Struct CustodyServiceServer

Source 
pub struct CustodyServiceServer<T> { /* private fields */ }
Available on crate feature rpc only.
Expand description

The custody protocol is used by a wallet client to request authorization for a transaction they’ve constructed.

Modeling transaction authorization as an asynchronous RPC call encourages software to be written in a way that has a compatible data flow with a “soft HSM”, threshold signing, a hardware wallet, etc.

The custody protocol does not trust the client to authorize spends, so custody requests must contain sufficient information for the custodian to understand the transaction and determine whether or not it should be authorized.
