RSVP with a deposit.
Show up and it comes back.

Two hundred people RSVP and sixty turn up. A refundable deposit fixes that. Flake, and your deposit goes to the people who came.

The contract pays out

Everyone who came gets their deposit back plus a share of what the no-shows left. Anyone can recheck the maths.

The deposits sit in a contract on Base the whole time. Nobody can spend them, which is what lets you take money from your friends without ever holding it.
