Settlement & payouts
The winning snapshot, pool split, rake and rollover.
Selecting the winners
At settlement the server fetches the daily pump.fun payout board, filters it to eligible callers in the roster, and takes the first three. The resulting snapshot is stored with the round.
Round results use that snapshot rather than the board you happened to see earlier in the day. If upstream data cannot be fetched, settlement cannot be completed.
The distributable pool
The rake is 8% of new stakes in the round. Seed funds and rollover are added to the pot but are not charged that rake again.
distributable = new stakes + seed − rake on new stakes
your payout = winning-place allocation × your stake / all stakes on that caller| Place | Share of distributable pool |
|---|---|
| #1 | 50% |
| #2 | 30% |
| #3 | 20% |
Rake recipients
The holder and winning-caller portions are divided across winning places using the same place weights.
| Recipient | Share of new stakes |
|---|---|
| Winning callers' key holders | 4% |
| Winning callers | 2% |
| Protocol | 2% |
Unclaimed slices and rounding
If no one backed a winning caller, that place's distributable slice rolls into the next round. A missing eligible place also rolls over its slice. Integer payout remainder is carried forward.
