Walletconnect Requester

WalletConnect Requester

Zero custody. Maximum security. User always in control.

Why This Skill?

Unlike walletconnect-agent which holds private keys and auto-signs, this skill takes a fundamentally different approach:

This is the safest way for AI agents to interact with Web3.

What This Does

• Connect to user wallets via WalletConnect v2
• Request transactions - user approves in their wallet
• Request signatures - user signs in their wallet
• Zero private key exposure - keys never leave the user's wallet

Installation

Step 1: Install Dependencies

This skill requires Node.js dependencies. Install them globally or locally:

# Install dependencies
npm install @walletconnect/sign-client @walletconnect/core qrcode

Step 2: Get WalletConnect Project ID

1. Go to WalletConnect Cloud
2. Create a new project
3. Copy your Project ID

Step 3: Set Environment Variable

export WC_PROJECT_ID="your_project_id_here"

Step 4: Run the Skill

node scripts/wc-requester.js connect

Quick Start

Step 1: Create a Session

export WC_PROJECT_ID="your_project_id"
node scripts/wc-requester.js connect

Output:

WalletConnect URI: wc:abc123...@2?relay-protocol=irn&symKey=xyz

Scan this QR code with your wallet:
[QR CODE]

Waiting for wallet to connect...

Step 2: Request a Transaction

node scripts/wc-requester.js request-tx \
  --to 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 \
  --data 0xa9059cbb... \
  --value 0 \
  --chain 8453

User sees in wallet:

Send 10 USDC to 0x1F3A...?
[Approve] [Reject]

Step 3: Request a Signature

node scripts/wc-requester.js request-sign \
  --message "Sign this message to verify ownership" \
  --chain 8453

Commands

connect - Create WalletConnect Session

node scripts/wc-requester.js connect [options]

Options:
  --chains <ids>     Comma-separated chain IDs (default: 8453,1)
  --methods <list>   Comma-separated methods (default: eth_sendTransaction,personal_sign)
  --qr <path>        Generate QR code to file
  --json             Output as JSON

request-tx - Request Transaction

node scripts/wc-requester.js request-tx --to <address> --data <hex> --value <wei> --chain <id>

request-sign - Request Signature

node scripts/wc-requester.js request-sign --message <text> --chain <id>
# or for typed data
node scripts/wc-requester.js request-sign --typed-data <json> --chain <id>

sessions - List Active Sessions

node scripts/wc-requester.js sessions

disconnect - End Session

node scripts/wc-requester.js disconnect --topic <topic>

Security Model

What Agent CAN Do

• ✅ Request transactions (user must approve)
• ✅ Request signatures (user must approve)
• ✅ View connected wallet address
• ✅ View session metadata

What Agent CANNOT Do

• ❌ Hold private keys
• ❌ Auto-sign anything
• ❌ Execute transactions without approval
• ❌ Access funds directly

If Agent is Compromised

• ✅ Attacker cannot steal funds (no keys)
• ✅ Attacker cannot auto-sign transactions
• ✅ User can reject any suspicious request
• ✅ User can disconnect session anytime

Local Data Persistence

This skill writes files to ~/.walletconnect-requester/:

Security recommendations:

• Review audit.log before sharing
• Delete sessions.json when no longer needed
• Set appropriate file permissions: chmod 600 ~/.walletconnect-requester/*

Sensitive Data Handling

Privacy Considerations

• WalletConnect URI (with symKey) is printed to stdout for QR code generation
• Audit logs mask full addresses (e.g., 0x8335... instead of full address)
• No data is sent to external servers except WalletConnect relay network

Configuration

Environment Variables

Namespaces Configuration

The skill requests minimal permissions by default:

{
  "eip155": {
    "chains": ["eip155:8453", "eip155:1"],
    "methods": ["eth_sendTransaction", "personal_sign"],
    "events": ["accountsChanged", "chainChanged"]
  }
}

Example Workflows

Connect and Request Payment

# 1. Create session
node scripts/wc-requester.js connect --qr /tmp/qr.png
# User scans QR with MetaMask

# 2. Request USDC transfer
node scripts/wc-requester.js request-tx \
  --to 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 \
  --data 0xa9059cbb0000... \
  --chain 8453

# User sees: "Send 10 USDC?" → Approves in wallet
# Returns: tx_hash

Verify Wallet Ownership

# 1. Connect
node scripts/wc-requester.js connect

# 2. Request signature
node scripts/wc-requester.js request-sign \
  --message "I own this wallet on March 9, 2026"

# User signs in wallet
# Returns: signature

Comparison with Other Solutions

Supported Wallets

Any wallet that supports WalletConnect v2:

• MetaMask Mobile
• Rainbow
• Trust Wallet
• Coinbase Wallet
• Ledger Live
• And 500+ more...

Troubleshooting

"No active session"

Run connect first to create a session.

"User rejected request"

User declined in their wallet. Ask if they want to retry.

"Session expired"

Sessions last 7 days by default. Reconnect to create a new session.

"Unsupported chain"

User's wallet doesn't support the requested chain. Ask them to switch networks.

Audit Log

All requests are logged (without sensitive data):

~/.walletconnect-requester/audit.log

{
  "timestamp": "2026-03-09T02:00:00Z",
  "action": "request_transaction",
  "chain": 8453,
  "to": "0x8335...",
  "status": "approved",
  "tx_hash": "0xabc123..."
}

When to Use This vs walletconnect-agent

When in doubt, use this skill. It's always safer.
