Fees
A flat 1% on every bet.
Every bet pays a 1% fee, in practice and real mode. Bet 1 SOL and 0.99 SOL goes into the pool.
The fee is taken when you bet, not when you win. It is kept even if a pool is refunded.
There are no other fees from Polymeme. Real mode bets also pay a tiny Solana network fee to your wallet's network.
