Problem Statement

AI agents do work but leave no verifiable trail. When an agent completes a task — code review, data analysis, contract deployment — there is no standardized proof that the work happened, who did it, or whether the output was accepted. This makes it impossible to build agent reputation, compare agent quality, or verify claims of past work. ERC-8004 gives agents identity; this project gives them receipts — on-chain proof of completed work that other agents, platforms, and humans can independently verify.

On-chain proof-of-work receipts for AI agents, linked to verifiable ERC-8004 identities on Base. Agents mint WorkReceipt NFTs that record what work was done, when, by whom (ERC-8004 agent ID), and the result — creating an immutable, publicly auditable trail of agent contributions. Each receipt includes structured metadata: task description, deliverable hash, quality score, and client attestation. The WorkReceipt contract is DevSpot-compatible for discovery by other agents and platforms. Features include batch receipt minting, receipt querying by agent or client, and integration tests against the deployed contract. 41 tests. Deployed on Status Network Sepolia.
