MoonPay Integration

The skill uses local signing paths for execution. vaults.fyi returns unsigned calldata only and never receives private keys. Workflow:

1. mp wallet create to set up a vaults agent wallet
2. mp buy or mp token bridge to fund the wallet
3. vaults.fyi MCP returns unsigned EVM transaction steps (approve, deposit, claim, redeem)
4. Agent shows the MCP human approval checkpoint and waits for confirmation
5. mp transaction prepare, mp transaction sign, then mp transaction send to broadcast

For ERC-4337 smart wallets, the skill routes through OWS or the browser fallback instead of the MoonPay CLI EOA transaction path.

Example Usage

User asks: "Find me the highest reputation USDC vault on Base and deposit 10,000."
