Every coin
has an enemy.

Launch two rival coins at once. Every 15 minutes, the fees from both go to holders of the one with the higher market cap.

Drag the rope, or tap a side to give it a heave.

How a round works

A battle is a series of rounds with no end date. The loser never loses anything, and both coins keep trading. Read the full rules

1
Two coins launch together.
A creator names both sides and buys the same amount of each. Both go live on StonkFun in the same transaction. Neither can exist alone.
2
Trading feeds one shared pot.
Half a percent of every trade on either coin goes into the battle's pot. The creator takes nothing. It all goes to the winners.
3
The bell rings every 15 minutes.
The coin with the higher average market cap over the round wins it. Its holders are sent the pot, including the fees the loser generated.

Three rules keep the winner honest. Try the first one yourself: pump the teal coin just before the bell and see who wins.

Average, not last price: A round is won on time-weighted average market cap. A last-second spike barely moves it.
Hold through the bell: Your share is your smallest balance during the round. Buying mid-round counts from the next one.
Both sides cancel out: Holding both coins nets to your excess on the winner. Hedging earns nothing.

Teal is ahead when the bell rings, and Copper still wins the round.

No launch fee. You pay network rent and an equal dev buy on both sides, capped at five percent of each curve.
