3mo SaturnOmnichainV4HookA minimal hook for the Saturn Omnichain project with only the `afterInitialize` permission active. The `afterInitialize` callback is a pure no-op stub; the contract also exposes `initializePools()` which calls an external `ISaturnOmnichainLiquidityBootstrapper` to bootstrap pool liquidity. Base afterInit 15 3mo SaturnOmnichainV4HookA hook with afterInitialize registered but implemented as a no-op. Provides a separate initializePools() function that calls an external ISaturnOmnichainLiquidityBootstrapper.bootstrap() to record the initial tick. All hook callbacks return their selectors unchanged without performing any logic. Base afterInit 15 3mo SaturnOmnichainV4HookA hook with only the afterInitialize permission, implemented as a no-op stub.

Base afterInit 15 3mo SaturnOmnichainV4HookA minimal hook for the Saturn Omnichain protocol that stores pool configuration constants and a reference to a liquidity bootstrapper contract. The afterInitialize callback is a no-op; pool initialization is triggered externally via initializePools(), which delegates to the bootstrapper. Base afterInit 15 3mo SaturnOmnichainV4HookA minimal hook for the Saturn Omnichain project that registers only the afterInitialize permission. The afterInitialize callback is a pure no-op stub; pool initialization and liquidity bootstrapping is coordinated externally via an ISaturnOmnichainLiquidityBootstrapper contract called through initializePools(). Base afterInit 15 3mo SaturnOmnichainV4HookA minimal hook that implements only afterInitialize, storing the initial pool tick via an external ISaturnOmnichainLiquidityBootstrapper.

Base beforeInitbeforeAddLiqbeforeSwapafterSwap+2 12 8mo MineSwapHookV2A universal fee-capture hook that deducts 0.15% of output tokens on every exact-input swap via afterSwapReturnsDelta, accumulating tokens in the contract. Anyone can trigger fee processing, which swaps accumulated tokens to BG via Uniswap V3, then splits the result: 50% burned to 0xdead, 49% sent to a rebate tracker for volume-based rewards, and 1% paid to the caller as a mining reward. Base afterSwapafterSwapDelta 12 13mo GlassHookStaticFeeV2A Uniswap v4 hook for Glass token launchpad pools that applies direction-dependent static LP fees (different rates for buying vs. selling the glass token), collects a ~20% protocol fee via BeforeSwapDelta/AfterSwapDelta, and includes an optional MEV-protection module that can temporarily raise fees for up to 2 minutes after pool creation. Base beforeInitbeforeAddLiqbeforeSwapafterSwap+2 12 17mo Limit Order Hook (Base)A limit order hook that records the tick before each swap and triggers limit order execution after the swap completes by delegating to a LimitOrderManager contract. It also supports role-based dynamic LP fee management via AccessControl. Base beforeSwapafterSwap 12 5mo IconCurveHookA bonding-curve AMM hook for player ("icon") tokens paired with country tokens. It intercepts every swap to price buys/sells using a virtual-reserves formula, mints/burns PlayerToken on demand, and burns a 5% fee on each trade. Trading is gated behind a phase2Active governance flag set by the owner or pack-opener. Base beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+2 11 11mo HaberdasheryHookA fee-taking hook that charges a 1% fee on each swap via beforeSwapReturnsDelta, capturing the input-side token as protocol revenue retained by the contract. The owner can withdraw accumulated fees, with non-Habs tokens automatically swapped to a designated Habs token through an internal pool swap. Base beforeSwapswapDelta 11 3mo SaturnOmnichainV4HookA minimal Uniswap v4 hook for the Saturn Omnichain protocol.
