Sovereign identity Interoperable formats

Smart Contract Standard Atributos

Permissions Permissionless agent registration; tiered trust model where validation level scales with value at risk
Development Tools Ethereum development tooling (Hardhat, Foundry); no dedicated SDK yet as of draft status
Protocol Maturity / Standardization Draft EIP; under community review; mainnet deployment of registry contracts anticipated but not confirmed as of early 2026
Trust Framework Three-layer trust: Identity registry (ERC-721 NFT-based); Reputation registry (score accumulation from task feedback); Validation registry (multi-stage verification scaling with stake)
Target Application Domain AI agent infrastructure, autonomous agent coordination, multi-agent systems, agentic DeFi, AI-powered DAO tooling
Deployment Model Three singleton registry contracts on Ethereum mainnet; agents instantiate identity tokens from the Identity registry
Standard Type Agent / Coordination Standard
