Brewit Crypto Skill

A skill for performing cryptocurrency transactions using Brewit smart accounts with account abstraction on Base network.

Installation

1. Install dependencies:

   npm install brewit viem

2. Get Pimlico API key:

   • Sign up at https://pimlico.io
   • Get your API key (starts with pim_)

3. Load the skill:

   • Copy this folder to your OpenClaw skills directory
   • The agent will automatically detect and use it when needed

What This Skill Does

• Create Brewit smart accounts
• Send USDC and ETH (gasless!)
• Batch transactions to multiple recipients
• Check token balances
• Resolve ENS names

Quick Start Scripts

Create Account

node scripts/create-account.js 0xYourPrivateKey

Check Balance

node scripts/check-balance.js 0xSmartAccountAddress

Send USDC

node scripts/send-usdc.js 0xPrivateKey 0xRecipient 0.1 pim_YourAPIKey

Batch Send

node scripts/batch-send.js 0xPrivateKey pim_APIKey 0xAddr1:0.1 0xAddr2:0.2

How It Works

1. Smart Accounts: Uses Brewit (ERC-4337) for smart contract wallets
2. Gasless: Pimlico bundler sponsors gas fees
3. Batch: Send to multiple addresses in one transaction
4. Base Network: Optimized for Base L2 (low fees, fast)

Security

• Never commit private keys to git
• Use environment variables for sensitive data
• Test on testnet first (Base Sepolia)
• Double-check recipient addresses
