What are hook warnings?

Hook warnings help liquidity providers to safely make informed decisions about adding hooks.

 

Any liquidity provider may add hooks to their pools at their discretion.

 

Our hook warnings check for properties that affect swapping, adding and removing liquidity, and donating to liquidity pools. These may have effects you are not anticipating, and there is potentially heightened risk in interacting with these hooks. Warnings are just one tool that provides extra information. Hook warnings are not investment advice or endorsements of a hook. Warnings are triggered based on the hook’s code, and are not a review or opinion from Uniswap Labs. Always do your own research.

 

Hook warnings are available on Uniswap v4 and supported Layer 2 networks.

How are hook warnings created?

Hook warnings are created based on the code of the hook. Uniswap Labs does not guarantee their accuracy and makes no representations or warranties about their relevance or currentness. Data frequently is not available for selected hooks, particularly newer or less popular hooks, and no hooks are reviewed for their quality, merits, or soundness as investments.
