ReflectionV4Hook

EthereumRegistered

Reflection-fee hook: buys collect 1.7% ETH into a buyback pot; sells send 1.7% of token input to the token via notifyReflection(). Every 20 swaps a buyback is queued, run by a manual buybackAndReflect() call. One liquidity add per token; only exact-input swaps supported. afterSwap gates sells: anyone can call excludeFromReflections() to set reflectionBase[token], after which only canReflect addresses (managed by genesisAddress) can sell; only genesisAddress can disable it.

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.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
