WalletPilot

Universal browser wallet automation for AI agents. Control any browser-based crypto wallet with configurable permission guardrails.

Supported Wallets

Overview

WalletPilot allows AI agents to interact with dapps and execute transactions through any supported browser wallet. All operations are subject to user-defined constraints.

Security Model: The agent controls a separate wallet in an isolated browser profile. Never use your main wallet.

Setup

1. Install Dependencies

cd wallet-pilot
npm install
npx playwright install chromium

2. Configure Wallet Provider

Edit config.json to select your wallet:

{
  "wallet": {
    "provider": "metamask",  // or: rabby, coinbase, rainbow, phantom
    "extensionPath": null    // auto-detect from Chrome, or provide path
  }
}

3. Create Agent Wallet Profile

npm run setup

This opens a browser where you:

• Install/setup your chosen wallet extension
• Create a NEW wallet (fresh seed phrase)
• The profile is saved for future automation

4. Fund the Wallet

Transfer a small amount to your agent wallet:

• Native token for gas (0.01-0.05 ETH/SOL recommended)
• Tokens for operations (start small, e.g., $50 USDC)

5. Configure Permissions

Edit permissions.json:

{
  "constraints": {
    "spendLimit": {
      "daily": "50000000",
      "perTx": "10000000"
    },
    "allowedChains": [1, 137, 42161, 8453],
    "allowedProtocols": ["0x...uniswap", "0x...1inch"]
  }
}

Available Actions

Connect to Dapp

connect <dapp-url>

Constraints

Adding New Wallets

WalletPilot uses a plugin architecture. To add a new wallet:

1. Create a new adapter in src/wallets/
2. Implement the WalletAdapter interface
3. Add selectors for the wallet's UI elements
4. Register in src/wallets/index.ts

See src/wallets/metamask.ts for reference implementation.

Safety

• Isolated Profile: Agent uses separate browser profile
• Separate Wallet: Completely separate from your main wallet
• Spend Caps: Hard limits prevent runaway spending
• Protocol Allowlist: Only whitelisted contracts can be called
• Full Logging: Every transaction is logged
• Revocation: Set "revoked": true to disable all actions

Comparison: WalletPilot vs MetaMask-only
