2mo SparkHookA fee-collecting hook for Spark token launches that charges protocol and creator fees on swaps using quote-token amounts, with a block-number-based anti-snipe mechanism that applies elevated fees to early buyers within a configurable window after launch. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 12 2mo 0xa2d5…40c4Runs code on every swap · Can take tokens from swaps · Sets its own swap fee Base beforeSwapafterSwapafterSwapDelta 12 2mo StonkHookAfter-swap fee hook for StonkPad that charges platform fees (100–200 bps) plus dev-configured taxes (marketing, rewards, burn) on each swap's unspecified currency via afterSwapReturnsDelta, and tracks cumulative volume to unlock a 5% $STONK airdrop for instant-listed pools. Ethereum afterSwapafterSwapDelta 12 2mo FarmIndexFeeHookVolatility-based fee hook for FarmIndex pools that charges ETH fees on every swap. Buy fees are deducted from the ETH input in beforeSwap; sell fees are deducted from the ETH output in afterSwap. The fee rate scales between a pool-configured base and max (both within 1–5%) based on the previous swap's tick movement, and is forwarded directly to a per-pool fee recipient. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 12 3mo HookrHookShared Uniswap v4 hook for Hookr-graduated pools with configurable anti-snipe guard (block-gated buy caps and extra LP fees), dynamic surge fees scaled by trade size, auto-burn of token output to 0xdEaD, LP reward donations inside the swap, and a deterministic per-pool jackpot on qualifying buys (no randomness claimed). Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 12 3mo JetstreamHookSingleton hook that charges a configurable fee (up to 3%) on the ETH leg of every swap, distributing proceeds between the pool creator, a buyback wallet, and a platform wallet. Liquidity additions are gated until the pool is registered by the factory. Robinhood beforeAddLiqbeforeSwapafterSwapswapDelta+1 12 3mo BangHookFee-taking hook for ETH-paired pools that charges a creator rate (1–5%) plus an immutable 1% platform fee on every swap. Fees are accrued as ERC-6909 claims and can be permissionlessly swept to an immutable platform wallet or per-pool dividend vaults. Robinhood afterInitbeforeSwapafterSwapswapDelta+1 12 3mo ERC1967ProxyUpgradeable hook deployed as an ERC1967 proxy; the implementation contract source is unresolved. Based on address flags, it intercepts swaps and liquidity additions, returning swap deltas from both beforeSwap and afterSwap. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 12 3mo UniversalKlikHookMarket-cap-tiered fee hook for ETH-paired pools that charges fees on buys and sells, splitting proceeds between a platform treasury and the token creator address. Fees range from 1% (low market cap) to 0.1% (high market cap), applied via BeforeSwapDelta on exact-input buys and AfterSwapDelta on exact-output buys and exact-input sells. Exact-output sells are blocked. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 12 4mo HoodMarketsHookStaticFeeV2HoodMarkets protocol hook with static per-pool LP fees (capped at 10%) and a 20% protocol fee extracted on each swap via delta manipulation. Features a time-limited MEV module (active for 2 minutes post-deployment) that can temporarily raise fees, and optional pool extensions invoked in afterSwap. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 12 4mo Sa1tHookV2A bonding-curve launchpad hook serving every SA1T token pool through three phases: CURVE (custom constant-product AMM via ERC-6909 claims, fully NoOp'd against the pool), REFUND_WINDOW (optional money-back sells at average entry price), and AMM (full-range liquidity locked in LPLocker with TWAP oracle). Applies a 1.5% fee split between protocol and creator, plus an optional mechanic fee, on both buys and sells across all phases. Ethereum beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 12 4mo BracketHookBracketHook is the central contract for the TheCup protocol, managing 48 country-token pools across two AMM regimes: a bonding curve phase (hook handles all swap math via custom virtual-reserve AMM and a 1% protocol fee) and a graduated phase (standard v4 AMM with 1% protocol fee plus an optional 9% elimination tax on sells of knocked-out country tokens). A per-block price-impact cap (5%) is enforced as a sandwich protection mechanism.

Blocks swaps until the token has graduated from the launchpad's bonding curve. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 12 8mo ClankerHookStaticFeeV2Clanker v2 hook that applies asymmetric static LP fees per pool (separate rates for buying vs selling the Clanker token), collects a 20% protocol fee on all swaps by manipulating beforeSwap/afterSwap deltas, and optionally runs a MEV protection module active for 2 minutes post-launch plus pool extension callbacks. Base beforeInitbeforeAddLiqbeforeSwapafterSwap+2 12 8mo MineSwapHookV2A universal fee-capture hook that deducts 0.15% of output tokens on every exact-input swap via afterSwapReturnsDelta, accumulating tokens in the contract. Anyone can trigger fee processing, which swaps accumulated tokens to BG via Uniswap V3, then splits the result: 50% burned to 0xdead, 49% sent to a rebate tracker for volume-based rewards, and 1% paid to the caller as a mining reward.

Base beforeInitbeforeAddLiqbeforeSwapafterSwap+2 12 17mo Limit Order Hook (Base)A limit order hook that records the tick before each swap and triggers limit order execution after the swap completes by delegating to a LimitOrderManager contract.

Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 11 59d FiverHookA swap-fee levy hook that deducts a configurable percentage (levy rate, default 1%, max 5%) of each swap's quote-token amount from registered token pools, using beforeSwap and afterSwap return deltas to extract the toll and accrue it to the token issuer's claimable stash.
