Build with ERC-8004 Trustless Agents - on-chain agent identity, reputation, validation, and discovery on EVM chains. Use when registering agents on-chain, building agent reputation, or using the Agent0 SDK. Triggers on ERC-8004 and Agent0.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# ERC-8004: Trustless Agents ERC-8004 is a Draft EIP for discovering, choosing, and interacting with AI agents across organizational boundaries without pre-existing trust. It defines three on-chain registries deployed as per-chain singletons on any EVM chain. **Authors:** Marco De Rossi (MetaMask), Davide Crapis (EF), Jordan Ellis (Google), Erik Reppel (Coinbase) **Full spec:** [references/spec.md](references/spec.md) ## When to Use This Skill - Registering AI agents on-chain (ERC-721 identity) - Building or querying agent reputation/feedback systems - Searching and discovering agents by capabilities, trust models, or endpoints - Working with the Agent0 TypeScript SDK (`agent0-sdk`) - Implementing ERC-8004 smart contract integrations - Setting up agent wallets, MCP/A2A endpoints, or OASF taxonomies ## Core Architecture Three lightweight registries, each deployed as a UUPS-upgradeable singleton: | Registry | Purpose | Contract | |----------|---------|----------| | **Identity** | ERC-721 NFTs for agent identities + registration files | `IdentityRegistryUpgradeable` | …

How to install
mdr add tenequm/skills/erc-8004@sha256:68c7e49777272127The line at the top of this page pins the label v0.2.4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
