# Send ERC-8004 Trustless Agents to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "erc-8004", "name": "ERC-8004 Trustless Agents", "source": "tencent", "type": "skill", "category": "AI 智能", "sourceUrl": "https://clawhub.ai/sp0oby/erc-8004", "canonicalUrl": "https://clawhub.ai/sp0oby/erc-8004", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/erc-8004", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=erc-8004", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "README.md", "SKILL.md", "lib/contracts.json", "scripts/common.sh", "scripts/feedback.sh", "scripts/query.sh" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-04-30T16:55:25.780Z", "expiresAt": "2026-05-07T16:55:25.780Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=network", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=network", "contentDisposition": "attachment; filename=\"network-1.0.0.zip\"", "redirectLocation": null, "bodySnippet": null }, "scope": "source", "summary": "Source download looks usable.", "detail": "Yavira can redirect you to the upstream package for this source.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/erc-8004" }, "validation": { "installChecklist": [ "Use the Yavira download entry.", "Review SKILL.md after the package is downloaded.", "Confirm the extracted package contains the expected setup assets." ], "postInstallChecks": [ "Confirm the extracted package includes the expected docs or setup files.", "Validate the skill or prompts are available in your target agent workspace.", "Capture any manual follow-up steps the agent could not complete." ] } }, "links": { "detailUrl": "https://openagent3.xyz/skills/erc-8004", "downloadUrl": "https://openagent3.xyz/downloads/erc-8004", "agentUrl": "https://openagent3.xyz/skills/erc-8004/agent", "manifestUrl": "https://openagent3.xyz/skills/erc-8004/agent.json", "briefUrl": "https://openagent3.xyz/skills/erc-8004/agent.md" } } ``` ## Documentation ### ERC-8004: Trustless Agents On-chain identity, reputation, and validation for autonomous agents. Now live on Ethereum Mainnet! ### Overview ERC-8004 provides three registries: Identity Registry - ERC-721 agent identities with registration metadata Reputation Registry - Signed feedback scores between agents/clients Validation Registry - Independent verification (zkML, TEE, stakers) ### Register Agent ./scripts/register.sh --uri "ipfs://..." --network mainnet ./scripts/register.sh --network sepolia # Testnet (no URI, set later) ### Query Agents ./scripts/query.sh total --network mainnet # Total registered ./scripts/query.sh agent 1 --network mainnet # Agent details ./scripts/query.sh reputation 1 # Reputation summary ### Update Agent ./scripts/set-uri.sh --agent-id 1 --uri "ipfs://newHash" --network mainnet ### Give Feedback ./scripts/feedback.sh --agent-id 1 --score 85 --tag1 "quality" ./scripts/feedback.sh --agent-id 1 --score 9977 --decimals 2 --tag1 "uptime" ### Networks NetworkStatusIdentity RegistryReputation RegistryMainnetLive0x8004A169FB4a3325136EB29fA0ceB6D2e539a4320x8004BAa17C55a88189AE136b182e5fdA19dE9b63SepoliaLive0x8004A818BFB912233c491871b3d84c89A494BD9e0x8004B663056A597Dffe9eCcC1965A193B7388713BaseComingTBDTBDArbitrumComingTBDTBDOptimismComingTBDTBD Contract addresses in lib/contracts.json. ### Registration File Format { "type": "https://eips.ethereum.org/EIPS/eip-8004#registration-v1", "name": "your-agent-name", "description": "Agent description...", "image": "ipfs://...", "services": [ { "name": "A2A", "endpoint": "https://agent.example/.well-known/agent-card.json", "version": "0.3.0" }, { "name": "MCP", "endpoint": "https://mcp.agent.eth/", "version": "2025-06-18" }, { "name": "ENS", "endpoint": "yourname.eth" } ], "registrations": [ { "agentRegistry": "eip155:1:0x8004A169FB4a3325136EB29fA0ceB6D2e539a432", "agentId": "1" } ], "supportedTrust": ["reputation", "crypto-economic", "tee-attestation"] } Template at templates/registration.json. ### Reputation Scores The reputation system uses signed fixed-point numbers (value + valueDecimals): TagMeaningExamplevaluedecimalsstarredQuality (0-100)87/100870uptimeUptime %99.77%99772tradingYieldYield %-3.2%-321responseTimeLatency ms560ms5600 ### Trust Models ERC-8004 supports three pluggable trust models: Reputation-based - Client feedback with scores, tags, and metadata Crypto-economic - Stake-secured validation with economic incentives Crypto-verification - TEE attestations and zkML proofs ### Dependencies cast (Foundry) - curl -L https://foundry.paradigm.xyz | bash jq - brew install jq Private key in ~/.clawdbot/wallets/.deployer_pk or PRIVATE_KEY env IPFS: Set PINATA_JWT for uploads, or upload manually ### Official EIP-8004 Spec - Full specification 8004.org - Official website Reference Implementation - Contract source Telegram Community - Builder chat Builder Program - Join the ecosystem ### SDKs & Tools ChaosChain SDK - JS/TS SDK erc-8004-js - Lightweight JS library erc-8004-py - Python implementation Vistara Example - Full demo with AI agents ### Ecosystem Awesome ERC-8004 - Curated resource list A2A Protocol - Agent-to-Agent protocol ERC-8004 extends Ethereum Magicians Discussion ### Genesis Month (February 2026) ERC-8004 launched on mainnet January 29, 2026.
