5mo 0x397f…8145Runs code on every swap · Can take tokens from swaps · Sets its own swap fee · Takes a cut when LPs withdraw Base afterRemoveLiqafterSwapafterSwapDeltaremoveLiqDelta 2 6mo ButeA bonding-curve ERC-20 token (BUTE) that uses beforeSwap to intercept ETH-in swaps: it mints BUTE via a multi-factor curve (temporal decay, burn echo, peak bonus) and returns a BeforeSwapDelta, routing buys through the hook's own ETH reserve. Sell-side swaps pass through unmodified; selling BUTE is handled via a direct sell() function. Base beforeSwapswapDelta 2 6mo HomelanderUniV4PluginA Uniswap v4 hook that dynamically overrides the LP fee in beforeSwap (zero for a privileged MEV executor, configurable for all others) and runs on-chain arbitrage in afterSwap by delegating to an external MEV router and executor, distributing captured profits via a configurable profit distributor.

Pool initialization is gated to a factory address; exact-output swaps are unconditionally rejected. Base beforeInitbeforeSwapswapDelta 2 6mo BpegHookCalls `start` on a configured ERC token when the first liquidity is added to its pool, and updates an on-chain random seed (using block entropy) on each swap involving that token. Base afterAddLiqafterSwap 2 6mo BpegHookSyncs BPEG token holder NFT counts after swaps by calling syncSwap() on the BPEG contract in afterSwap, and sets the pool address on the BPEG contract in afterAddLiquidity when the first liquidity is added.

Users configure and deploy grid orders across price ranges; the hook tracks cumulative tick movement per block and reverts swaps that exceed a maximum price impact of 500 ticks per block to protect against excessive volatility.

Accumulated protocol fees are held as ERC-6909 claims and can be swept to a treasury address by calling `handleHookFees()`.

LP fees are donated as MAYBE to liquidity providers. Base beforeInitbeforeSwapafterSwapswapDelta+1 2 7mo LightspeedPoolHookTakes a fixed 0.3% fee from the canonical currency (e.g. SPEED) on every swap and forwards it to a FeeCollector address via afterSwap delta return. Tracks accumulated fees per epoch per pool for trustless ranking in launch pool competitions.

Fees are split 70/30 between the token beneficiary and the platform, with configurable multi-wallet fee distribution.
