there. If that

second time lock expires, that we are

going to do what we say we will do, which

is help you restore access to your funds.

And that extends to, um, inheritance

protocols as well, because that's the most

likely scenario of why a second time lock

would expire is in an inheritance scenario

where you've passed away. So you were

unable to do your rollover transaction.

Um, you're trusting us to then basically

still do that recovery process I

mentioned, but for your executor and for

your heirs. So those are the two sort of

major trade-offs. Your privacy and then

the trust in us for that ultimate recovery

scenario, the disaster scenario, which

again, hopefully never happens, but that's

the safety net. And we're obviously highly

incentivized as a business to maintain

that. Like if we, the moment that we fail

in that, um, that obligation for a single

customer, our business is done. It's over.

So we're very highly incentivized to do

what we say we're going to do, be that

safety net and help you recover your funds

in that absolute worst case scenario.

Yeah. Well, let's talk a little bit about

the inheritance because I assume that a

lot of people who are parents would

actually find this kind of product very

appealing. Um, there's really not the

strongest solutions out there when it

comes to like, how do you plan inheritance

if you do have self custody? Like I have

some girlfriends, for example, that may be

single moms and they have young children,

you know, they absolutely believe in multi

-sig. They believe in single-sig with a

passphrase and doing it all yourself. But,

um, when it comes to like, you know, what

if I get hit by a bus tomorrow, how is my

10 year old son going to actually get

access to that Bitcoin? So how does the

inheritance piece work? Yeah. So before we

talk about card block, we'll talk about,

you know, the problem of inheritance with

Bitcoin in the first place. So you're

exactly right. You can, for most people,

they will be the Bitcoiner in the family.

They will be the one that has understood

Bitcoin and is deemed it worthy of, of

investing in and having some Bitcoin, uh,

for long-term value accumulation and that

generational wealth. You want to be able

to pass it on, um, and, and make sure that

your, your inheritors can enjoy, uh, that

Bitcoin in the future. And, but you're

then straight away, you're presented with

security issues because, and, and also

trust issues as well. Uh, because you are

having to, you've done all the work, you

understand how your device works, how your

setup works, you understand where your

backups are, what your pin codes are, but

your family doesn't. Uh, your heirs may

not. And so you're immediately presented

with a, with a conundrum. Um, what

information do I put to, so that my heirs

can work out how to get access to my

Bitcoin. If I disappear, if I get hit by a

bus, if I pass away, whatever happens. And

that obviously then creates its own

security holes, because if you do a nicely

documented step-by-step guide of here's

how to get my Bitcoin. If I die and you

print it out and you put it on a piece of

paper, well now that's another security

vulnerability. Because if an attacker

finds that, a thief finds that, or someone

you don't trust finds that, then they can

potentially take your funds, uh, and, and

your kids will be left with nothing. Your

heirs will be left with nothing. So again,

it's one of these things where there is

definitely a way to do it yourself, but it

does require time, effort, energy,

expertise, and a lot of research to make

sure that you are doing it safely and

correctly, and you're not opening up

security holes. So that's where there are

products like Guardblock that are sort of

coming online specifically to deal with

this problem. And so the way that we

tackle it is again, using those time

locks, but also using the basics of

customer support and advice and, and just

working with you and talking to you and

consulting with you and answering your

questions, whether it be yourself or your

heir or your inheritors or executor,

whoever that is, that's part of the

service as well. So with Guardblock, we

cover the technical side. We've already

covered that already with your, uh, your,

your spending pathways into recovery

pathways. Um, that covers the technical

side. So through that, your Bitcoin is not

lost in the, in the scenario where you

die, uh, and your, um, your heirs, your

executor has no idea about your Bitcoin

stuff. They, they, they just know they've

got Bitcoin, but they have no idea where

your devices are. They don't know what

your pin codes are. They don't know where

your backups are. They might have the

device, but just simply not know the pin.

And at that point they're stuffed. Um, if

they have the backup, um, then maybe, uh,

they, they would be fine, but then they

would still need to understand what to do

with the backup, how to use it safely. And

the worst case scenario is something that,

that, um, I think about quite a lot is how

many inheritance situations will there be

out there where an inherit, someone passes

away, they, they've got a bunch of

Bitcoin, their inheritors find their

backup, their seed backup. And they're

like, Oh, I know this can get Bitcoin. I

need to get access to this Bitcoin. And

then they contact some random person

online because they don't know what to do.

