Wallet API

Both the wallet and server use JSON-RPC over the same endpoint.

CLI commands accept an optional --wallet parameter to specify which wallet to use. If not specified, it defaults to default.

RPC commands differ from their CLI counterparts due to legacy compatibility reasons. This may be harmonized in future releases.
