The Ethereum community has proposed a new standard, ERC-8126, designed to establish a verifiable trust layer for on-chain AI agents. The standard standardizes five major categories of risk verification—including smart contracts, media content, Solidity code, websites, and wallet addresses—and outputs a unified risk score along with verifiable proofs. This enables wallets, marketplaces, and decentralized applications to make risk control decisions based on objective signals. ERC-8126 fills the critical gap between AI agent identity registration (ERC-8004) and trusted interaction, effectively creating a "credit scoring" system for on-chain AI agents.
Currently, on-chain AI agents lack a unified trust evaluation mechanism, making it difficult for users to assess their reliability. The introduction of ERC-8126 is expected to provide standardized trust credentials for AI agents, reducing interaction risks and promoting the healthy development of the AI agent ecosystem.
