UpHook

BaseRegistered

Fee-collecting hook for ETH/token pools that deducts buy fees before the swap and sell fees after, splitting ETH proceeds among protocol, referral, and creator addresses. Restricts swap access to a trusted-router/quoter allowlist and tracks per-user token holdings for governance contribution attribution.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
