PhoenixV4ReturnDeltaHook

ArbitrumRegistered

A return-delta hook for the Phoenix PXT/USDC pool that collects fees by adjusting swap deltas. Buys are charged a USDC skim; sells burn ~1.85% of PXT and skim USDC at a base rate, escalating to a penalty rate for large sells within a rolling window. Sell access is gated by a timestamp-based unlock and an anti-bot boolean cleared by the owner post-launch.

What it can do

Runs code on every swap

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

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

Gates who can add liquidity

It checks every deposit before it goes in.
