Trading fees & holder rewards
Where trading fees go, and how key holders share them.
Current trading fee split
The total fee is 10% of the base curve amount on both buys and sells. The components below are percentages of the base amount, not percentages of the fee.
| Recipient | Share of base amount |
|---|---|
| Caller | 5% |
| Key holders | 3% |
| Protocol | 2% |
How the holder share is allocated
A holder distribution is divided in proportion to eligible keys. Buy fees use holdings before the purchase; sell fees use holdings after the sale. Round rake uses holdings at settlement. Someone holding twice as many eligible keys receives twice the share before integer rounding.
Rewards are credited to the internal ledger and appear in My Book. They are not automatically sent as separate wallet transfers. Rounding and situations with no eligible holders are handled by the protocol's distribution logic.
Separate reward sources
Trading fee credits and Daily Call rake credits are separate ledger entries. Winning a prediction is a third source of balance credits.
A caller's dollar payout on pump.fun is an external statistic. Callbook does not directly divide that external payout among key holders.
