ERC-8126: AI Agent Verification
Ethereum standard for verifying ERC-8004 agents across five categories with a unified 0-100 risk score.
Overview
ERC-8126 ('AI Agent Verification') is a Standards-Track ERC (status Final), authored by Leigh Cronian and Chris Johnson and created January 2026, defining a framework for verifying autonomous agents registered through ERC-8004. It specifies five verification categories — Ethereum token, media content, Solidity code, web application, and wallet verification — feeding a unified 0-100 risk score across five tiers (Low to Critical). Verification runs off-chain (no gas) and supports zero-knowledge Private Data Verification for privacy-preserving checks, building on ERC-8004's ERC-721 identities and pluggable validation registries. It is a methodology for assessing agent trustworthiness, not a guarantee of safety, and a companion to ERC-8004 and ERC-8183.
