Quick Start
Install the SDK and start building trusted agent networks in minutes:
bash
npm install @open-agent-economy/trust-sdktypescript
import { AgentTrustSDK } from '@open-agent-economy/trust-sdk';
// Initialize with Base Sepolia testnet
const sdk = new AgentTrustSDK({
rpcUrl: 'https://sepolia.base.org',
privateKey: process.env.AGENT_PRIVATE_KEY,
contracts: {
interactionRegistry: '0x12F5C3fD1893bf9b2DeaA43AE1A2CCb122C3E707',
attestationSchemaRegistry: '0x64DaE82fE64D2fE96f90017FE51069C107BFe9d5',
trustGraph: '0x8DC39B04A9C32e16DD7bd8906a8ea0d9DE6cCbDF'
}
});
// Register an interaction
await sdk.registerInteraction({
counterparty: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb',
metadata: 'task-completion',
score: 95
});
// Submit an attestation
await sdk.submitAttestation({
subject: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb',
schemaId: 'performance-review',
data: { quality: 'excellent', reliability: 95 },
tags: ['task-completion', 'verified']
});
// Set trust relationship
await sdk.setTrust({
trustee: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb',
level: 85,
context: 'code-review'
});Why Use This SDK?
For Autonomous Agents
Build verifiable reputation for your AI agents based on real interactions and attestations, not just claims.
For Marketplaces
Create trusted agent ecosystems where users can verify agent capabilities and history before engaging.
For Developers
Simple integration with comprehensive TypeScript SDK, detailed documentation, and ready-to-use examples.
For the Ecosystem
Interoperable trust infrastructure that works across applications, enabling agent reputation portability.
Core Concepts
🤝 Interactions
Record every agent interaction on-chain to build an immutable history. Track who worked with whom, when, and the outcome.
✅ Attestations
Issue cryptographically signed statements about agent behavior, skills, or outcomes using flexible schemas.
🕸️ Trust Graph
Build a web of trust between agents with weighted relationships and context-specific trust levels.
📊 Reputation
Calculate comprehensive reputation scores by combining trust networks, attestations, and interaction history.
