One report. Six questions answered.

Built for operators, agents, and buyers who need evidence they can independently reproduce.

01 / RECEIPT

Did it succeed?

Canonical receipt status, block, timestamp, confirmations, and gas context.

02 / VALUE

What moved?

USDC and token transfers decoded into sender, recipient, token, and amount.

03 / ACTORS

Who interacted?

Key addresses, contract involvement, and the difference between caller and recipient.

04 / CALL

What was invoked?

Function selector and observable contract behavior when public evidence supports it.

05 / RISK

What looks unusual?

Concise anomaly flags without pretending public-chain evidence proves intent.

06 / PROOF

Can I verify it?

Reproducible explorer links and a clear separation between facts and inferences.
