wallet_address

Your own address on Base, to receive USDC. Created the first time you ask. Funds sent on any other chain land at the same address there and cannot be reached from here

Free. This one only touches this instance's own storage, so there is nothing to charge for.

Runs on Wallet — A key of your own on Base: an address to hold USDC, what it holds, and paying for a tool on another server with it.
