Give your AI agent crypto superpowers with MetaMask ERC-7715 permissions.
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:
npm install @walletpilot/sdkRequest 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 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);
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...' });
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 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,
});
Get transaction history.
const state = pilot.getState();
console.log('Active permissions:', state.permissions);
// Or via API
const response = await fetch('https://api.walletpilot.xyz/v1/tx/history/PERMISSION_ID', {
headers: { 'Authorization': 'Bearer wp_...' },
});
const { data } = await response.json();
console.log('Recent transactions:', data);
