Important: Two Solana Wallets

ClawVault uses two separate Solana wallets:

• Main Vault (Crossmint smart wallet) — For crypto payments and token swaps
• Payment Wallet (standalone Solana keypair) — For prediction market trades only

Swaps use the main vault. Predictions use the payment wallet. They must be funded separately. Set up the payment wallet at the /predictions page in your dashboard.

How It Works

1. You ask Claude to pay for something
2. Claude uses request_payment tool
3. ClawVault checks your rules:
   • Within rules → auto-approved, payment executes
   • Outside rules → pending, you get a Telegram/dashboard notification
4. You approve or deny from Telegram or the web dashboard
5. Claude gets the result
