Hardware wallet support

Goal

Connect a hardware wallet to the MoonPay CLI. Private keys never leave the device — the CLI stores only cached addresses. All existing commands (swap, transfer, bridge, buy, balance) work transparently with hardware wallets.

First supported device: Ledger (Nano S, Nano X, Nano S Plus, Stax, Flex).

Prerequisites

• Ledger device connected via USB
• Ledger Live installed (for firmware updates)
• Ethereum and/or Solana apps installed on the device
