WTDLiquidityManager Contract

The WTDLiquidityManager contract manages Uniswap v4 liquidity pool positions for the WTD/USDC pair. It allows the admin to lock LP NFT positions for a specified duration (or eternally) and collect trading fees while the liquidity remains locked.

Key Features

• Position locking — Lock Uniswap v4 LP NFTs with a specified unlock time

• Eternal locks — Lock positions permanently (unlock time = max uint256)

• Fee collection — Collect accumulated trading fees without removing liquidity

• Pool verification — Only accepts positions from the correct WTD/USDC pool

Pool Configuration

The pool key is determined at deployment by sorting the WTD and USDC token addresses.
