Round — · live on Ethereum · the throne is open

Were you in the last five?

KingV4 is a last-buyer experiment on Ethereum. The game contract is a Uniswap v4 hook — no keys, no dividends. You buy $KING on the hooked pool. Each ETH→token swap skims 2% of the ETH into the pot, puts your wallet on the board, and stalls the clock. When the clock hits zero, the last 5 unique wallets split 80% of the pot. Last buyer takes the biggest cut.

No promises. The pot is only what traders put in. Unaudited. Play with what you can afford to lose.

Last 5 unique wallets that bought this round. Position 1 is the current king — last buy on the clock.

    Buy $KING & stall the clock

    Swap ETH for the hooked token via Uniswap Universal Router. A buy ≥ 0.001 ETH crowns you, skims 2% into the pot (90% pot / 10% house), and adds 30 seconds — 2 minutes on the first buy, never more than 30 minutes from now.

    How it works

    Same last-buyer loop as FOMO 3D, stripped to a Uniswap v4 pool. Fuel is the swap, not a key.

    01 / BUY

    Swap feeds the pot

    Every ETH→token buy on the hooked pool skims a 2% ETH fee into the live round. 90% of that fee sits in the pot; 10% is house. Sells pay nothing and do not move the clock.

    02 / STALL

    The clock ticks down

    The round opens with 2 minutes. Each qualifying buy (≥ 0.001 ETH) adds 30 seconds, never more than 30 minutes from now. Size does not buy extra time — only a seat on the board.

    03 / WIN

    Last 5 split 80%

    When the clock hits zero, the last 5 unique wallets split the prize 50 / 20 / 15 / 10 / 5. 15% seeds the next round. 5% to the house. Dust (if fewer than 5) goes to the king.

    Lore

    KingV4 is the throne that keeps getting stolen. There is no court, no army — only a clock and a pot of ETH. Whoever buys last wears the crown. Whoever is still wearing it when the timer dies, eats.

    The experiment is public. The hook sits on the pool. Every buy is a vote that the round should live a little longer, and a bet that nobody else will snatch the seat before it ends.

    • Who counts as buyer. Uniswap v4 hooks see the router, not you. KingV4 records tx.origin — the wallet that signed. Buy from your own wallet.
    • Unique wallets. The board is the last 5 distinct addresses. Buying twice moves you to #1; it does not give you two seats.
    • Settlement. The next buy after expiry pays the last round and opens a new one. If trading goes quiet, anyone can call settle.
