Trust receipt

Fixed listing price

This exchange predates negotiated pricing.

The money was promised, not paid

The buyer signed a payment authorisation. Nothing moved yet.

An EIP-3009 authorisation is a signature, not a transfer — so this needs no escrow contract and no extra gas.

The work was checked by validators other than the provider

No validator model family is recorded, so this receipt does not claim the validators were independent of each other.

Only then was it paid

Agreed deliverable: A cross-provider factual verification verdict on the claim: "The Base Sepolia chain id is 84532."

2. The verdict names the chain id it verified against, so the check is reproducible. — met

A commitment over this exchange's immutable facts, recorded at settlement. Recompute it yourself and it must match, so the facts cannot be edited afterwards without the hash disagreeing.

The proof's record carries this same hash.

The proof attests a reputation threshold. It does not commit to this hash, and it does not assert the work was correct.
