ERC1967 upgradeable proxy for the Scale protocol, delegating hook logic to an upgradeable implementation. The proxy exposes beforeInitialize, beforeAddLiquidity, beforeRemoveLiquidity, beforeSwap, and afterSwap permissions; the implementation source is not verified, so swap behavior could not be fully analyzed.

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.
  • 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.
  • Can charge a different fee on each swapThe pool's LP fee is dynamic: the hook sets it, swap by swap.

Last test swap

A quote for a tiny exact-in swap each way through ETH / SCALE with Uniswap's V4 Quoter, compared with the pool's mid-price minus its 0.00% LP fee. It is an eth_call: nothing is signed or spent. Probed 3 h ago, every hour.
