Payments & Remittance

About the project

USDC holdback for x402 agent payments on Solana. Agents pay tools per call over HTTP 402, and whoever routed the agent there should get a cut, but only once the call can't be refunded. Commish holds that cut in its own on-chain account for the refund window; then anyone can release it, and it can only go to the router. Live on mainnet: a router's cut was held 10 minutes, then released (6 Oct); a refunded call's cut was cancelled and the router got nothing (9 Oct).

Week 1 on Commish: the program went from 25,664 bytes to 9,296, so it deploys to mainnet for under 0.05 SOL. Rust core rebuilt with panics stripped, accounts read in place, and the client passes the address, bumps and rent. Code is open: https://github.com/bryankwandou/commi…

Commish is live on Solana mainnet (program CmSHpw9QTwvRSNCCBrQz275ESTCw8D79Z8jjhWmPJfFB). This week: rewrote the program in Pinocchio to fit a 0.05 SOL deploy, ran every instruction and attack on a live validator (41/41 checks), and shipped the app in four languages at getcomm…
