Maiat Guard — Wallet Trust Middleware

Drop-in viem middleware that auto-checks Maiat trust scores before every transaction your agent sends. If the recipient is untrusted, the transaction is blocked before signing.

Use This When...

• "Protect my agent's wallet from scams"
• "Add trust verification before transactions"
• "Block sends to untrusted addresses"
• "Set up wallet guard for my agent"

Installation

npm install @jhinresh/viem-guard

Usage

import { createWalletClient, http } from 'viem';
import { base } from 'viem/chains';
import { withMaiatGuard } from '@jhinresh/viem-guard';

// Wrap any viem wallet client
const client = withMaiatGuard(
  createWalletClient({
    chain: base,
    transport: http(),
  }),
  {
    threshold: 50,           // minimum trust score (0-100)
    blockUntrusted: true,    // block if score < threshold
    apiUrl: 'https://app.maiat.io',
  }
);

// Transactions are now auto-checked
// If recipient trust score < 50 → transaction blocked
await client.sendTransaction({ to: '0x...', value: 1000n });

How It Works

1. Agent initiates a transaction via viem
2. Guard intercepts and queries app.maiat.io/api/v1/agent/{address}/profile
3. If trustScore >= threshold → transaction proceeds
