The pot and the burn

Every duel has a pot of ETH. When a round with a winner is settled, it can buy that side on its ETH pool, paying at most about 10% above that side's reference price, and burns every token it buys. A round without a winner carries the pot over.

Where the pot comes from

The table uses default launch terms; each duel’s fees and launch tax are fixed at its launch.

SourceShare
Swap fees34% of the 1.2% fee on every trade against ETH (67% for a supporter duel), plus what the protocol leaves of its share
Anti-snipe taxAll of it: the tax paid by buys in the first 10 seconds
RealignmentAll the profit of the hook's realignment after each trade

The pot is held by the hook as ETH claims in the Uniswap V4 PoolManager, apart from every other duel's pot. Nobody can withdraw it: it can only buy back its own duel's winner.

The buyback

When a round is settled with a winner, the pot buys that side with ETH on its ETH pool, then burns what it bought. The ETH spent goes into the pool, behind the tokens still in circulation.

The buyback has a price ceiling: it never pays more than about 10% above the winner's reference price. The reference is an exponential average of the ETH pool's ticks (log prices) with a 30-minute time constant — a price held for half an hour weighs about 63% of it, for an hour about 86% — except that it follows the price down at once: whenever the price is below its average, the price itself is the reference. The ceiling sits 953 ticks above it. The buyback spends the pot until it is gone, or until the price reaches the ceiling:

  • A pot that fits under the ceiling is spent in full.
  • A pot too big for its pool, such as the anti-snipe tax of a new duel, stops at the ceiling: the rest stays in the pot and buys at the next settlement, again up to 10% above the reference.
  • A price already at or past the ceiling when the round is settled buys nothing this time: the whole pot waits.

Try it: the buyback at settlement

The winner after, against its reference+6.1%

The whole pot buys tokens that are burned: the winner’s price rises +6.1%.

Simplified example with a fixed reference and each side valued 1.69 ETH at launch. The real ceiling is 10% above the winner’s reference: a 30-minute exponential average of its ETH-pool ticks, or its price when that is lower. A buyback never moves the price up by more than 10% from where it finds it, and by less when the price already rose above its average.

The reference rises gradually with prices held over time and falls at once with the price. If the current price is already at or above the ceiling, the buyback is skipped. The time-weighted ETH price lead determines the round's winner separately. Since the reference is never above the current price, a buyback never moves the price up by more than about 10% from where it finds it: tokens sold just before the close are not bought back near the average they left.

Unspent ETH stays in the pot for a later round. After a buyback, the hook attempts realignment; it may be limited or skipped, so the three prices need not agree exactly.

Why burn

When a buyback executes, burning makes the winning side scarcer: fewer tokens remain in circulation. A winning round that executes no buyback does not reduce supply through that buyback.

Watching it

On a duel's page, Pot shows the ETH waiting for the next buyback, and the Rounds tab lists every settled round: its winner, the ETH it spent and the tokens it burned. The leaderboard ranks duels by their burns.
