3mo LaunchHookA shared multi-pool hook that applies a linearly decaying dynamic LP fee (from a configurable high start rate to a lower end rate over a set time window) to deter sniping at token launch. Each pool gets its own fee schedule keyed by pool ID, seeded at initialization and updated per-swap by the owner-configured schedule. Robinhood afterInitbeforeSwap 4 3mo NoxaHookA shared Uniswap v4 hook for meme coin fair-launches that charges a fixed 1% tax on the base asset (WETH) side of every buy and sell, minting the collected tax as ERC-6909 claims to the launched token contract. Pool creation is restricted to factory-registered pools only.

Fees are taken from ETH input on buys (beforeSwap delta) and from ETH output on sells (afterSwap delta), then routed to a per-pool recipient address registered by a factory.

During the curve phase, swap math is fully overridden and fees (protocol + referral + creator) are skimmed from the ETH side. At graduation, raised ETH and unsold tokens are seeded as locked full-range liquidity in the same pool. Post-graduation, the hook collects the same fee split from normal AMM swaps via beforeSwap/afterSwap return deltas.

During the bonding curve phase it NoOps the core AMM entirely, pricing trades against a virtual-reserve constant-product curve with a 1% fee; after the curve sells out, it graduates the pool to a standard AMM and continues charging a 1% fee on all swaps via delta returns. External liquidity addition and removal are permanently blocked. Ethereum beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 4 4mo V4TaxHookApplies a fixed 5% buy and 5% sell tax on swaps in registered pools. Tax is collected in the base asset via beforeSwap/afterSwap deltas, minted to the token address, and recorded as dividends through the token's recordTaxFromHook function. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 4 5mo FloorPad Floor HookSingleton Uniswap v4 hook serving all FloorPad memecoins (per-pool state keyed by poolId). On each buy, diverts a dynamic cut of the WETH input into a per-pool vault and fees to protocol/creator; on each sell, skims a fee from the WETH output. The vault backs a WETH-per-token redemption floor that ratchets up only on buys; holders can burn coins to redeem at the floor at any time.

Applies a flat 1% fee on every swap; on buys, fee tokens are swapped back to ETH and forwarded to a FeeSplitter. During the first 15 minutes after launch, if the pool has nftOnlyPeriod enabled, only holders of the original TenThousandTokens NFT collection may buy. Ethereum beforeInitafterAddLiqafterSwapafterSwapDelta 4 5mo ForgeHookA shared hook for Forge V4 pools that enforces factory-only pool initialization and applies a parabolic descending MEV protection fee, starting at 80% and decaying to 1.5% over a 30-second window after pool creation. Base beforeInitbeforeSwap 4 5mo UmiaHookSingleton Uniswap v4 hook for Umia LBP (Liquidity Bootstrapping Pool) pools. Enforces full-range-only liquidity positions, maintains a TWAP oracle (ring-buffer observations written before each swap and liquidity event), and deducts a configurable protocol fee from each swap's output side via afterSwapReturnsDelta, crediting it to a per-pool fee recipient.

Distributes SPUDS token rewards to full-range LP positions and single-asset stakers proportionally, and allows anyone to trigger periodic buyback-and-burn of SPUDS using accumulated swap fees from the hook-owned genesis liquidity position.

Ethereum beforeInitbeforeAddLiqafterSwap 4 6mo OneTimeLaunchHookTemplateA one-time launch hook that restricts each token's pool initialization and initial liquidity addition to a single occurrence.

When a user buys BPEG tokens, the hook mints NFT metadata proportional to their integer balance. When they sell, it burns NFT metadata accordingly. Uses tx.origin to identify the end user. Base afterSwap 4 6mo TokenpadHookApplies tiered ETH fees on all swaps (buys and sells) based on the token's current market cap, splitting fees among platform, creator, and stakers via a registered LaunchToken contract.

On buys, INU NFTs are minted to the buyer; on sells, NFTs are burned LIFO from the seller's inventory.

Fees step down from 1.25% to 0.35% as market cap increases (queried from an external factory); no fee is taken on the pool's deployment block.
