Full spec: references/spec.md
agent0-sdk)Three lightweight registries, each deployed as a UUPS-upgradeable singleton:
| Registry | Purpose | Contract |
|---|---|---|
| Identity | ERC-721 NFTs for agent identities + registration files | IdentityRegistryUpgradeable |
| Reputation | Signed fixed-point feedback signals + off-chain detail files | ReputationRegistryUpgradeable |
| Validation | Third-party validator attestations (stake, zkML, TEE) | ValidationRegistryUpgradeable |
Agent identity = agentRegistry (string eip155:{chainId}:{contractAddress}) + agentId (ERC-721 tokenId).
Each agent's agentURI points to a JSON registration file (IPFS or HTTPS) advertising name, description, endpoints (MCP, A2A, ENS, DID, wallet), OASF skills/domains, trust models, and x402 support.
See: references/contracts.md for full contract interfaces and addresses.
npm install agent0-sdk
RPC_URL, PRIVATE_KEY, and PINATA_JWT are declared in this skill's metadata.openclaw.envVars. Use throwaway/testnet keys for development; reach for a hardware wallet or scoped signer for any mainnet activity.
import { SDK } from 'agent0-sdk';
const sdk = new SDK({
chainId: 84532, // Base Sepolia
rpcUrl: process.env.RPC_URL,
privateKey: process.env.PRIVATE_KEY,
ipfs: 'pinata',
pinataJwt: process.env.PINATA_JWT,
});
const agent = sdk.createAgent(
'MyAgent',
'An AI agent that analyzes crypto markets',
'https://example.com/agent-image.png'
);
// Configure endpoints and capabilities
await agent.setMCP('https://mcp.example.com', '2025-06-18', true); // auto-fetches tools

agent.addDomain('finance_and_business/investment_services', true);
// Register on-chain (mints NFT + uploads to IPFS).
// Sends a real transaction signed with PRIVATE_KEY - confirm chainId, signer, and balance before running.
const tx = await agent.registerIPFS();
const { result } = await tx.waitConfirmed();
console.log(`Registered: ${result.agentId}`); // e.g. "84532:42"
const sdk = new SDK({ chainId: 84532, rpcUrl: process.env.RPC_URL });
// Search by capabilities
const agents = await sdk.searchAgents({
hasMCP: true,

x402support: true,
mcpTools: ['financial_analyzer'],
supportedTrust: ['reputation'],
});
// Get a specific agent
const agent = await sdk.getAgent('84532:42');
// Semantic search
const results = await sdk.searchAgents(
{ keyword: 'crypto market analysis' },
{ sort: ['semanticScore:desc'] }
);
// Prepare optional off-chain feedback file
const feedbackFile = await sdk.prepareFeedbackFile({
text: 'Accurate market analysis',
capability: 'tools',
name: 'financial_analyzer',
proofOfPayment: { txHash: '0x...', chainId: '8453', fromAddress: '0x...', toAddress: '0x...' },
});
// Submit feedback (value=85 out of 100). On-chain tx; same caveats as `registerIPFS()` above.
const tx = await sdk.giveFeedback('84532:42', 85, 'starred', '', '', feedbackFile);
await tx.waitConfirmed();
// Read reputation summary
const summary = await sdk.getReputationSummary('84532:42');
console.log(`Average: ${summary.averageValue}, Count: ${summary.count}`);
See: references/sdk-typescript.md for full SDK API reference.
Every agent's agentURI resolves to this JSON structure:
{
"type": "https://eips.ethereum.org/EIPS/eip-8004#registration-v1",
"name": "MyAgent",
"description": "What it does, pricing, interaction methods",

],
"supportedTrust": ["reputation", "crypto-economic", "tee-attestation"],
"active": true,
"x402Support": true
}
The registrations field creates a bidirectional cryptographic link: the NFT points to this file, and this file points back to the NFT. This enables endpoint domain verification via /.well-known/agent-registration.json.
See: references/registration.md for best practices (Four Golden Rules) and complete field reference.
All registries deploy to deterministic vanity addresses via CREATE2 (SAFE Singleton Factory):
| Registry | Address |

