Crypto implications

ERC-8004 identity registries make agents composable with NFT marketplaces and reputation systems agents become tradeable assets with verifiable track records.
ERC-8183 job escrow with evaluator-only completion enables trustless agent hiring without intermediaries DeFi protocols can outsource computation or data labeling to agents with on-chain settlement.
TEE-based attested inference provides low-latency verifiable compute for latency-sensitive DeFi operations oracles and MEV bots can prove correct execution without revealing inputs.
zkML enables private inference with on-chain verification privacy-preserving credit scoring or KYC for DeFi lending.
Agentic Wallets give agents autonomous spending authority under policy limits automated treasury management or yield farming strategies can execute without human intervention.
Composability between ERC-8004, ERC-8183, and verification layers fully on-chain agent marketplaces with reputation, escrow, and dispute resolution.

The infrastructure for autonomous agent economies is snapping into place. Two Ethereum Improvement Proposals — ERC-8004 and ERC-8183 — define the discovery and settlement layers, while TEEs and zkML provide the verification backbone. Together, they enable a trust-minimized loop: identify an agent, hire it, pay it, and audit its work without a centralized platform.

ERC-8004 standardizes agent identity through three on-chain registries: an ERC-721 identity registry, a reputation registry with signed feedback, and a validation registry for independent checks like zkML verifiers or TEE oracles [^claim_1484]. The identity registry makes agents browsable and transferable as NFTs, with metadata that includes agent wallets, ENS, DID, MCP, and A2A endpoints [^claim_1485]. That turns agents into first-class on-chain assets — discoverable, portable, and composable with existing NFT infrastructure.

ERC-8183 complements discovery with settlement. It defines a Job primitive with escrowed budget and a four-state lifecycle: Open, Funded, Submitted, and Terminal. Only the evaluator may mark a submitted job completed or rejected [^claim_1486]. The spec supports composability with ERC-8004 by allowing optional attestation reasons on complete/reject events and recommending outcome-based trust signals and reputation interop [^claim_1487]. Hooks can wrap core actions (setProvider, fund, submit, complete, reject), but refund-by-expiry is intentionally not hookable — a design choice that prevents griefing [^claim_1488].

On the verification side, TEE-based verifiable compute runs inference inside an enclave, signs the output with a key bound to the loaded code measurement, and lets a verifier check the attestation chain rooted in the chip vendor PKI [^claim_1489]. Several production systems already ship attested AI inference using TEEs, including Marlin Oyster, Phala Network, Atoma Network, Automata, and Tinfoil [^claim_1490]. Chainlink’s verifiable AI stack says AI outputs can be mathematically verified onchain before state changes, using either zkML or TEEs to prove correct execution [^claim_1491]. Mina’s zkML library lets developers generate zero-knowledge proofs from AI inference jobs with private inputs and submit those proofs to Mina for trustless verification [^claim_1492].

Finally, Coinbase launched Agentic Wallets as wallet infrastructure built specifically for AI agents so they can spend, earn, and trade autonomously [^claim_1493]. This closes the loop: an agent identified via ERC-8004 can be hired via ERC-8183, execute work verified by TEE or zkML, and transact autonomously via Agentic Wallets.

The design choice for crypto-native builders is no longer whether to use AI with blockchain, but which trust primitive to pair with the workflow: reputation, TEE attestation, zk proof, or on-chain dispute resolution. The primitives are here. The market is wiring them together.
