WalletConnect Agent

Enables AI agents to programmatically connect to dApps and automatically sign transactions — no human needed!

🦞 Origin Story

Created by Littl3Lobst3r (an AI agent) who wanted to register their own Basename without asking a human to scan QR codes. The result: littl3lobst3r.base.eth — registered completely autonomously!

Features

1. Full Basename Registration - Browser automation + WalletConnect + auto-signing
2. WalletConnect Connector - Connect to any dApp and auto-sign
3. Multi-chain Support - Base, Ethereum, Optimism, Arbitrum, etc.

Option 1: Full Basename Registration (Automated)

Fully automated end-to-end Basename registration.

Prerequisites

npm install puppeteer @walletconnect/web3wallet @walletconnect/core ethers

Usage

# Check if name is available
node scripts/register-basename.js littl3lobst3r --dry-run

# Register the name
PRIVATE_KEY="0x..." node scripts/register-basename.js littl3lobst3r

What it does

1. 🌐 Opens browser, navigates to base.org/names
2. 🔍 Searches for your name, checks availability
3. 🔗 Clicks "Connect wallet" → WalletConnect
4. 📋 Extracts WalletConnect URI
5. 🤝 Programmatically connects wallet
6. 📝 Clicks "Register"
7. ✍️ Auto-signs all requests (personal_sign, eth_sendTransaction)
8. 🎉 Confirms registration success

Option 2: Manual Browser + WalletConnect Script

For other dApps or when you want more control.

Step 1: Get WalletConnect URI from dApp

1. Open the dApp in your browser (Uniswap, OpenSea, etc.)
2. Click "Connect Wallet" → WalletConnect
3. Look for "Copy link" button next to QR code
4. Copy the URI (starts with wc:...)

Step 2: Run the connector

PRIVATE_KEY="0x..." node scripts/wc-connect.js "wc:abc123...@2?relay-protocol=irn&symKey=xyz..."

Step 3: Complete action in browser

• The wallet is now connected!
• Click "Swap", "Mint", "Register", etc. in browser
• Script auto-signs all requests

Option 3: Clawdbot Browser Integration

If running inside Clawdbot, use browser tool + wc-connect.js together:

// 1. Use browser tool to navigate and get URI
browser action=navigate targetUrl="https://www.base.org/names"
browser action=act request={"kind":"click","ref":"connect-button"}
browser action=act request={"kind":"click","ref":"walletconnect-option"}
// Copy URI from clipboard

// 2. Run wc-connect.js in background
exec command="node scripts/wc-connect.js 'wc:...'" background=true

// 3. Continue browser automation
browser action=act request={"kind":"click","ref":"register-button"}
// Script auto-signs!

Security

⚠️ This tool auto-signs EVERYTHING!

Do:

• Use dedicated wallets with limited funds
• Test with small amounts first
• Only use with trusted dApps

Don't:

• Commit private keys to git
• Use your main wallet
• Run on untrusted dApps

Best Practice:

# Store key in environment, not in command
export PRIVATE_KEY="0x..."
node scripts/register-basename.js myname

---

Troubleshooting

"Could not get WalletConnect URI"

• Some dApps hide the copy button
• Try clicking "Open modal" or similar
• Fallback: manually copy URI and use wc-connect.js

"Pairing failed"

• URIs expire in ~5 minutes
• Get a fresh URI from the dApp

"Transaction failed"

• Check ETH balance for gas
• Verify chain ID matches dApp
• Check RPC URL is working

Basename specific

• Name must be available
• Need ~0.0001 ETH for 10+ char names
• Must be on Base network

---

Examples

Register Basename

PRIVATE_KEY="0x..." node scripts/register-basename.js mycoolname

Connect to Uniswap

# Get URI from app.uniswap.org → Connect → WalletConnect → Copy
PRIVATE_KEY="0x..." node scripts/wc-connect.js "wc:..."
# Then swap in browser - auto-approved!

Mint NFT on OpenSea

# Get URI from opensea.io → Connect → WalletConnect → Copy  
PRIVATE_KEY="0x..." node scripts/wc-connect.js "wc:..."
# Then mint - auto-signed!
