Ethereum ERC-8126: AI Agent Risk Score 0-100 with ZK Proofs

Ethereum has finalized a new standard, ERC-8126, to verify AI agents with a risk score from 0 to 100. This standard uses zero-knowledge proofs to help determine if an AI agent is trustworthy without revealing all its information. The standard was proposed in January 2026 and finalized in June 2026, a quick timeline suggesting broad agreement among developers. It addresses the challenge of knowing if an AI agent on-chain is safe to interact with. ERC-8126 creates a multi-layer verification framework. It includes five checks: Ethereum Token Verification, Media Content Verification, Solidity Code Verification, Web Application Verification, and Wallet Verification. Each check contributes to a unified risk score, where a low score means a trustworthy agent. This structural upgrade helps assess and trust AI agents at the infrastructure level. It matters because it provides a standardized way to ensure the safety and reliability of AI agents operating within the Ethereum ecosystem.
