Check a Base USDC tx before paying for the clean receipt.
Paste a Base transaction hash. Devryno will only confirm whether matching USDC transfer logs exist and show a small preview. Pay 0.10 USDC only if you want the full machine-readable receipt JSON.
Free preview does not create a full receipt. It is a quick eligibility check for clients, DAO ops, bounty admins, micro-sellers, and agents.
