Every buy and sell of $SLICE on pump.fun pays a 3 % creator fee in $PUMP. The creator is the pizza wallet, and it collects the fee every round.
Each round, 10 % of the pizza goes to the wallets that mined in it, split by the work they did. Small amounts wait and are paid when they grow.
Every 10th round the whole slice goes to one miner, drawn from a Solana block that did not exist when the tickets were fixed.
Each payout carries a memo with the round number and the hash of the round file. Open the last round file or the pizza wallet on Solscan.
