🔐 Base Wallet - Crypto Identity for AI Agents

Every autonomous agent needs a wallet. Create one without human help.

TL;DR: Programmatic wallet creation on Base/Ethereum. SIWE auth, balance checks, transactions.

Why Base Wallet?

True autonomy — Your agent creates and controls its own wallet
No browser needed — Pure CLI, no extensions or popups
SIWE ready — Sign-In with Ethereum for Web3 services
Secure by default — Environment variables, no plaintext keys

Create and manage Base chain (Ethereum-compatible) wallets programmatically.

⚠️ Security First

✅ DO	❌ DON'T
Use environment variables for private keys	Store private keys in plain text files
Set wallet files to chmod 600	Commit wallet files to git
Use `--env` mode (recommended)	Use `console.log(privateKey)`
Back up mnemonics offline	Share private keys or mnemonics

Quick Start

Create a New Wallet (Recommended)

# Output as environment variable format (safest)
node scripts/create-wallet.js --env

# Output example:
# export WALLET_ADDRESS="0x..."
# export PRIVATE_KEY="0x..."

Then copy to your shell or .env file.

Create with File Storage (Opt-in)

# Only if you need file-based storage
node scripts/create-wallet.js --managed my-agent

⚠️ This stores private key in ~/.openclaw/wallets/my-agent.json

Usage Examples

Load Wallet from Environment

const { ethers } = require('ethers');

// ✅ SECURE: Load from environment variable
const wallet = new ethers.Wallet(process.env.PRIVATE_KEY);
console.log('Address:', wallet.address);
// ❌ NEVER: console.log('Private Key:', wallet.privateKey);

Load from Mnemonic

const wallet = ethers.Wallet.fromPhrase(process.env.MNEMONIC);

Check Balance

const provider = new ethers.JsonRpcProvider('https://mainnet.base.org');
const balance = await provider.getBalan...
