Fees are taken as BeforeSwapDelta/AfterSwapDelta adjustments and routed to a claimable balance for the token creator. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 6 2mo TokenLaunchpadA permissionless fixed-supply token launchpad hook for Uniswap v4. The beforeInitialize callback always reverts for external callers, ensuring only the launchpad itself can initialize launch pools via its createToken function, which atomically deploys a token, sets up a pool, and seeds permanent liquidity positions.

Ethereum beforeAddLiqbeforeSwap 6 2mo 0xd538…8044Runs code on every swap · Can take tokens from swaps Robinhood afterSwapafterSwapDelta 6 2mo SockMarketHookTriggers liquidity collection from a registered locker contract after each non-zeroForOne swap. Pools must be registered by a factory-authorized locker before swaps can proceed; unregistered pools revert. Protocol-initiated swaps (identified by hookData marker from the locker) skip collection to avoid recursion. Ethereum afterSwap 6 2mo 0x877d…00ccRuns code on every swap · Can take tokens from swaps Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 6 2mo NasdankFeeHookA Uniswap v4 hook that charges a fixed WETH-only fee on every swap through registered pools using return-delta accounting (beforeSwapReturnsDelta/afterSwapReturnsDelta). Accrued WETH fees are split between an immutable project treasury and protocol treasury at configurable proportions, claimable permissionlessly. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 6 2mo HookedV1A Uniswap v4 hook for MainToken/USDG trading pairs that collects fees via afterSwapReturnsDelta: 10% on buys (6.5% to a rewards collector, 2% to a jackpot, 1.5% to an ops wallet) and 3.5% on sells (2% to jackpot, 1.5% to ops). Liquidity provision is restricted to the owner and a configurable position manager. Robinhood beforeInitafterAddLiqafterRemoveLiqafterSwap+1 6 2mo LiquidityGuardHookRestricts liquidity additions to a single authorized hub address by reverting in beforeAddLiquidity if the sender is not the hub. All other hook callbacks revert unconditionally. Swaps are unrestricted and behave identically to a standard Uniswap v4 pool.

After 30 days, it may further reduce the fee based on fresh data from a SustainedFeeOracle. Only pools launched via the designated launch authority can use this hook. Unichain afterInitbeforeSwap 6 3mo MultiHookHostLaunchpad hook combining an optional anti-sniper temporal gate on early swaps, platform-and-creator fee redirection from swap output, and optional per-pool buyback-burn on token purchases. Pool initialization is restricted to an authorized Graduator contract set once by the deployer. Robinhood beforeInitbeforeSwapafterSwapafterSwapDelta 6 3mo 0x567b…e080Runs code on every swap · Runs at pool creation Robinhood beforeInitbeforeSwap 6 3mo DamperHookA sell-protection hook for newly launched token pools that applies dynamic surge fees and burns a portion of coins sold during a 3-hour post-launch damper window, scaling fees based on recent sell pressure and cumulative price impact. Liquidity mutations and pool initialization are restricted to the authorized launcher. Robinhood beforeInitafterInitbeforeAddLiqbeforeRemoveLiq+3 6 3mo RobinhoodMultiPairV4LaunchHookA multi-pair Uniswap v4 launch hook for the Robinhood Chain that atomically initializes and permanently funds up to four trading pairs (RWI, ETH, USDG, PONS) in a single transaction. Uses beforeSwap to match accumulated token-fee inventory against organic buys at the live pool price via a return delta, without moving the pool. Robinhood beforeInitbeforeSwapswapDelta 6 3mo 0x88a9…a8e4Runs code on every swap · Can take tokens from swaps · Gates who can add liquidity · Runs at pool creation · Handles donations to LPs Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 6 3mo DynamicFeeHookV1A Uniswap v4 hook that applies a time-and-FDV-based dynamic fee schedule to newly launched token pools: fees start at 1% for the first 7 days, then step down based on pool age and token fully-diluted value (via an external oracle), reaching a minimum of 0.1% at ≥$100M FDV. Also maintains an onchain TWAP with up to 128 observations to support at-least-24h price history queries. Unichain afterInitbeforeSwapafterSwap 6 3mo 0x3bff…5ac8Runs code on every swap · Can take tokens from swaps · Can block LP withdrawals · Gates who can add liquidity · Runs at pool