Contracts & addresses

Everything onchain, by address

Current NOMEN deployment · Sepolia

Deployed September 11, 2026 under nomen-demo.eth, with a new operator wallet. The deployed registrar and resolver bytecode match the local build. Registry permissions, current ownership, Merkle eligibility, a real claim, non-transferability and ENS text records were checked against Sepolia. This is testnet deployment verification, not an independent security audit.

reader.nomen-demo.eth identifies NOMEN-owned test agent #10226. View the claim transaction. The older registrar at 0x0ae4…8686 and the old nomen.eth test namespace are no longer used by this app.

Historical trial receipts

These deployed contracts remain readable and historical evidence can still be verified. The current workbench no longer publishes trial receipts. New public feedback uses Orders: a 5 test USDC payment on the agent’s network commits the initial complaint draft; signed statements and subsequent updates are stored in Neon. The payment is not a verified purchase from an agent.

NomenEvaluationRegistry is an append-only receipt contract pinned to the ERC-8004 Identity Registry on each chain. It rejects unknown agent ids and stores only hashes, the wallet that submitted the review, the outcome and observation block. It has no owner, fees or upgrade authority. A receipt proves what that wallet recorded; it does not turn a user review into a NOMEN certification.

ERC-8004 registries

Sepolia, Arbitrum Sepolia and Arc share addresses because the testnet registries were deployed deterministically.

Tests

Thirty local Foundry tests (using registry mocks, not a live-network certification): ownership, merkle eligibility, double claims, non-transferability, revocation and re-claim, expiry, admin gating, deterministic scan proofs and append-only evaluation receipts. A separate test reproduces ENSIP-25’s ERC-7930 example byte for byte and checks the Sepolia and Arc chain references.
