Uniswap V3

Uniswap V4

Edge Cases & Exploit Vectors

• Dust left in Uniswap V4 by the end of the callback will cause a revert

• You could maybe censor async actions by entering a callback on the pool before interacting with the victim protocol

• After a zeroForOne swap the active price can be exactly on a tick, but the activeTick will actually be the previous tick. This merely maintains the invariant that active price is ahead of activeTick, but may cause some issues with protocols — especially for 1 tick spacing pools!

• Sync DoS attack where either native or non-native tokens are donated and not synced, see L-13 Here

Checklist Items

• Hook functions should be permissioned for only the Uni Pool that uses that hook contract!
