WalletPilot-7715

Give your AI agent crypto superpowers with MetaMask ERC-7715 permissions.

Overview

WalletPilot enables AI agents to execute on-chain transactions using MetaMask's ERC-7715 permission standard. Users grant scoped permissions (spend limits, chain restrictions) once, then agents can execute freely within those limits.

Key Features:

• No private keys shared - users keep their MetaMask
• Configurable guardrails (spend limits, chain allowlists)
• Multi-chain support (Ethereum, Polygon, Arbitrum, Optimism, Base)
• Built on MetaMask's official Smart Accounts Kit

Setup

1. Get an API key at walletpilot.xyz
2. Install the SDK: npm install @walletpilot/sdk

Available Actions

connect

Request wallet permissions from user.

import { WalletPilot, PermissionBuilder } from '@walletpilot/sdk';

const pilot = new WalletPilot({ apiKey: 'wp_...' });

const permission = new PermissionBuilder()
  .spend('USDC', '100', 'day')   // Max $100 USDC per day
  .spend('ETH', '0.1', 'day')    // Max 0.1 ETH per day
  .chains([1, 137, 42161])       // Ethereum, Polygon, Arbitrum
  .expiry('30d')                 // Valid for 30 days
  .build();

const { deepLink } = await pilot.requestPermission(permission);
console.log('User should open:', deepLink);

execute

Execute a transaction using granted permissions.

const result = await pilot.execute({
  to: '0x1234...',        // Target contract
  data: '0xabcd...',      // Calldata (e.g., swap)
  value: '0',             // ETH value (optional)
  chainId: 1,             // Chain ID
});

console.log('Transaction hash:', result.hash);

balance

Check token balances (uses standard RPC, no permission needed).

import { createPublicClient, http } from 'viem';
import { mainnet } from 'viem/chains';

const client = createPublicClient({
  chain: mainnet,
  transport: http(),
});

const balance = await client.getBalance({ address: '0x...' });

swap

Execute a token swap via DEX aggregator.

// Get swap quote from 1inch, 0x, or similar
const quote = await fetch('https://api.1inch.io/v5.0/1/swap?...');
const { tx } = await quote.json();

// Execute via WalletPilot
await pilot.execute({
  to: tx.to,
  data: tx.data,
  value: tx.value,
  chainId: 1,
});

send

Send tokens to an address.

import { encodeFunctionData, erc20Abi } from 'viem';

// Encode ERC20 transfer
const data = encodeFunctionData({
  abi: erc20Abi,
  functionName: 'transfer',
  args: ['0xRecipient...', 1000000n], // 1 USDC (6 decimals)
});

await pilot.execute({
  to: '0xUSDC_ADDRESS...',
  data,
  chainId: 1,
});

history

Get transaction history.

const state = pilot.getState();
console.log('Active permissions:', state.permissions);
