When the x402 facilitator times out, stablecoins can move on-chain while the client receives an error and has no way to know whether the payment is confirmed, reverted, or stalled. In low-connectivity environments like Nairobi or Lagos, this is not an edge case. The fix is an ephemeral in-memory settlement state machine that polls the chain after a timeout, preserving stateless architecture while closing the confirmation gap. A bridge-level idempotency key extends the same pattern to M-Pesa-to-x402 flows, where M-Pesa considers a payment complete but x402 never delivers the resource.\n \n ","thumbnail_url":"https://img.transistorcdn.com/5jsccNzA2VS5A8o7Wh6TZK9cMfKFlwKAT0xOsKBE5w4/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzQxMjY5LzE2ODM1/ODI1NDAtYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
