SaturnOmnichainV4HookA hook for the Saturn Omnichain protocol that records pool initialization state. Only the `afterInitialize` flag is active; the callback is a no-op returning only the selector. Pool setup is delegated to an external liquidity bootstrapper via `initializePools()`.

SaturnOmnichainV4HookA minimal hook for the Saturn Omnichain project that enables only afterInitialize (which performs no action beyond returning the selector).

SaturnOmnichainV4HookA Uniswap v4 hook for the Saturn Omnichain project. The only encoded permission is afterInitialize, which is a no-op returning the selector without executing logic. Pool bootstrapping is handled separately through an external initializePools() function that calls a LiquidityBootstrapper contract to set the initial liquidity and tick.

SaturnOmnichainV4HookA contract for the Saturn Omnichain project that enables initialization of Uniswap v4 pools; initializePools() calls an external liquidity bootstrapper and stores the resulting initial tick. The afterInitialize permission is enabled but the callback is a no-op. All other hook callbacks are also no-ops.

V4GasDetectHookA honeypot hook that unconditionally allows buy swaps (zeroForOne=true) but blocks real sell transactions by reverting when gasleft() is below 55M. Simulated sells (which use the full block gas limit) appear to succeed, deceiving users into buying tokens they cannot sell in real transactions.

InuPegHookA Uniswap v4 hook that imposes a trade tax on each swap — 2.5% on buys (2% to a rewards vault, 0.5% to a deployer address) and 2% on sells (ETH forwarded to the vault) — via afterSwapReturnsDelta. On buys it mints NFTs for the recipient per whole INU token unit received (capped at 3 per swap); on sells it burns NFTs LIFO from the seller's inventory.

Sa1tHookV2A bonding-curve launchpad hook serving every SA1T token pool through three phases: CURVE (custom constant-product AMM via ERC-6909 claims, fully NoOp'd against the pool), REFUND_WINDOW (optional money-back sells at average entry price), and AMM (full-range liquidity locked in LPLocker with TWAP oracle).

BracketHookBracketHook is the central contract for the TheCup protocol, managing 48 country-token pools across two AMM regimes: a bonding curve phase (hook handles all swap math via custom virtual-reserve AMM and a 1% protocol fee) and a graduated phase (standard v4 AMM with 1% protocol fee plus an optional 9% elimination tax on sells of knocked-out country tokens). A per-block price-impact cap (5%) is enforced as a sandwich protection mechanism.
