No. Once you are King, you can sell your $KING whenever you want and you stay King until someone makes a bigger buy. The only limit: you cannot sell in the same transaction as the buy that crowned you (this blocks flash “buy-and-dump” crowns). From the next transaction on, selling is free.

If nobody takes the crown, there is no winner: the whole prize pool (ETH and KING) rolls over into the next round, which then starts with a bigger pot.

If you are the King when the timer ends, a Claim button appears on the game page. One click settles the round (if nobody did yet) and sends the prize to your wallet, in ETH and in $KING — 100% of the pot. Your winnings never expire.

Yes. The pool is a regular Uniswap v4 ETH/KING pool on Uniswap's standard fee tier, and the hook never changes swap amounts, so the Uniswap app and any router can trade it: thepool fee is taken on every swap and feeds the pot, and a buy made on Uniswap takes the crown exactly like one made here. The hook asks Uniswap's router who placed the trade (falling back to the wallet that sent the transaction). Only orders filled by a third party (intents, solvers) credit that filler instead of you.

Yes, if you are going for the crown. With UniswapX, your order is filled by a third party (a “filler”) who makes the swap for you: for the game, the buyer is the filler, so the filler would be crowned instead of you. In the Uniswap app, open the swap settings and turn UniswapX off before buying, so the swap goes through Uniswap's router from your own wallet. Buys made in this app never use UniswapX.

Yes. The whole $KING supply was seeded as liquidity at launch and the position belongs to the KingdomHook contract. The owner can withdraw it at any time, without notice, for example to migrate the game: the ETH and the unsold $KING in the pool go back to the owner as they are (nothing is swapped). It closes the game for good: the current round ends right away, its King gets the pot (with no King, it goes to the treasury), and all unclaimed winnings stay claimable. The owner can never touch the pot or the winnings, and your $KING stay yours. If ownership is renounced, the liquidity is locked forever. Nobody else can add liquidity to the pool.

The timer is fixed and is never extended. The last qualifying buy mined before the end wins: if a bigger buy lands in a block after the deadline, it no longer counts for that round.

The pool uses Uniswap's standard fee tier: every buy and sell pays it, on its input side — in ETH for a buy, in $KING for a sell. The KingdomHook is the pool's only liquidity provider, so it earns 100% of these fees and puts them all in the prize pool of the current round. The King wins both, ETH and $KING. No treasury cut.

No. The contracts have not been audited. Treat it as an experimental game: play responsibly and only with amounts you can afford to lose.

The game runs on Base. It is built for Uniswap v4, so it can be deployed on any chain where Uniswap v4 is live.
