Verify independently (no byhuman.ink required)

Anyone holding the receipt JSON can confirm this digest is on chain without trusting byhuman.ink.

Compute the digest from the receipt: keccak256(canonicalize(receipt)). It should match the digest shown above.

Read the on-chain timestamp from the contract:

cast call 0xaaef72f5e32a238a2c91d04ab72bb7f1a2c22cd6 \
  "anchoredAt(bytes32)(uint256)" 0x54d67557bc54fe984d66f44f703a9589849ebdbebc71c6929aff8fbc198c8f9d \

A non-zero unix timestamp proves the receipt existed on Arbitrum Sepolia by that block.

canonicalize uses RFC 8785 JSON canonicalization. The contract address and network details above are the inputs needed for the independent on-chain check.
