It simulates each swap to estimate the post-swap tick, computes a volatility accumulator from tick displacement relative to a reference tick, and calls updateDynamicLPFee with a fee that scales quadratically with volatility, bounded by configurable base and max fee parameters. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 7 2mo PonsV2MemeHookA singleton Uniswap v4 hook for graduated Pons v2 memecoin pools. Takes a hook fee plus an optional creator tax on every swap via afterSwap return delta, accumulating fees in pending balances. A trusted sweep operator periodically converts memecoin-denominated fees to the pool's quote currency via internal swaps, then distributes proceeds among the protocol, a buyback-and-lock vault (five-year vest), and the pool creator.

Fees are accumulated as claimable balances for the token creator and distributed via a factory registry.

Charges 1–7% ETH fees on buys (in beforeSwap) and sells (in afterSwap), with the fee scaling linearly based on tick movement from the previous swap. Only exact-input swaps are permitted; only the bound factory may register pools.

Fees are collected as ERC-6909 claims and swept to an immutable feeWallet; all parameters (fee bounds, fee destination) are fixed at deployment. Exact-output swaps are refused. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 7 2mo LaunchHookA shared Uniswap v4 hook for B20 token launchpads that gates pool creation to a factory, permanently locks single-sided liquidity, and charges a configurable swap fee (split among creator, platform, and optional referrer) plus a timestamp-anchored anti-snipe surcharge that decays to the base fee over a configurable window. Base beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 7 2mo WethFeeHookImmutableAn immutable Uniswap v4 hook that charges a WETH-denominated fee on every swap using per-token tiers (3%, 5%, or 10%) from a launchpad registry, or a global fallback rate. Accrued fees are held as ERC-6909 claims and distributed via a permissionless distribute() call that splits proceeds between the token creator, treasury, a flagship buyback vault, and the token's on-chain mechanism. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 7 2mo StonkBrokerHookA Uniswap v4 hook for ETH/token pools that charges a configurable flat fee (up to 5%) in ETH on every swap. On buys (ETH in), the fee is deducted from the input via beforeSwap delta; on sells (ETH out), from the output via afterSwap delta. Fees are sent directly to a per-pool recipient address during the swap. Only exact-input swaps are permitted.

Applies anti-snipe surcharges on early buys and deployer-dump penalties on sells within a time window, with a portion of creator fees automatically used for buyback-and-burn via nested swaps.

Applies a decaying anti-snipe surcharge on buys in early blocks post-launch and a time-limited surcharge on sells from the original deployer address.

Sell-exact-out swaps are rejected; hookData optionally encodes a referrer address. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 7 3mo 0x2b6a…0800Gates who can add liquidity BNB beforeAddLiq 7 3mo AtomicLimitOrderHookAtomicLimitOrderHook atomically combines a swap and a limit-order placement in a single transaction, extending OpenZeppelin's LimitOrderHook. It prevents front-running between the two steps and adds guards that keep order accounting consistent under aggregator-style multi-hop swaps. Uses the AFTER_INITIALIZE and AFTER_SWAP flags; ordinary swaps through the pool require no custom hook data. Ethereum afterInitafterSwap 7 3mo LaunchpadHookCollects fees on every ETH/token swap, splits them between the token creator and platform treasury, distributes referral cuts from the platform share through a tiered referral chain, and records ETH volume per token for graduation tracking. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 7 3mo PRNTRHookCollects per-swap fees on ETH-in (zeroForOne) and ETH-out (oneForZero) legs using a configurable fee tier (100–500 bps). Applies an 85% anti-sniper fee during the first 30 seconds after pool launch. Accumulated WETH fees are claimable by a registered factory address; the factory itself is exempt from all fees. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 7 3mo 0xf3a6…c800Gates who can add liquidity BNB beforeAddLiq 7 3mo LaunchFeeHookCharges a configurable fee (up to 5%, set at deployment) on the ETH side of swaps in native-ETH launchpad pools. Fees are collected in beforeSwap (ETH-specified trades) and afterSwap (token-specified trades) via delta returns, then forwarded to a LaunchFeeSplitter contract that attributes them to each token's creator.
