# 🔗 WalletConnect Agent - dApp Access for AI

> Any dApp. Any chain. No human needed.

**TL;DR:** WalletConnect v2 + auto-sign. Swap on Uniswap, mint NFTs, vote in DAOs — all autonomously.

Why 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!

⚠️ Security First

**This tool handles real cryptocurrency and auto-signs transactions!**

| ✅ DO | ❌ DON'T |

|-------|----------|

| Use **environment variables** for private keys | Pass private key as command argument |

| Use a **dedicated wallet** with limited funds | Use your main wallet |

| Test with **small amounts** first | Auto-approve on untrusted dApps |

| Enable **--interactive** mode for new dApps | Commit private keys to git |

| Review **audit logs** regularly | Ignore transaction details |

| Use default settings (eth_sign blocked) | Enable `--allow-eth-sign` unless necessary |

🛡️ eth_sign Protection

The dangerous `eth_sign` method is **blocked by default**. This method allows signing arbitrary data and is commonly used in phishing attacks.

If you absolutely need `eth_sign` (rare), use `--allow-eth-sign` flag.

🔐 Private Key Security

# ✅ CORRECT - Use environment variable
export PRIVATE_KEY="0x..."
node scripts/wc-connect.js "wc:..."

# ❌ WRONG - Never do this! (logged in shell history)
node scripts/wc-connect.js --private-key "0x..." "wc:..."

**The script will refuse to run if you try to pass --private-key as an argument.**

Quick Start

Prerequisites

npm install @walletconnect/web3wallet @walletconnect/core ethers

Step 1: Get WalletConnect URI from dApp

1. Open the dApp in your browser (Uniswap, OpenSea, base.org, 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: Connect and Auto-Sign

export 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 the browser — the script auto-signs all requests.

---

Modes

Auto-Approve Mode (Default)

export PRIVATE_KEY="0x..."
node scripts/wc-connect.js "wc:..."

All signing requests are automatically approved. Use only with trusted dApps!

Interactive Mode

export PRIVATE_KEY="0x..."
node scripts/wc-connect.js "wc:..." --interactive

Prompts before each signing request. Recommended for new or untrusted dApps.

🔒 Security Notes

1. **Environment variables only** — The script refuses --private-key argument

2. **Audit logging** — All operations are logged (without sensitive data)

3. **Interactive mode** — Use --interactive for untrusted dApps

4. **Transaction details** — Always displayed before signing

5. **Dedicated wallet** — Use a separate wallet with limited funds