Same proxy addresses on: Ethereum, Base, Arbitrum, Avalanche, Celo, Gnosis, Linea, Mantle, MegaETH, Optimism, Polygon, Scroll, Taiko, Monad, BSC + testnets.
Feedback uses signed fixed-point numbers: value (int128) + valueDecimals (uint8, 0-18).
| tag1 | Measures | Example | value | valueDecimals |
|---|---|---|---|---|
starred | Quality 0-100 | 87/100 | 87 | 0 |
reachable | Endpoint up (binary) | true | 1 | 0 |
uptime | Uptime % | 99.77% | 9977 | 2 |
successRate | Success % | 89% | 89 | 0 |
responseTime | Latency ms | 560ms | 560 | 0 |
Anti-Sybil: getSummary() requires a non-empty clientAddresses array (caller must supply trusted reviewer list). Self-feedback is rejected (agent owner/operators cannot submit feedback on their own agent).
See: references/reputation.md for full feedback system, off-chain file format, and aggregation details.
Open Agentic Schema Framework provides standardized skills (136) and domains (204) for agent classification.
Top-level skill categories: natural_language_processing, images_computer_vision, audio, analytical_skills, multi_modal, agent_orchestration, advanced_reasoning_planning, data_engineering, security_privacy, evaluation_monitoring, devops_mlops, governance_compliance, tool_interaction, retrieval_augmented_generation, tabular_text