And they say, okay, help, help me out.

Here's the seed words. And then the

attacker goes, Oh, goody, goody, goody,

goody. Um, thank you for the, for the, for

the free Bitcoin. So that's why you need

to be very, you do need to leave very

clear instructions for your, for your

heirs on what to do and how to safely

restore that Bitcoin, get access to it.

And then further what to actually do with

it. How do they then custody it themselves

to make sure that it doesn't get lost or

lost in a hack or vulnerable to some cold

card exploits or whatever, or if they need

to sell it, how do they sell it safely? So

we cover all of that with Guardblock.

We've got the technical side covered, but

then the process is actually quite simple.

If you passed away, your executor, um,

gets something called probate. So probate,

it's a, it's a standard sort of process

when people pass away in Australia. Um,

they would come to us, so your executor

would come to us with probate. We would

ask for a death certificate. We would

verify the death certificate and we'd

verify the probate. We'd verify the

executor as well, obviously. Uh, once

we've done all of that, then we can move

to the next stage, which is, okay, the

funds are here. We can restore them. We

can help you do it. Um, what are we going

to do with these funds? And we actually

get on calls just like this, uh, or we can

meet them in person and actually hold

their hand and make sure they understand

what they're getting, how to store it

safely, how to sell it safely. If they do

need to liquidate some to pay for your

grandiose funeral or whatever it is, um,

we do all of that with them and we'll do

that with your executor and we'll do that

with your heirs as well. So that's all

part of the service. Um, yeah, so that's,

I mean, that's a sort of overview. We'll

speak briefly about wills as well, because

that's another very important part of this

that a lot of Bitcoiners have probably got

in the back of their minds somewhere, but

they're like, oh, I'm not, I'm not going

to die tomorrow. So I don't need to worry

about a will. It'll be fine. Um, you do

need to worry about a will, um, because

otherwise the state will get their grubby

hands up in your business and they will,

they will take, take, take. Like, so set

up your will and specifically set up your

will with respect to Bitcoin. So, but you

need to do this carefully because what a

lot of people don't understand is that

your will can become public information in

the result of your death. So you don't

want to be putting things like your seed

phrase, your location of devices, your pin

codes, anything like that in your will.

Absolutely not. Um, what lives alongside

your will is a letter of wishes. Now a

letter of wishes does not necessarily

become public information, but it still is

sensitive in that it might be viewed by

lawyers or judges or, or their clerks or

accountants or, or various other people

involved in your death. So again, you can

be a bit more detailed with, with what's

going on with respect to Bitcoin and other

things in your letter of wishes, but still

a little bit controlled. And so we help

you with this. We give you a bit of

coaching. We give you some, uh, some

documents to read through so that you can

establish these yourselves. But your

letter of wishes is basically what your

executor would come to us with and say,

okay, this is what the person who's passed

away wants to happen with my Bitcoin. And

it could be as simple as, uh, go and talk

to Guardblock and they will help you get

my Bitcoin back. It could be as simple as

that. Um, but it's ultimately up to you.

And if you've got a very complicated

setup, you want very intricate plans, then

you might want to go and get some extra

help. Talk to a, you know, a legal expert

that can help you in a state planner. Um,

that's probably very important. If you

have a significant amount of wealth and

you've got very intricate family and

inheritors involved in the process. But if

it's a lot more simple, then you can keep

it simple. Just do your own research with

that one. Uh, end of the day, they'll come

to us with the letter of wishes. We will

help them carry out that letter of wishes.

Yeah. Um, but going back to the hardware

wallets, what hardware devices are

compatible with guard blog at the moment?

So with our Guardblock multi-sig wallets,

we use a protocol. Well, it's a, it's a,

uh, script called Taproot multi-sig, uh,

sorry, Taproot mini script. Taproot mini

script is what we use to set up our, our

vaults. And Taproot mini script is a, it's

a scripting language, uh, that lets you do

a little bit more fancy things with, uh,

Bitcoin wallets versus just a standard,

standard sort of, uh, protocol wallet. And

so we are a little bit constrained with

the hardware wallets we support must

support Taproot mini script. And so we

hope to support every hardware wallet.

