On-chain delivery receipts for x402 transactions on Solana. Hash-locked, escrow-grade, independently verifiable. Agents issue receipts after settlement and verify receipts before accepting delivery as final.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"receiptrail-receiptrail-x402-delivery-receipts","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.
