Liquidity additions are blocked; all exchange is handled exclusively through the hook. Ethereum beforeInitbeforeAddLiqbeforeSwapswapDelta 1 18mo WETHHookWETHHook turns a v4 pool into an ETH / WETH wrapper. Swaps mint or burn WETH 1:1 against native ETH via the WETH9 contract. Deposits take ETH from the PoolManager and settle the minted WETH back; withdrawals unwrap and return native ETH. Direct liquidity provision is disabled.

Liquidity additions are restricted to an owner-managed LP allowlist. Ethereum beforeInitbeforeAddLiqbeforeSwap 1 19mo AutoWrapperA ghost pool hook that intercepts swaps between a base currency (e.g. USDC) and USDL, routing them through a liquid wUSDL/baseCurrency pool while automatically wrapping and unwrapping USDL↔wUSDL via an ERC4626 vault. Liquidity cannot be added to the ghost pool; only the configured router may initiate swaps.

The contract contains logic to apply time-based diminishing fees (stepping down through configurable fee tiers as time elapses since pool initialization), but the afterInitialize callback that records the initialization timestamp is commented out in the deployed code. As a result, the hook always returns the initial fee tier (feeTiers[0]) for all pools.

Liquidity additions are blocked; pools must be initialized with the wrapper/underlying token pair and zero fee.