creation Robinhood afterInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+2 6 3mo RobinhoodRWIV4LaunchHookFactory and hook for launching fixed-supply TOKEN/RWI pools on Robinhood Chain. Restricts pool initialization to the hook itself via beforeInitialize, and uses beforeSwap with a return delta to internally match accumulated token-fee inventory against organic RWI buys at the current pool price, routing that portion directly without going through the AMM curve. Robinhood beforeInitbeforeSwapswapDelta 6 3mo 0xee3d…40ccRuns code on every swap · Can take tokens from swaps Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 6 3mo ReflectionHookA shared Uniswap v4 hook for launchpad token pools that skims a per-pool ETH reflection fee plus a platform fee on every swap. Fees are collected as ERC-6909 ETH claims in beforeSwap (exact-in buys, exact-out sells) and afterSwap (exact-in sells, exact-out buys), then swept by a distributor. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 6 3mo 0x6d26…c044Runs code on every swap · Can take tokens from swaps Robinhood afterSwapafterSwapDelta 6 3mo 0xcda3…40ccRuns code on every swap · Can take tokens from swaps Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 6 3mo BurnOnSwapHookBurns a configurable percentage (up to 3%) of specified swap token amounts per pool by taking tokens from the pool manager and calling burn() on them. The burn token and fee rate are configured per pool by the owner. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 6 3mo 0x83c8…c080Runs code on every swap · Sets its own swap fee Robinhood beforeSwap 6 3mo PmavHookQuotedBonding curve launchpad hook (pmav.fun V2 quoted variant) that runs a constant-product curve phase with block+1 anti-snipe protection, decaying anti-snipe fee premium, per-wallet 2% buy cap with automatic refund waterfall, and 1% quote-denominated fee (70/30 creator/platform split). Automatically graduates to a standard full-range Uniswap V4 pool with dynamic LP fee when the curve raise target is reached. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 6 3mo ForgeHookV4A Forge platform hook that enforces configurable buy/sell fees (split among platform, creator, rewards, and utility recipients) taken via beforeSwap/afterSwap return deltas. Pools must be registered by a launchManager before trading, liquidity removal is permanently locked, and donations are disabled. Robinhood beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+4 6 3mo LaunchpadHookUniswap v4 hook for token launch pools. Takes WETH trading fees via beforeSwap/afterSwap deltas using either a time-decaying anti-snipe schedule or a market-cap-based fee curve. Splits fees between protocol, creator, and partner; routes the creator share through a keeper-permissionless flywheel for buyback-and-burn, auto-LP, token reflections, or WETH dividends. Blocks trading until a configured timestamp and lifts launch-window token transfer limits once price crosses a target market cap. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 6 3mo Flaunch PositionManagerFlaunch's full-lifecycle memecoin hook that manages token creation, fair launch periods, and ongoing trading. Implements an internal swap pool to fill orders from accumulated fees before hitting the Uniswap pool, fee distribution with optional referrer support, a bid wall mechanism, and temporal access control that gates swaps until a scheduled launch timestamp. Robinhood beforeInitbeforeAddLiqafterAddLiqbeforeRemoveLiq+6 6 3mo HoodXLaunchHookAn identity hook that gates pool initialization to a single bound factory address; pools created outside the HoodX factory are rejected. Swap and liquidity behavior are unmodified standard Uniswap v4. Robinhood beforeInit 6 3mo 0x3d64…0080Runs code on every swap Robinhood beforeSwap 6 3mo ReflectionFeeHookA 2% swap tax hook for graduated reflection-token pools. On ETH-specified swaps it takes a fixed 200 bps fee via beforeSwap/afterSwap return-delta callbacks and forwards it to a per-token fee bucket in the factory contract. Pool initialization is gated to a designated graduator address to prevent front-running. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 6 3mo ForgeHookV4A Uniswap v4 hook for token launches managed by a launchManager, enforcing configurable buy/sell fees distributed to platform, creator, rewards, and utility recipients via beforeSwap and afterSwap deltas.
