Supports per-swap vault overrides via hookData, with owner-configurable per-pool defaults.

Fees are verified on-chain via a Lit Network signature and then published to pools via `poolManager.updateDynamicLPFee()`. The `beforeInitialize` hook enforces that only dynamic-fee pools (fee = 0x800000) can use this hook.

In beforeSwap, it computes swap output via a curve invariant (CurveLib), deposits input tokens into an Euler vault, and withdraws output tokens from another vault, fully handling the exchange itself. Unichain beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 13mo AssetToAssetSwapHookForERC4626Periphery hook for pools using ERC4626 vault wrapper tokens. In beforeSwap, converts input ERC20 assets to vault wrapper shares, performs a nested swap in the corresponding vault wrapper pool via poolManager.swap(), then redeems output shares back to underlying assets. Handles both exact-input and exact-output swaps. Vault wrappers can be supplied via hookData or configured as per-pool defaults by the owner. Unichain beforeAddLiqbeforeSwapswapDelta 1 13mo YoyoStrategyHookA fee-taking hook that charges a time-decaying fee (starting at 26%, decreasing 200 bps every 25 blocks) on all swaps, taken from the output token via afterSwapReturnsDelta. When the fee currency is WETH, a 100% fee is applied instead. Non-ETH fees are converted to ETH via a nested pool swap and forwarded to a designated fee address.

Users deposit ERC-20 tokens by adding liquidity with a cryptographic commitment, and withdraw by submitting a ZK proof (Circom Groth16 or Noir Honk) against a Merkle tree root, with fees redistributed to the pool.

In beforeSwap it deposits liquidity at active tick boundaries, and in afterSwap removes all liquidity and settles token balances, with a dynamic LP fee updated on rebalance and a price-deviation circuit breaker that reverts swaps exceeding a configured threshold.

Instead of using Uniswap v4's concentrated liquidity, it routes swaps entirely through its own bonding curve: depositing input tokens into an Euler vault and withdrawing output tokens from another, then verifying the resulting reserves satisfy the curve invariant. Unichain beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 14mo EulerSwapA custom AMM hook that routes swaps through Euler Finance vaults. It fully overrides Uniswap v4 swap execution via beforeSwapReturnsDelta: input tokens are deposited into an Euler vault and output tokens are withdrawn from another, with reserves tracked against a custom bonding curve invariant verified by CurveLib. Unichain beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 14mo EulerSwapA Uniswap v4 hook implementing a custom AMM backed by Euler lending vault positions. In beforeSwap, it intercepts every swap, computes amounts via a configurable price curve, and routes funds through Euler vaults, returning a BeforeSwapDelta to bypass pool-native pricing. Adding CLAMM liquidity and donations are blocked to protect against unproductive positions. Unichain beforeInitbeforeAddLiqbeforeSwapbeforeDonate+1 1 14mo EulerSwapA custom AMM hook that implements single-LP pools backed by Euler Finance lending vaults. In beforeSwap, it fully processes each swap by depositing input tokens into and withdrawing output tokens from Euler vaults, returning a BeforeSwapDelta to bypass Uniswap's native liquidity math. Reverts on direct liquidity additions and donations to enforce the custom curve invariant.
