Fees
pump.fun pays a creator fee on every trade of a coin. For a PlayPost game the creator is the game's own key (derived by PlayPost's signer from its serial), so the fee lands in that key's vault.
Every 5 minutes the engine reads every game's vault (bonding curve and PumpSwap) and splits what is there: 60% to the prompter wallet bound to the serial, 20% to rooms and inference, 20% to buy and burn $PPOST. Below 0.003 SOL a vault keeps accruing.
$PPOST's own creator fees (fee route A)
$PPOST is launched with PlayPost's own creator key 9fpW4SphqgTS1kkJBZFAQkKg1RRoso684Q4drBmsNTRr, held by PlayPost's signer like the game keys, not by a personal wallet. Once the $PPOST mint is set, every 5 minutes the engine reads that key's creator vault and splits what is there: 60% to the operator wallet, 20% to rooms and inference, 20% to buy and burn $PPOST. The operator wallet is not set yet, so the vault keeps accruing until it is.

In this build the fee route runs on a mock adapter: the vault reads and the exact split transaction are real, the send is off until the vault split is proven on chain.
