2mo MarketHoursFeeHookA Uniswap v4 hook that charges a dynamic LP fee based on US equity market session hours. It overrides the LP fee in beforeSwap with a base fee plus a time-varying surcharge (regular, extended, or closed session), routing all fees to LPs via the pool's native tick-crossing accounting. No owner, no admin, no settable state after deployment.

Liquidity addition is gated to the factory until graduation (price crosses a configurable tick threshold), after which the pool opens to external LPs.

Charges a fixed swap fee (0–5%, set per pool at launch) split between the creator, a protocol bid wall, and a platform treasury. Maintains a single-sided liquidity "bid wall" one tick-spacing below spot that captures sold tokens permanently, and gates liquidity additions to the factory until the pool graduates. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 2 2mo UnihoodStockHookA launch-platform hook for tokenized stocks that charges a fixed per-pool swap fee (0–5%, set at launch), splits it 80/5/15 between creator, bid-wall, and platform, and automatically places a single-sided quote-token liquidity range one tick spacing below spot using the wall share. Liquidity additions are restricted to the factory and the hook itself until the pool graduates past a configurable price threshold. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 2 2mo FablesRWAETHSession-aware dynamic-fee hook for tokenized equity (RWA) pools that sets LP fees based on US market calendar sessions (open, overnight, closed) with a linear opening descent and closing ramp driven by block.timestamp. Supports operator "poke" overrides with TTL and per-pool fee caps. The ETH variant adds native ETH (currency0) settlement support via WETH wrapping. Robinhood beforeInitbeforeSwap 2 2mo UnihoodStockHookA Uniswap v4 hook for tokenized stock launches that charges a per-pool fixed swap fee (0–5%, set at launch and immutable) split 80%/5%/15% among creator, bid-wall reserve, and platform. The bid wall places single-sided quote-token liquidity one tick spacing below spot; any tokens the wall acquires are permanently sequestered. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 2 2mo UnihoodStockHookA Uniswap v4 hook for token launches denominated in a tokenized stock quote currency. Charges a per-pool fixed swap fee (0–5%, set at launch, split 80/5/15 to creator/bid-wall/platform), manages a single-sided bid wall liquidity position below spot price funded by the wall fee share, and locks liquidity to only the factory and hook until the pool price reaches a graduation tick. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 2 2mo UnihoodStockHookA Uniswap v4 hook implementing a tokenized-stock launch mechanism where each pool has a fixed per-launch swap fee (0–5%), split among the creator, platform, and a bid-wall bucket. The bid wall periodically places single-sided quote-token liquidity one tick spacing below spot; captured tokens are permanently sequestered. A graduation threshold latches once price falls to a configured tick, after which external liquidity is unlocked.
