Autonomous AI systems operating in crypto and Web3 ecosystems.
Start hereThey run an observe-decide-execute loop and can settle actions on-chain under explicit limits, permissions, and goals.

An agent turns a trade decision into signed requests that bundlers, EntryPoint, and allowance systems can settle as onchain state changes.

Intent-based execution turns a signed outcome request into an auction where solvers pay gas, route the trade, and settle only if constraints are met.

DeFAI agents usually think offchain, then use oracles and constrained wallet permissions to settle DeFi actions onchain with irreversible finality.

ERC-8004 standardizes an on-chain lookup layer for AI agents using an ERC-721 AgentID plus two 0–100 signal registries with off-chain evidence links.

ERC-8004 uses an ERC-721 identity token plus shared registries for reputation and validation so wallets and counterparties can apply consistent policy.

Agent reliability decays across tool calls and handoffs, so production safety comes from limits, verification, and observability, not better prompts.
