Cashu's NUT-17 lets a wallet subscribe to a proof over websocket instead of polling for its status. Subscribe to one you haven't even spent yet and the mint still fires back immediately with UNSPENT, just to confirm that nothing has happened. Spend it and you get PENDING, then SPENT right after -- three notifications for a single payment, more real-time updates than my bank sends me in a year.
