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.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 49 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.
Last 30 days — to 2026-09-10, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
