Walras is a Uniswap v4 hook that replaces continuous swapping with sealed batch auctions, orders collect for 60 seconds, opposing orders net against each other and the whole group settles at one uniform clearing price solved on-chain. Direct swaps against the pool revert, so there is no ordering advantage to win. • Walras @Debielily Hook page: atriumacademy.notion.site/Wa…

Assay is a Uniswap v4 hook that prices adverse selection per swap instead of per block. It measures the signed gap between the pool's tick and a Chainlink reference, and charges each order a share of the mispricing it actually captures, so an arbitrageur closing the gap and a retail swap widening it pay different rates in the same block. • Assay @RattiPrazwal Hook page: atriumacademy.notion.site/As…

Wick is a Uniswap v4 hook that settles swaps like a seventeenth century candle auction: orders gather while the candle burns, a random close block is drawn after the fact by Chainlink VRF, and everything clears at one uniform price. No deadline to snipe means no sandwich, and impatient flow pays a volatility priced premium that goes entirely to LPs. • Wick @Big14teru Hook page: atriumacademy.notion.site/Wi…

A Uniswap v4 hook that charges every swap a refundable deposit, then sixty seconds later uses the pool's own price to decide whether to give it back. Trades that leave the pool still mispriced forfeit the deposit to liquidity providers, and everyone else gets theirs back. • Impact Rebated Fees @raymondintell atriumacademy.notion.site/Im…

Hindsight is a Uniswap v4 hook that decides the fee after your trade: every swap posts a refundable 25 bps bond, and fifteen seconds later — measured on Unichain's 200ms flashblocks — the pool checks what the price actually did and either refunds it in full or forfeits it to the liquidity providers who wore the harm. Re-priced on 55,822 real Unichain mainnet swaps, benign flow pays the 5.00 bps headline, informed flow pays 12.32, and LPs recover 53.8% of the adverse selection they actually suffered. • Hindsight @_OoJae atriumacademy.notion.site/Hi…

Markout is a Uniswap v4 hook on the canonical Sepolia PoolManager that gives a pool 24 seconds of its own price memory and uses it twice: a spot lane that fills at 3 bps and escrows a live-quoted reversion-insurance premium, and an opt-in batch lane that nets opposing orders at the epoch TWAP without touching the curve. If the price comes back, the trader is paid in the settle transaction; if it holds, in-range LPs are credited in that same transaction. • Markout @0xshreyaas atriumacademy.notion.site/Ma…
