been thinking and experimenting with x402/MPP and the more i look at it the more the payments part feels like the easy bit
the hard bit is my agent has zero reason to trust the thing it's paying. it sends money, gets back some bytes, and only finds out later the data was stale or made up. can't preview, can't charge back, seller wallet is free to recreate so blacklists mean nothing
who is building the trust layer of agentic payments?
