17mo TokenFabA token launch hook implementing a bonding curve for initial price discovery. When the bonding curve supply cap (15.75M tokens) is reached, it automatically removes liquidity and graduates to an AMM pool. Collects a 1% swap fee split 50/50 between creator and platform fee recipients. External liquidity management is blocked. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 6 18mo BackGeoOracleA TWAP oracle hook that records price observations and mitigates price impact by executing automatic backruns on large swaps, crediting the original sender with ERC6909 tokens. Only exact-input swaps are supported; calling routers must implement IMsgSender. Arbitrum beforeInitafterInitbeforeAddLiqbeforeRemoveLiq+3 6 18mo TokenFabToken launch factory hook implementing a bonding curve for newly deployed ERC-20 tokens. Blocks external pool initialization and liquidity additions, collects a 1% swap fee on the base token split between creator and platform, and automatically graduates tokens to a full-range AMM pool when the bonding curve supply threshold is reached. Base beforeInitbeforeAddLiqafterSwapafterSwapDelta 6 57d StonkHookV3A Uniswap v4 hook that gates swaps on a pluggable market-hours oracle (NYSE schedule), withholds an asset-leg fee on every swap split between permanent pool liquidity and project beneficiaries, and applies an exponentially decaying anti-snipe surcharge. Liquidity can only increase: `beforeRemoveLiquidity` unconditionally reverts any negative delta from any caller. Robinhood afterInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 5 57d BluestonkHookSkims a flat 2% fee on every swap denominated in the quote asset (currency1), split 50/50 between a platform wallet and the registered token creator. LP fee is forced to zero so all fees flow through the hook via beforeSwap and afterSwap delta returns. Base afterInitbeforeSwapafterSwapswapDelta+1 5 58d LaunchHookA token launch hook that seeds single-sided liquidity for new token pools, applies dynamic swap fees driven by each token's on-chain tax rate, collects and converts LP fees, routing proceeds to the token's fee distribution function. Also supports token buybacks triggered by the registered launch token contract. Robinhood beforeSwap 5 58d FugaziV4HookA Uniswap v4 hook for Fugazi token pools that collects a fixed 1% swap fee denominated in the reserve token and distributes it among a burn address, the token creator, and a protocol treasury. Only works with pools pairing a FugaziToken against a designated reserve token with zero LP fee. Ethereum beforeInitbeforeSwapafterSwapswapDelta+1 5 59d HookrModularHookV6WthV5Modular Uniswap v4 hook implementing Hookr's always-on WTH arbitrage-recapture profile. Runs MEV correction logic on every swap (before and after) via a pluggable module stack and a pinned accounting kernel, computing per-swap LP fees dynamically from base rate plus module surcharges. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 5 59d LemonV4TaxHookCollects a configurable trading tax (3–10% total) on every swap in the pool's paired asset, splitting it between a per-pool creator recipient and a fixed protocol recipient. Tax rates and recipients are set once by a designated launcher before pool initialization and are permanently immutable thereafter. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 5 2mo AnyQuoteSharedHookV1A shared Uniswap v4 hook for token launch pools that intercepts swaps to collect platform and creator fees, minting them as ERC-6909 claims to a ledger contract. Pool registration is restricted to an authorized host address; once registered, any user may swap freely.

Robinhood beforeInitafterSwapafterSwapDelta 5 2mo K401MarketHookInitialization gate for protocol-owned 401K/Stock pools. Restricts pool creation to a single authorized MarketReserve contract, enforcing fixed 0.30% fee, tick spacing of 60, and requiring the paired stock token to be actively approved in the StockPriceGuard oracle registry. Robinhood beforeInit 5 2mo UnihoodStockHookA Uniswap v4 hook for tokenized stock pools that charges a per-pool fixed swap fee (0–5%, set at launch) split among the creator, a bid wall, and a platform treasury. It automatically manages a single-sided liquidity range (bid wall) below current price using accumulated fee revenue, and restricts liquidity additions to the factory until the pool graduates. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 5 2mo BagrHookV4EA bonding curve launchpad hook that deploys tokens as single-sided concentrated Uniswap v4 positions. Restricts liquidity from overlapping the curve range. After each swap, observes whether the pool price has crossed the graduation tick and emits a Graduated event. Uses a flat static LP fee with no dynamic fee ramp or anti-sniper window. Robinhood beforeInitbeforeAddLiqafterSwap 5 2mo LeshyClassicQuoteFeeHookA Uniswap v4 hook for Leshy classic token pools that collects a controller-governed treasury fee on swaps, denominated in the quote asset. Fees are accrued as ERC-6909 claims via beforeSwap/afterSwap deltas and redeemable to the current treasury address. Pool initialization is gated to the registered factory adapter. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 5 2mo CBLaunchV4HookRestricts liquidity provision to a single immutable launcher address, ensuring a launch pool remains closed to outside liquidity providers. Swap behavior is completely unaffected — only `beforeAddLiquidity` is active, reverting any deposit from an address other than the launcher. Robinhood beforeAddLiq 5 2mo SpotA Uniswap v4 hook implementing dynamic swap fees based on oracle-tracked volatility and surge pricing, full-range liquidity management with fee reinvestment, and a truncated geometric price oracle. In addition to the declared protocol fee, charges a hardcoded undisclosed 0.10% "AGGRESSIVE_SURGE" fee on every swap (labeled "Скрытая комиссия" — hidden commission — in source comments), with both fees minted to the liquidity manager. Robinhood afterInitbeforeSwapafterSwapswapDelta+1 5 2mo EthicsV4FeeModeV2Uniswap v4 hook that collects a fixed 1% fee on swaps in the pool's quote currency, distributing it based on a configured mode: Creator mode splits between creator (70%) and an Ethics address (30%), Rewards mode splits between a rewards vault (90%) and Ethics (10%), and Burn mode burns the base token instead. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 5 2mo StrategyFeeHookCharges fixed 5% (500 bps) buy and sell fees on ETH-paired pools via swap delta manipulation. Fees are accumulated per pool and swept to a registered vault address by calling sweep(). Pools must be registered by a factory address before swaps are permitted.

Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 5 2mo PairV4HookA gating hook that restricts pool initialization to a designated launchpad address. Pools must be pre-authorized by the launchpad with specific project/quote token pairs, fee (1%), and tick spacing before they can be initialized. Robinhood beforeInit 5 2mo DynamicFeeHookV2Implements a dynamic LP fee that linearly decays from a high launch fee to a flat end fee over a configurable duration (anti-sniper mechanism), then holds the end fee permanently. Maintains a TWAP price oracle via per-swap sqrt-price accumulator updates. No pause or access control of any kind can halt swaps. Base beforeSwapafterSwap 5 2mo SpectraBlocklistHookUniswap v4 hook that blocks swaps from addresses on a configurable blocklist, checking both the immediate swap caller (sender) and tx.origin. The immutable owner can update the blocklist but cannot affect fees, liquidity, or swap amounts. Ethereum beforeSwap 5 2mo WraithVeilIntercepts swaps and fills up to 50% of each from an associated lending reserve (Crypt) at the pool's spot price plus a spread. Maintains a TWAP oracle and disables fills when spot price deviates more than 5% from the 15-minute average. Robinhood afterInitbeforeSwapafterSwapswapDelta 5 2mo BallisticFeeHookV3Charges time-decaying swap fees on the quote currency, splitting them between a pool creator and a platform treasury.

Base beforeInitbeforeSwapafterSwapswapDelta+1 5 2mo TripoolsAntiSnipeHookA shared Uniswap v4 hook for Tripools token-launch pools that enforces a 6-second anti-snipe window (50% flat tax on non-whitelisted buys) and a dynamic tiered fee schedule on all swaps. Ordinary buy/sell taxes split 20% to a protocol treasury and 80% accrued for the token creator in ETH; snipe taxes route 100% to the treasury. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 5 2mo WarzyHookSingleton launchpad hook for the Warzy platform on Robinhood Chain. Takes a 1% ETH fee on every swap (80% to the token's dev, 20% to treasury or parent-token holders via FeeDistributor). Enforces an anti-snipe warmup window after launch, locks liquidity so only the factory can add and nobody can remove, and automatically graduates tokens when their ETH FDV crosses a configurable threshold (USD-pegged via an on-chain oracle pool). Robinhood beforeAddLiqbeforeRemoveLiqbeforeSwapafterSwap+2 5 2mo AlphaHook2PctDynamic-fee hook for BSC token/stablecoin pairs that sets the LP fee between 0.30% and 2.00% based on volatility and volume EMAs, seeding the maximum fee at pool launch.

Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 5 3mo LaunchpadHookCollects a percentage fee on every swap in registered launchpad token pools, splitting proceeds between the token creator and a platform treasury with an optional referral chain deducted from the platform share. Tracks net quote volume per swap for token graduation accounting. BSC beforeSwapafterSwapswapDeltaafterSwapDelta 5 3mo PmavHookQuotedSlimXBonding curve launch hook that gates pool creation to an internal factory, enforces a block+1 anti-snipe delay, a permanent 2% wallet cap with automatic surplus refund, and a decaying anti-snipe fee premium on buys. Upon reaching the graduation raise target, the hook executes an inner swap, locks full-range liquidity, and updates the dynamic LP fee to a flat 1%. BSC beforeInitbeforeAddLiqbeforeSwapafterSwap+2 5 3mo EquifoldRaidHookA cosmetic observation hook for Equifold v4 launch pools that gamifies swap activity as a cooperative boss raid. Buys damage the boss and sells heal it based on quote volume; raid state resets every 10 minutes. No swap gating, no hookData required, and no effect on trade execution. Robinhood afterSwap 5 3mo VerdantHookFee schedule hook for Verdant markets that overrides LP fees in beforeSwap based on a pre-configured, time-based stage schedule stored per pool. Pool initialization and liquidity addition are restricted to the Verdant factory, making pools immutable after creation. No upgrade path, no delegatecall, no custody of assets. Robinhood beforeInitafterInitbeforeAddLiqbeforeSwap 5 3mo GammaHookImplements a time-decaying dynamic LP fee for pool launches: charges a high anti-snipe fee (peakFee) at launch that decays linearly to a steady-state base fee over a configurable shield window, then holds at baseFee. Fee configuration per pool is registered by a factory contract. Robinhood beforeSwap 5 3mo DegenSpyV3HookA Uniswap v4 hook for SPY/token pools that collects custom swap fees via BeforeSwapDelta and AfterSwapReturnsDelta, splitting proceeds between an operating treasury, a buyback vault, and per-pool beneficiaries.
