The rules

One set of rules for every coin. Version 1. Any change is announced here first and only applies from the round after it is posted.

Rounds

Every coin pays every 10 minutes, on the clock (:00, :10, :20…). Each round shares the SOL that arrived in the coin's vault since the last one, plus anything forfeited.

Your share

Your share of a round is your bag times its multiplier, counted second by second across the 10 minutes. A buy in the last second of a round earns almost nothing; holding through the whole round earns the most.

The multiplier

Every buy has its own clock. It starts at 1x and climbs +1x every hour to 5x, then +1x every day to 10x.

Fees

That is the split of each coin's creator fee, which pump.fun sets at 0.3% of every trade on SOL pairs. It is written into the launch transaction with the admin revoked, so it can never change.
