At small numbers it's manageable, but if we get like 50 players, it takes quite a while to send unique zaps with comments. There will be reminders about keeping zap addresses current prior to the automated payouts ☺️
Discussion
What about maybe adding a web form to the game screen where players can set their preferred lightning address for payouts? That would address the issue of people wanting their payouts to go to a different address while preserving your ability to process payouts programmatically.
Maybe I do it by sending out withdraw links instead of zaps. This would also avoid cases where people don't have an address set 🙂
