Sign-time risk verdict for a destination or spender before value moves
Sign-time risk verdict for a destination or spender before value moves. Registry + ScamDB lookups plus at most one RPC call (approve spender code check), so it answers in milliseconds instead of running a full scan. Same verdict as the subscription REST API.