# 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` |
| **Reputation** | Signed fixed-point feedback signals + off-chain detail files | `ReputationRegistryUpgradeable` |
| **Validation** | Third-party validator attestations (stake, zkML, TEE) | `ValidationRegistryUpgradeable` |
**Agent identity** = `agentRegistry` (string `eip155:{chainId}:{contractAddress}`) + `agentId` (ERC-721 tokenId).
Each agent's `agentURI` points to a JSON registration file (IPFS or HTTPS) advertising name, description, endpoints (MCP, A2A, ENS, DID, wallet), OASF skills/domains, trust models, and x402 support.
**See:** [references/contracts.md](references/contracts.md) for full contract interfaces and addresses.
## Quick Start with Agent0 SDK (TypeScript)
```bash
npm install agent0-sdk
```
### Register an Agent
`RPC_URL`, `PRIVATE_KEY`, and `PINATA_JWT` are declared in this skill's `metadata.openclaw.envVars`. Use throwaway/testnet keys for development; reach for a hardware wallet or scoped signer for any mainnet activity.
```typescript
import { SDK } from 'agent0-sdk';
const sdk = new SDK({
chainId: 84532, // Base Sepolia
rpcUrl: process.env.RPC_URL,
privateKey: process.env.PRIVATE_KEY,
ipfs: 'pinata',
pinataJwt: process.env.PINATA_JWT,
});
const agent = sdk.createAgent(
'MyAgent',
'An AI agent that analyzes crypto markets',
'https://example.com/agent-image.png'
);
// Configure endpoints and capabilities
await agent.setMCP('https://mcp.example.com', '2025-06-18', true); // auto-fetches tools
await agent.setA2A('https://example.com/.well-known/agent-card.json', '0.3.0', true);
agent.setENS('myagent.eth');
agent.setActive(true);
agent.setX402Support(true);
agent.setTrust(true, false, false); // reputation only
// Add OASF taxonomy
agent.addSkill('natural_language_processing/natural_language_generation/summarization', true);
agent.addDomain('finance_and_business/investment_services', true);
// Register on-chain (mints NFT + uploads to IPFS).
// Sends a real transaction signed with PRIVATE_KEY - confirm chainId, signer, and balance before running.
const tx = await agent.registerIPFS();
const { result } = await tx.waitConfirmed();
console.log(`Registered: ${result.agentId}`); // e.g. "84532:42"
```
### Search for Agents
```typescript
const sdk = new SDK({ chainId: 84532, rpcUrl: process.env.RPC_URL });
// Search by capabilities
const agents = await sdk.searchAgents({
hasMCP: true,
active: true,
x402support: true,
mcpTools: ['financial_analyzer'],
supportedTrust: ['reputation'],
});
// Get a specific agent
const agent = await sdk.getAgent('84532:42');
// Semantic search
const results = await sdk.searchAgents(
{ keyword: 'crypto market analysis' },
{ sort: ['semanticScore:desc'] }
);
```
### Give Feedback
```typescript
// Prepare optional off-chain feedback file
const feedbackFile = await sdk.prepareFeedbackFile({
text: 'Accurate market analysis',
capability: 'tools',
name: 'financial_analyzer',
proofOfPayment: { txHash: '0x...', chainId: '8453', fromAddress: '0x...', toAddress: '0x...' },
});
// Submit feedback (value=85 out of 100). On-chain tx; same caveats as `registerIPFS()` above.
const tx = await sdk.giveFeedback('84532:42', 85, 'starred', '', '', feedbackFile);
await tx.waitConfirmed();
// Read reputation summary
const summary = await sdk.getReputationSummary('84532:42');
console.log(`Average: ${summary.averageValue}, Count: ${summary.count}`);
```
**See:** [references/sdk-typescript.md](references/sdk-typescript.md) for full SDK API reference.
## Registration File Format
Every agent's `agentURI` resolves to this JSON structure:
```json
{
"type": "https://eips.ethereum.org/EIPS/eip-8004#registration-v1",
"name": "MyAgent",
"description": "What it does, pricing, interaction methods",
"image": "https://example.com/agent.png",
"services": [
{ "name": "MCP", "endpoint": "https://mcp.example.com", "version": "2025-06-18", "mcpTools": ["tool1"] },
{ "name": "A2A", "endpoint": "https://example.com/.well-known/agent-card.json", "version": "0.3.0" },
{ "name": "OASF", "endpoint": "https://github.com/agntcy/oasf/", "version": "v0.8.0",
"skills": ["natural_language_processing/summarization"],
"domains": ["finance_and_business/investment_services"] },
{ "name": "ENS", "endpoint": "myagent.eth", "version": "v1" },
{ "name": "agentWallet", "endpoint": "eip155:8453:0x..." }
],
"registrations": [
{ "agentId": 42, "agentRegistry": "eip155:84532:0x8004A818BFB912233c491871b3d84c89A494BD9e" }
],
"supportedTrust": ["reputation", "crypto-economic", "tee-attestation"],
"active": true,
"x402Support": true
}
```
The `registrations` field creates a bidirectional cryptographic link: the NFT points to this file, and this file points back to the NFT. This enables endpoint domain verification via `/.well-known/agent-registration.json`.
**See:** [references/registration.md](references/registration.md) for best practices (Four Golden Rules) and complete field reference.
## Contract Addresses
All registries deploy to deterministic vanity addresses via CREATE2 (SAFE Singleton Factory):
### Mainnet (Ethereum, Base, Polygon, Arbitrum, Optimism, etc.)
| Registry | Address |
|----------|---------|
| Identity | `0x8004A169FB4a3325136EB29fA0ceB6D2e539a432` |
| Reputation | `0x8004BAa17C55a88189AE136b182e5fdA19dE9b63` |
| Validation | `0x8004Cb1BF31DAf7788923b405b754f57acEB4272` |
### Testnet (Sepolia, Base Sepolia, etc.)
| Registry | Address |
|----------|---------|
| Identity | `0x8004A818BFB912233c491871b3d84c89A494BD9e` |
| Reputation | `0x8004B663056A597Dffe9eCcC1965A193B7388713` |
| Validation | `0x8004Cb1BF31DAf7788923b405b754f57acEB4272` |
Same proxy addresses on: Ethereum, Base, Arbitrum, Avalanche, Celo, Gnosis, Linea, Mantle, MegaETH, Optimism, Polygon, Scroll, Taiko, Monad, BSC + testnets.
## Reputation System
Feedback uses signed fixed-point numbers: `value` (int128) + `valueDecimals` (uint8, 0-18).
| tag1 | Measures | Example | value | valueDecimals |
|------|----------|---------|-------|---------------|
| `starred` | Quality 0-100 | 87/100 | 87 | 0 |
| `reachable` | Endpoint up (binary) | true | 1 | 0 |
| `uptime` | Uptime % | 99.77% | 9977 | 2 |
| `successRate` | Success % | 89% | 89 | 0 |
| `responseTime` | Latency ms | 560ms | 560 | 0 |
Anti-Sybil: `getSummary()` requires a non-empty `clientAddresses` array (caller must supply trusted reviewer list). Self-feedback is rejected (agent owner/operators cannot submit feedback on their own agent).
**See:** [references/reputation.md](references/reputation.md) for full feedback system, off-chain file format, and aggregation details.
## OASF Taxonomy (v0.8.0)
Open Agentic Schema Framework provides standardized skills (136) and domains (204) for agent classification.
**Top-level skill categories:** `natural_language_processing`, `images_computer_vision`, `audio`, `analytical_skills`, `multi_modal`, `agent_orchestration`, `advanced_reasoning_planning`, `data_engineering`, `security_privacy`, `evaluation_monitoring`, `devops_mlops`, `governance_compliance`, `tool_interaction`, `retrieval_augmented_generation`, `tabular_text`
**Top-level domain categories:** `technology`, `finance_and_business`, `healthcare`, `legal`, `education`, `life_science`, `agriculture`, `energy`, `environmental_science`, `government`, `manufacturing`, `transportation`, and more.
Use slash-separated paths: `agent.addSkill('natural_language_processing/natural_language_generation/summarization', true)`.
