Uniswap v4 hook for NFTX collection pools, pairing NFT collection tokens against a native token. Implements dynamic LP fees with per-address flat-fee exemptions, an optional AMM fee taken from the unspecified swap leg, pending-donation queuing for LP fee distribution, and a truncated-tick oracle; pool creation and lifecycle are restricted to the NFTX Locker contract.

What it can do to your swap

  • Can block swapsSwaps are gated (governance): only some addresses, or only at some times, can trade through it.
  • Can take a fee from your outputAfter the pool fills your swap, the hook can keep part of what you were about to receive.
  • Runs code before your swap and can block itThe hook is called before every swap. It can revert, which makes your swap fail.
  • Runs code after your swap and can block itThe hook is called after every swap. It can revert, which undoes your swap.
  • Can block LPs from withdrawingCalled before each withdrawal. It can revert, which stops liquidity providers from leaving.
  • Can block people from adding liquidityCalled before each deposit into the pool.
  • Runs code after liquidity is addedCalled after each deposit into the pool.
  • Runs code after liquidity is removedCalled after each withdrawal.
  • Runs code when a pool is createdCalled once, when someone creates a pool with this hook.
  • Can charge a different fee on each swapThe pool's LP fee is dynamic: the hook sets it, swap by swap.