Like we, we generally want to support

every hardware wallet on our platform. Uh,

we are simply constrained by whether that

hardware wallet has enabled Taproot mini

script on their device. And so right now,

uh, I can actually do a bit of show and

tell. Um, I've, I've got my kit here with

all my different wallets for testing. So,

um, obviously we've got the, uh, you know,

the, the, the fan favorites, the cold

cards. So the Coldcard queue, Coldcard

Mark four and the Coldcard Mark five. Um,

they, they were very, they, they were

early with supporting Taproot mini script

and, you know, up until three months ago,

um, very good choice, very highly

recommended by, by staunch Bitcoiners. Um,

we no longer, we still support them, but

we don't, we don't recommend them. Um, if

you still got one kicking about, you can

still jump on and test with one. If you

want to try out the product, you can do

that absolutely free. Uh, and you can use

your Coldcard. So if sitting there

collecting dust, um, you can do that. You

can test out Guardblock and see how it

goes in a completely risk-free way. So

yeah, Coldcards, but we'll, uh, we'll

move on from them. Um, the other devices

are the, the BitBox. So I've got my, my

BitBox here, nice little, nice little

device here. Um, so the BitBox O2 and the

BitBox O2 Nova, uh, we support those

devices as well. Um, they're very good.

Um, they're, they're quite interesting in

the way they navigate. Like they don't

have any buttons. They've got a, they've

got a screen and then they've got these

like touch sensitive panels on the top. So

you sort of navigate by, by touching and

prodding like that. It takes a little bit

getting used to. I was, I was a bit like

caveman when I first, first used one of

these. I was like, Ooh, it took me a

while. Um, but you get familiar with it

and it's a very good device there. And

interestingly, I just saw they, they just

announced, um, lightning, uh, lightning

support using, using their, using the

BitBox as well. So you can easily move

Bitcoin from your standard on-chain, uh,

BitBox O2 wallet into a, a lightning

wallet, um, directly using the BitBox app,

which is, uh, that's a pretty cool

feature. Uh, so I'm keen to try that out

myself. Um, other than that, we support

the, uh, ledger devices. So currently we

support the, uh, uh, what are called the

classic ledger signers. So these like

little USB style ones, like this is the

ledger nano S plus. Um, and to be honest,

before I joined this project, I was like a

lot of hardcore Bitcoin is quite skeptical

about ledger because obviously they

support shit coins and they have had some

data breaches in the past. Um, mostly

because it will all entirely because of

their payment processor. It wasn't

actually because of the company

themselves. It was their payment processor

that had some data breaches, but that kind

of soured their reputation amongst, uh,

the hardcore Bitcoiners. So I'd avoided

them until I, um, joined this project, but

I've actually come around quite a bit.

