Did that Ink USDC transfer really land?

Inspect a real Circle-native Ink USDC receipt, match the recipient, amount and unique Transfer log, then check the block against Ink's RPC-reported finalized head. No wallet login or signing.

Evidence limits. A token Transfer on Ink is not the same as a paid invoice, legitimate work order, independent buyer, or recognized profit. This tool trusts Ink's public RPC and its finalized tag; it does not independently prove Ethereum L1 withdrawal finality or protect you against dishonest RPC servers. Always reconcile exact txHash + logIndex in your own ledger.

Verify an incoming on-chain transfer

No upload or account. This page sends only a public transaction hash to Ink's official public JSON-RPC. Addresses and transfer events are public onchain. It does not request your seed or wallet permissions.

Official Ink chain ID 57073. Native Circle USDC ERC-20 0x2D270e6886d130D724215A266106e6832161EAEd. Neither a bridged lookalike nor Base USDC qualifies here.

What can this prove?

Confirmed by the checker

Correct Ink mainnet chain, canonical Circle token, successful transaction, correct recipient, one unambiguous external Transfer event above your minimum, canonical receipt block hash, and finalization head at or after that block.

What still needs human review

Commercial buyer identity, signed scope of work, final payment terms, whether this tx was a gift or self-funded wash payment, independent RPC trust, tax accounting, duplicate settlement and any L1 withdrawal dispute period.

Original developer proof

Implemented as a lightweight static JavaScript module with no new packages. Unit tests inject synthetic bad receipt shapes; the real example fetches a separate third-party Ink transfer from the official RPC to demonstrate live operation. It never transacts.
