If the deviation exceeds a configurable basis-point threshold, emits an ArbDetected event for off-chain arbitrage bots. No on-chain trade execution occurs. Arbitrum afterSwap 1 8mo AlphixJIT (just-in-time) liquidity hook that atomically adds concentrated liquidity around each swap in beforeSwap and removes it in afterSwap to improve price execution. Uses a dynamic fee algorithm that adjusts LP fees based on the pool's token ratio, and re-hypothecates idle liquidity to external yield sources.

Adds liquidity from configured yield sources immediately before each swap and removes it after, while adjusting fees via an EMA-based algorithm using updateDynamicLPFee.

It handles the entire swap in `beforeSwap` by computing quotes against its internal curve, taking input tokens into an Euler vault, and paying output tokens from another vault, returning a `BeforeSwapDelta` to bypass standard pool manager accounting.

All swap token flows are routed through Euler vault deposits and withdrawals rather than standard concentrated liquidity, with optional expiration-based temporal gating on swaps. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 9mo EulerSwapA Uniswap v4 hook implementing a custom AMM curve backed by Euler lending vaults. Fully replaces standard swap execution by depositing input tokens into and withdrawing output tokens from Euler supply/borrow vaults, with configurable fees and optional expiration. Arbitrum beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 9mo EulerSwapA Uniswap v4 hook implementing a custom AMM that routes swaps entirely through Euler lending vaults. In beforeSwap, it computes amounts via a custom bonding curve, takes input tokens and deposits them into Euler eVault positions, and withdraws output tokens from Euler eVaults — returning a full delta to bypass Uniswap concentrated liquidity. Supports optional pool expiration and protocol fees.

Fees are further adjusted ±10% based on current liquidity depth.

Liquidity addition is restricted to whitelisted addresses; accumulated sold tokens can be burned by the owner.
