The rules
Every five minutes six pump.fun coins run as unicorns. Best average price wins. Backers of the winner share the pool. Real numbers from the program below.
- 1
The field
Up to six migrated pump.fun coins with real trade: cap 300 SOL+, 20 SOL volume in 5 min, trades in 24 of 30 windows, pool 80 SOL+. Booked lanes go first.
- 2
Bets
In $DERBY, from the open to the off, closed on chain. Min 1,000. Stakes sit in a vault owned by the race account.
- 3
The race
30 windows of 10 s. Each stores every runner's pool price, clamped to 25% from its last one. Score = mean of snapshots / first snapshot.
- 4
The judge
Highest score wins with 20+ windows sampled. No start price or too few snapshots: scratched, refunded. Under two runners, a dead heat or nobody on the winner: void, all refunded.
- 5
Pay
90% winning tickets by stake, 5% dev of the winning coin (no plain dev wallet: to the tickets), 5% platform. Claim any time; the keeper also pushes payouts.
PAYS = POOL x 90% / MONEY ON THE WINNER
Odds move until the off. Everyone on the winner gets 90% back. It's a tote, not a bug.
Nobody can
Touch your stake
It sits in the race vault. Only the program pays out.
Change the field
Final at the open. The keeper too.
Switch the coin
The bet coin is set once, locked forever.
Stall a race
Sample, settle and claim are open to anyone.
Keep a lane fee
Coin not run: anyone refunds it.
Pump one block
25% clamp per window: a one-shot pump moves the average under 1%.
Program
Terms
- 18+. Confirmed once, before your first ticket.
- A tote. 10% of every pool comes out (5% dev of the winning coin, 5% platform). Odds move until the off.
- Public data. Results come from the runners' PumpSwap pool prices, read on chain.
- Risks. Money can push a price; the clamp limits spikes, not a whole-race pump. pump.fun can change a coin's creator (read at the open). The program is upgradeable, no third-party audit yet. You can lose the whole stake.
- No promises. Not advice. The unicorns are coins, and coins go down.
