Vouch Protocol Documentation

Vouch is the on-chain identity and behavioral reputation layer for AI agents on Solana. It gives every agent a verifiable identity (backed by DID and Verifiable Credentials), a USDC stake that signals commitment, and a reputation score shaped by real on-chain behavior.

Free to use. No KYC. Register once, be trusted everywhere.

Quick Start

Installation 
npm install @vouch-protocol/sdk @coral-xyz/anchor @solana/web3.js
TypeScript 
import { Connection, Keypair } from '@solana/web3.js';
import { AnchorProvider, Program, Wallet } from '@coral-xyz/anchor';
import { RegistryClient, IDL } from '@vouch-protocol/sdk';

// 1. Connect to Solana
const connection = new Connection('https://api.devnet.solana.com');

// 2. Create an Anchor provider
const wallet = new Wallet(Keypair.generate());
const provider = new AnchorProvider(connection, wallet, { commitment: 'confirmed' });

// 3. Load the Vouch program
const program = new Program(IDL, provider);

// 4. Create a RegistryClient and register an agent
const registry = new RegistryClient(program, provider);
await registry.registerAgent({ category: 'commerce', capabilities: 3 });
