An OpenZeppelin ERC1967 transparent proxy pointing to an unverified implementation contract that contains the actual Uniswap v4 hook logic. The hook flags (beforeSwap, afterSwap, beforeSwapReturnsDelta, afterSwapReturnsDelta, and liquidity hooks) are encoded in the address bitmask, but the implementation source is not available for analysis.

What it can do to your swap

  • Its code can be replacedThe hook is a proxy (EIP-1967). Whoever controls it can swap in new code, so what it does today is not a promise for tomorrow.
  • Can take a fee from your outputAfter the pool fills your swap, the hook can keep part of what you were about to receive.
  • Can change the price you getBefore your swap runs, the hook can take or add tokens, so the amount you get is set by its code as well as the pool.
  • 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 when a pool is createdCalled once, when someone creates a pool with this hook.
