EggsNodeHookA Uniswap v4 hook that automatically mints farm "hen nodes" to traders who buy EGGS tokens and burns their nodes proportionally when they sell, by calling an external node manager contract in afterSwap. The hook is owner-controlled via an on/off switch and a per-swap node cap.

ReefGuardFeeHookA Uniswap v4 hook for the $REEFGUARD token that applies a fixed 5% fee on all swaps (buys and sells), always collecting the fee in ETH (currency0) and forwarding it to an immutable feeRecipient address. Fees are skimmed via BeforeSwapDelta in beforeSwap when ETH is the specified currency, and via afterSwap return delta otherwise.

TrinityHookUniswap v4 hook for a TRI/ETH pool that charges a flat 3% fee on every swap (split 1% burn, 1% liquidity reinvestment, 1% rewards). In afterSwap it skims the fee from the unspecified currency via the afterSwapReturnsDelta mechanism and routes it into accounting buckets; heavy actions (burns, conversions, liquidity adds) execute separately in keeper-callable transactions.

PadFeeHookSingleton hook shared by all graduated pons v2 memecoin pools. Collects protocol, launchpad, creator, and charity fees from the quote leg, and optional burn fees from the memecoin leg, on every swap. Applies a time-decaying snipe tax on early buys. On buys, optionally stakes half of post-burn memecoin in a CoinFlip game. Supports per-pool rich/poor wallet balance gates and FOMO-only relayer allowlists.

TrinityHookCharges a flat fee (default 3%) on every swap through a TRI/ETH pool, skimming the unspecified currency in afterSwap via a return delta.

GlueHookA buyback-and-burn Uniswap v4 hook that absorbs main-token sells from an on-hook pot at the pool's own execution price (shield), and buys back the main token on detected buy swaps up to a sandwich-proof fee cap (pump). Optionally supports auto-compounding concentrated-liquidity LP fee programs with configurable split allocations.

GlueHookImplements a shield-and-pump mechanism for configured pools: beforeSwap intercepts sells of a designated main token by absorbing them from a pre-funded secondary-token pot (returning a BeforeSwapDelta), while afterSwap amplifies buys by spending pot reserves on a nested pump swap and auto-harvests LP fees on every swap.

RetardV111DelayedHookProxyA time-delayed upgradeable proxy for a Uniswap v4 hook using EIP-1967 storage slots and delegatecall. The proxied implementation handles beforeSwap (with delta return), beforeAddLiquidity, and beforeInitialize. Upgrades require a minimum 1-day delay, must be scheduled then executed by an authority address, and are validated for storage-version and config compatibility.

ModularLaunchpadHookModular Uniswap v4 launchpad hook with optional anti-snipe (time-based per-buy WETH cap curve), buy throttle (pool-wide rate limit during launch window), and JIT liquidity defense. Supports two fee models: standard (per-swap afterSwap take with optional creator-burn and liquidity-deepening redirects) or universal (hook-held seed LP with permissionless harvest() into a 70/30 creator/protocol split). This instance uses universal economics with anti-snipe enabled.