Like actually since using the devices to

do all my testing and, and, uh, and stuff,

I actually really liked them. Uh, I've,

I've come, come right around to, to the

ledger devices. I think they're, I think

they're great. Um, they do have a good

track. The devices themselves have a very

good track record. They've been in market

for a long, long time. They've got a huge

team of photographers behind them. And as

a bonus in Australia, you can go to office

works and you can pay in cash to pick up a

ledger wallet directly from an office work

store in cash, which is great because then

you're not having to, when you buy a

device online, you're not having to give

up an address and putting your payment

information, all that sort of stuff. You

just go and pay cash. It's fantastic. So,

um, that's a really good benefit. Um, we

have just launched support for the legend

nano, which is like a, it's a, it's a

slightly bigger device. It's got this ink

screen on there. Touch, touch capable. Um,

this is really good because it makes it

really easy to view and verify things like

the vault descriptor. When you're setting

up your, your, uh, wallet with us, you can

look at the whole string of text all in

one place when you're verifying it. On the

screen. Uh, so that's super handy. So

that's a cool device as well. Um, in

theory, we can support all ledger devices

because all ledger devices are meet

taproot mini script compatible, but we

haven't completed full testing for every

single device yet. Cause they've got quite

a few on the market. So right now it's

just the classics. So the ledger nano S

plus and the ledger nano X and then the

ledger nano. So the bigger one, uh, and,

but at the end of the day, we want to

support more devices. We're hoping the

Trezor adds support soon. Um, I'm hoping

that the, these guys, um, you know, local

fan favorite in your area, the seed

signer. We're hoping they add, add a

taproot mini script soon. Um, because

yeah, we, we want to support all these

devices. Yeah. I have been told by seed

devices. Yeah. I have been told by seed

himself. He's like, watch this space. So I

was like, okay, I might just like every

few months, just prod him along and be

like, Hey, um, but I was going to ask you

with ledger, do you know if they've got

the capability for you to generate your

own seed and then put into the device or

is it just a device generating seed? Uh,

right now. So on, on the device, you can

only generate it with, uh, with their, um,

with their, uh, entropy. So you're not

able to add in dice rolls or anything like

that. Um, I, they haven't announced plans

to support it. So I think if you are going

with ledger, you are relying on their

native seed generation capabilities on the

device. Um, in theory, you can, um, if you

really wanted to, you could generate a

seed elsewhere, um, through dice rolls

with a different device, different setup,

and then you can import that seed, um,

using the seed phrase backup into a ledger

device and do it that way. Um, so that's

up to you, but obviously you need to be

very careful and do your, do your due

diligence, do your research to make sure

that if you are generating a key

elsewhere, you know, check that it is

compatible, check that you are generating

your entropy correctly. If you are doing

dice rolls or something like that, uh,

really make sure you are genuinely

creating enough entropy, um, on the

device, uh, sorry for that key before you

import it and before you use it with real

Bitcoin. Um, but that being said with,

with ledger and, and, you know, with on

seed on device seed generation, the, the

Coldcard incident was obviously an issue

with the, the onboard seed generation, uh,

for that device. We, we would hope that

every single other device manufacturer has

now done their due diligence and made sure

that there's no vulnerabilities in their

native seed generation properties. So

fingers crossed, we don't see another

incident like that happen ever. Um, and

again, one of the failings with Coldcard

was that they only had one or two people

ever looking at this sort of thing.

Whereas the benefit of ledger is they've

got a massive team of cryptographers that

are constantly pouring over their device

and their setup and this sort of thing. So

we're hoping that with more eyes means

less chances of an exploit, like what

happened to Coldcard slipping through the

cracks. Um, but the benefit, this is, this

is where it comes back to a benefit of

using Guardblock. So even if, so let's

take the Coldcard example specifically,

even if you're using a Coldcard mark

three and you generate a vulnerable seed

and someone could then recreate that seed

through the exploit, uh, remotely, if that

Bitcoin was held in a Guardblock vault,

they would still not have been able to

move your funds. Even if they recreated

your private key perfectly, if it was just

a single SIG set up, set up with a cold

card and the funds were just sitting

there, um, then yes, those funds were

vulnerable. And that's how most people

lost their funds in that, in that attack.

But if the funds were held in a guard

block vault using the same key, same

private key, same setup, same device, the

attacker would not have been able to move

your funds because they would have need

that co-signing key from us in order to

actually move funds. So that's still the

case with any of these other devices. If

you get just a Ledger Nano S plus costs 80

bucks at, at Officeworks pay cash, fully

anonymous. You take it home, you use the

onboard, um, app, you know, use the app

and the device to update the firmware and

then generate your own seed. Even if 10

years down the track, it turns out, oh,

suddenly we can reverse engineer and, and,

and pull out your, your private key. In

that scenario, if the funds were held in a

Guardblock vault, those funds are safe.

They would not be able to move funds

without the co-signing.

