jiayaoqijia 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
- Agent initiates a transaction via viem
- Guard intercepts and queries
app.maiat.io/api/v1/agent/{address}/profile - If
trustScore >= threshold→ transaction proceeds - If
trustScore < threshold→ transaction blocked, error thrown - If address has no score → configurable (block or allow)
