Supports three fee modes: Creator (direct payout), Cashback (buyback-and-burn), and Holder Rewards. Enforces a configurable time-based maximum buy size during a pool's opening guard window. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 8 54d DynamicFeeRebalanceHookAdjusts LP fees dynamically based on an EMA of tick movement (bounded by configurable min/max and max step per block), skims a configurable revenue share from each swap into ERC-6909 claims redeemable by the fee recipient, and emits non-custodial upward-rebalance suggestions when the pool price drifts above a configured tick threshold.

Only owner-approved pools containing the IMX5 token are permitted to swap.

It acts as the sole liquidity provider, applies dynamic LP fees per swap direction, collects protocol fees with optional referral attribution, and uses delegatecall to a fixed fee-facet for fee distribution. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 8 2mo UnihoodStockHookA token launch platform hook denominated in a tokenized ERC-20 stock. Charges a fixed swap fee (0–5%, configured per pool at launch) split between creator, bid wall, and platform. Automatically manages a single-sided quote-token bid wall just below spot price. Liquidity additions are locked to the factory until the pool reaches a configured graduation tick, after which the pool opens to all liquidity providers. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 8 2mo PoolGuardA per-pool afterSwap hook that enforces sell limits during a time-boxed launch window. During the window, swaps that sell the designated token above a threshold (measured in paired-currency units) are reverted, unless the sender is on the owner-managed exempt list. After the window expires, no enforcement occurs. Robinhood afterSwap 8 2mo TweetPadV8InitializationHookA beforeInitialize-only hook that gates pool creation to a trusted adapter contract verified by runtime bytecode hash and portal address. Enforces that only WETH pairs with a fixed 0.3% fee and tick spacing of 60 can be initialized through the hook. Robinhood beforeInit 8 2mo StonkHookA Uniswap v4 hook for Stonk protocol pools that gates swaps to NYSE trading hours, permanently locks protocol liquidity, enforces a per-swap size cap, and withholds a flat fee from the asset leg via delta returns instead of the native LP fee.

On each swap, it deducts a configurable fee (default 1%, max 3%) from the quote-token leg and credits it to the token's creator. Buys within a configurable block window after launch incur a higher anti-snipe tax (default 12%). Fees accumulate in the hook and are claimable by token creators. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 8 2mo V4FunFeeHookVolatility-based fee hook for ETH/token pools on the v4.fun launcher. Charges fees in native ETH on buys (via beforeSwap delta) and sells (via afterSwap delta), scaling between configurable base and max rates (1%–7%) based on the previous swap's tick movement. Exact-output swaps are blocked.

Fees accumulate as ERC-6909 claims inside the pool manager and can be permissionlessly swept to the pad's fee wallet.

Operates only on factory-registered ETH/token pools. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 8 2mo 0xc582…40ccRuns code on every swap · Can take tokens from swaps Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 8 2mo FlareHookUniswap v4 hook for the Flare launchpad that charges a flat 1% fee on every swap in pools containing factory-listed tokens. Fees are accumulated in the hook contract and withdrawn to a configurable vault address. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 8 2mo DoubleBackedMultiTokenFeeHookCharges a fixed 3% fee on swaps in pools containing the BACKEDD token, taking the fee in the non-BACKEDD token and sending it to a immutable vault address. The fee is split between beforeSwap and afterSwap depending on whether the non-BACKEDD token is the specified or unspecified swap amount. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 8 2mo TaxHookA Uniswap v4 hook that applies fixed buy (3%) and sell (6%) taxes on swaps involving a designated token, deducted from the unspecified currency in afterSwap as ERC-6909 claims. Fees accumulate to the hook contract and are swept permissionlessly to a treasury address governed by a 3-day owner-controlled timelock.

Tax rates are compile-time constants; fees are forwarded to a treasury address controlled by an owner with a 3-day timelock. Robinhood afterSwapafterSwapDelta 8 2mo LaunchHookToken launch hook that manages a Registered → Launching → Live lifecycle, restricting swaps to the factory during launch and applying a time-based anti-snipe fee (higher fee for SNIPE_DURATION seconds post-launch). Fees are extracted via beforeSwap/afterSwap return deltas in native ETH and routed to a per-pool FeeVault for the creator. Maintains an on-chain TWAP oracle updated on every swap. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 8 2mo AirlockGateLaunch-window gate that records whether each swap originates from a whitelisted router (via transient storage, read by AirlockToken) and collects a capped platform fee (≤1%) on exactInput swaps during a configurable time window set by an authorized launchpad. Robinhood beforeSwapswapDelta 8 2mo UnifleHookA pure afterSwap observer hook for Unifle-launched token pools on Robinhood chain. Emits a SwapObserved event on every swap for off-chain analytics indexing; does not modify swap deltas or collect fees (fees are handled by the ERC-20 token's _update() override). Robinhood afterSwap 8 3mo PeepsV4TaxHookA tax-on-swap hook for Peeps V4 token launches that skims configurable buy/sell taxes via BeforeSwapDelta, then distributes collected amounts across funds, burn, dividend, and liquidity sinks in afterSwap. Enforces an optional anti-farmer window blocking third-party LP additions, and gates all swaps via a registry-controlled clearing window.

Charges ETH fees on buys via dynamic LP fee override and on exact-input sells by taking ETH output via afterSwap delta, accumulating sell fees in the hook for off-path collection by a privileged locker. Robinhood beforeSwapafterSwapafterSwapDelta 8 3mo FeraHookUniswap v4 hook implementing regime-specific dynamic LP fees — MEME pools use an EWMA volatility/flow estimator, RWA pools use a Chainlink oracle price-deviation overlay — plus a cumulative-tick TWAP oracle and an economic anti-JIT guard that withholds and linearly decays accrued fees on fast liquidity removal. Robinhood beforeInitafterAddLiqafterRemoveLiqbeforeSwap+3 8 3mo VladdyHookA fee-taking hook for native ETH/TOKEN pools that intercepts swaps to collect ETH-denominated fees, instantly distributing them to configurable recipients, a platform wallet, and a buyback reserve. Supports multiple distribution modes: direct recipient payouts, token buyback-and-burn, staking rewards (robin mode), lottery draws, and protocol-owned liquidity minting. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 8 3mo PRNTRHookA Uniswap v4 hook that implements tiered fee collection: charges an 85% anti-sniper fee for the first 30 seconds after pool launch, then applies a configurable base fee (100–500 bps). Fees are taken via poolManager.take() in both beforeSwap and afterSwap, accumulated per pool, and claimable by the factory in ETH.

Applies a market-cap-scaled dynamic LP fee (1.25% below $25k FDV, 1.00% above) pre-graduation, switching to a 0.30% LP fee post-graduation. Fees are split between the pool creator and the protocol treasury via a pull-pattern claim.
