6mo UnipixelHookA Uniswap v4 afterSwap hook for the Unipixel collaborative pixel canvas. On $uPIXEL token sells, it reads the seller address from hookData and calls the canvas contract to reconcile the seller's pixel allocation to their new token balance. Reconciliation is best-effort via try/catch; swaps always proceed regardless of canvas state. Ethereum afterSwap 2 6mo 0x2fb1…8488Runs code on every swap · Can take tokens from swaps Ethereum afterAddLiqbeforeSwapswapDelta 2 6mo DynopegHookApplies a flat 3% ETH tax on every swap involving native ETH: on the buy side, reduces the swap input via BeforeSwapDelta and mints ERC-6909 claims; on the sell side, extracts ETH via poolManager.take() in afterSwap. Also advances a rolling per-swap entropy seed each call. Anyone can call normalize() to convert accumulated claims to physical ETH and push them to the DynopegToken reward distributor. Ethereum beforeSwapafterSwap 2 6mo Unilaunch Fee HookSingleton v4 hook for Unilaunch pools that skims a configurable per-pool fee (50–1000 bps) from each swap and splits it 60% to the pool creator and 40% to a fixed platform wallet. Only pools registered by the factory can initialize with this hook.

Ethereum afterInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 2 11mo DragonXHookA Uniswap v4 hook combining limit orders with a tax mechanism: market sells incur a 10% tax (split between genesis wallets and a buy-and-stake contract), while limit order sells incur a 0.5% tax.

Ethereum afterInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 2 11mo ImpactHookComputes a dynamic LP fee based on estimated price impact and an illiquidity metric (price impact divided by swap volume), overriding the fee before each swap via OVERRIDE_FEE_FLAG.

Ethereum beforeSwapafterSwapafterSwapDelta 2 13mo NFTEngineHookA Uniswap v4 hook for the NFTEngine platform that gates pool initialization and liquidity additions to factory-authorized callers. In afterSwap, it takes a graduated fee (starting at 95% for buys, decaying ~1% per 5 blocks to a 10% floor; flat 10% for sells), swaps token fees to ETH, and distributes 80% to the NFT collection engine and 20% to a configurable fee recipient.