With your early

customers that you have acquired, what's

been some of the feedback that's come

through from them? So there's been a lot

of relief, I guess, uh, because there's,

well, yeah, there has been a lot of relief

because particularly because of in light

of the Coldcard incident, which we've

touched on a few times, there's been a lot

of people that are thinking, well, what

can I do? Nothing safe. I'm, I'm, I'm

scared. I'm concerned for my Bitcoin. I

don't know what to do. Maybe they've just

dumped it on an exchange and a custodian,

which is, you know, not the best idea

because you're opening yourself up to

massive counterparty risk. And so they

come to us and they say, what should we

do? What should we do? And so we straight

away be like, yeah, perfect use case

because you're, you know, these are

typically people that are not, um,

technically capable enough to sit down and

get three devices or four devices and set

up that multi-vendor multi-sig that is

considered the gold standard now for self

-custody. Um, the reality is there's just

a group of people. There's a huge number

of people out there that are just not

technically capable. And frankly, and I

know this is going to annoy some hardcore

Bitcoiners out there. Everyday, everyday

people shouldn't have to, you know,

understand all this incredibly intricate

stuff just to secure their Bitcoin. It

just shouldn't be that way. And so that's

where collaborative security models like

ours are coming in to fill that gap for

the people who just don't want to, or

can't, or don't have time to go the whole

hog and do their own, their own stuff to

the level that's now required. We're

coming in and filling that void and we're

providing a solution where people can go,

okay, I don't have to go out and get 10

devices and do all this crazy stuff. I can

just sign up for an account like I do

with, with other, um, services that I

might use and I just have to manage my, my

basic stuff, but I've got my safety net

ready to go. And it's all there. It's all

straightforward. And we're also tying up

the, the, uh, inheritance pieces and all

that sort of thing as well. So it's a lot

of relief, a lot of relief that, that is

coming to people that are, that are coming

to us and jumping in. Yeah, I bet, I bet

it is. Um, but what use cases are you

seeing come through? Like what are the

types of customers that are taking this

product up? Is it mostly like women, men,

parents? It's, it's a, it's a mix. Um,

there's, there's a big mix of people. A

lot of people are, you know, quite a few,

uh, older, older people, older Australians

who are thinking specifically about

inheritance, uh, are coming to us. Um, a

lot of people that are having like young

families, like they just had their kids

and, you know, they might be very

competent Bitcoiners, but they're still

thinking, you know, you know, hopefully

I'm going to live for another 50 years,

but what happens if I get hit by that bus

tomorrow? Um, is my, is my child going to

get access to my Bitcoin while they can't

even speak? And so it's people going

through those life changes, uh, are

suddenly thinking, oh, I need to make sure

I gotta, I gotta cover all this stuff now.

It's not just me on my own anymore. Um,

I've got, I've got other people to take

care of. And so, uh, they come to us to,

to explore solutions around that. And

obviously we do have a solution for your

Bitcoin to make sure it does safely get

into their hands as well. So people going

through life, life changes, life

milestones, people that are a bit older.

Um, but beyond that, it's, it's everyone.

It's, it's, it's, uh, both guys and girls.

Uh, and, uh, and it's people, you know,

that we did get quite a few people that

were specifically triggered by the cold

card incident, uh, rightly so. Um, so a

lot of people that were triggered by that

one. Um, and that's kind of it. It's, it's

really, it really comes down to, yeah.

Yeah. Inheritance is the big one. Uh, and

then, and then, yeah. Triggered by

security scares and stuff, which are only

going to get worse, frankly, as, as AI

models keep, keep going. So, you know, you

do need to take steps, whether it be, and

there's, and this is kind of everything

like another PSA in general is, you know,

maybe it is time to do a bit of an audit

of your cybersecurity in general. Uh,

whether it be the services you use, um,

how your data is held, how your Bitcoin is

held, like it is time to do a bit of an

audit of all of that stuff and reach out

to your, your friends and family as well.

And be like, Hey, how's it, how's your

cybersecurity? How's your scam awareness?

You know, scams are becoming phenomenally

sophisticated now supported by these AI

tools. And so, yeah, you need to, you need

to make sure that yourself and your heirs

and your family are all covered. Yeah,

that's really, really good advice. And I

appreciate you sharing that. Um, but let's

talk about pricing. So what is the current

pricing structure? What are some of the

things that people need to know before

they potentially look at signing up? Yeah,

so we, we've tried a very simple approach

to pricing and, and we, we come up a lot

cheaper than, than a lot of the

competitors out there. Um, you know, a lot

of these collaborative custody ones, which

have a lot of extra touch points and a lot

of extra, um, friction to get them going.

Uh, they do charge quite a bit of a

premium. So we've tried to, to find a

happy median there. So right now the price

is 0.2% of the Bitcoin held in garblock

faults, um, per year. So, uh, that's our

normal pricing. And, you know, we are

still fairly new in the market. We are

still taking customer feedback and making

tweaks and stuff. And we'll be announcing

some, some changes and some, uh, some

different levels, um, in the future as we

sort of refine our approach and talk to

more customers. Um, but yeah, 0.2% of

Bitcoin held across all vaults, um, per

annum. And right now we do have a promo

running. So if you sign up and fund a

vault before the end of the year, so

December 31st, 2026, uh, you get 50% off

those fees for your first two years. I

want to say two years. Uh, so you're

basically paying 0.1%, uh, of Bitcoin held

for those first two years. Um, sorry, per

year for the first two years. Uh, and then

after that, it'll, it'll go up to the

standard pricing. Uh, but that's it. We,

we, we wanted to keep things really simple

and straightforward. Like we, we're, we're

exploring like tiers and all this other,

other sort of stuff. Uh, but again, part

of our general philosophy for both hard

block, the exchange and Guardblock, this,

uh, collaborative security product is we

just want to keep things really simple and

straightforward in all regards, whether it

be using the product, how to set up the

product, uh, and how to, how to price the

product, how to pay for the product. We

want it to be really simple and

straightforward. So, uh, that's the

approach we're taking. Yeah. And are there

any setup costs or any other like contract

terms that users need to be aware of? No.

