EBlockHook

EthereumRegistered

Enforces a fixed 2.5% ETH-denominated fee on swaps in a single configured pool, collected via beforeSwap and afterSwap return deltas. Token purchase amounts are tracked in transient storage for consumption by an external lottery/token contract. Fees accumulate and are distributed to the lottery contract via a permissionless `distributeFees()` call. The buyback executor is exempt from fee collection.

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.

Runs at pool creation

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