So it's completely free. Um, so you can

jump on and create an account for free.

You can do an intro call with us, uh,

completely free. That's just a, like a 30

minute chat where we can demo the platform

and go through your specific scenario and

give you some tips and advice about self

-custody in general and securing your

backups and all that sort of stuff. Um, if

you actually jump onto the platform, then

we, uh, we, we currently offering a free

consultation. So you get a one hour

consultation where we actually jump on

with a video call and we actually help you

set up your device. So you'll have your

device on your end. We'll grab the same

device on our end. So if you've got a

ledger, ledger nano, then we will have,

we'll sit here with our own ledger nano.

You'll be setting it up on your end. We'll

be clicking through with a, with a vault

on our end so that if you get stuck, have

any questions, something, something

doesn't seem quite right. We're at the

exact same step as you. We can, we can

talk you through that. So that's all free

as well. So yeah, there's, there's

absolutely no cost to get started. It's

just once you've actually got some Bitcoin

in the vault, uh, eventually we'll send

you out a monthly bill based on the, uh,

the Bitcoin held in the vault. Yeah. And

the two year discount that you guys have

running until the end of the year, is that

a lock-in contract? Nope. So there's no

lock-ins. Uh, we, we have absolutely no

lock-ins, no minimum periods, no maximum

periods, no nothing. So again, back to

that simplicity angle, you can pull your

funds out anytime. So if you jump in, you

deposit some Bitcoin and you decide a day

later that, sorry, no, I'm not into this.

I want to do something else. You can just

sign another Bitcoin transaction and move

your funds. We, we won't hold your funds

into, in captivity. We have no lock-ins.

We have no exit fees or anything like

that. It's literally just the Bitcoin

network fee. If you move Bitcoin in and if

you move Bitcoin out, just the network

fee, that's it. We'll only ever charge you

if you complete a month, uh, and you've

stored Bitcoin over that month, we'll send

you a bill for 0.2% of the Bitcoin held

divided by 12. Uh, you know, there's, I

mean, it's a bit, bit more complicated

than that, but that's effectively what it

is. And, uh, but yeah, you can move your

funds at any time. There's no lock-ins and

we physically can't lock you in. So if we

wanted to, um, lock you in, we physically

can't because you, again, back to the time

lock conversation, you can simply, uh,

wait for that time lock to expire and pull

your funds out. So even if we turned evil

and, you know, changed our pricing to be

10, $10 billion per day or something, or

the government mandated us to hold

people's funds or, you know, something

crazy happened. You can sit there pretty

because you just wait for that first time

lock to expire and you move your funds

without us anyway. So we physically can't

lock you in. Yeah. Well, I appreciate

So, thanks very much for coming on Mike and

discussing the GuardBlock product with the

audience today. Is there any final, um,

words that you want to share with the

audience? Um, yeah, I mean, maybe just a

couple of things. It's just, um, yeah, if

you're, if you're curious about the

product, just send us an email. Uh, our

email is, uh, help at GuardBlock.com. Uh,

so email us there anytime. If you have any

questions, check out the website,

GuardBlock.com. Uh, have a look around,

let us know if you have any questions. We

want your feedback. Um, we're, we're,

we're still in this sort of like building

phase. We've got the basics down, but we

want people to tell us what they want to

see, what features they want to have. So

let us know, you know, maybe you're 90% of

the way there, but you would, you need

something else to, to get you over that

line. Let us know because we're still

like, we're hungry for people to tell us

exactly what they want. Um, but end of the

day, we're just here to make sure that,

uh, people have a, a, a really good robust

security setup for their Bitcoin. And, uh,

and the other thing I would just say is

back to that general PSA of, you know,

we're in this phase now of these cyber

attacks and exploits and, and scans and

stuff. They're, they're really ramping up

with these AI tools. So you need to take

the time to upgrade your setup, uh, and

not just in regards to Bitcoin, your

cybersecurity in general, what services

you're using, what devices you're using,

real basic stuff, um, for yourself and

your friends and your family as well.

Great. Thank you so much. Thanks again.

That's all right.
