BTC ACC Hook (Base)

BaseRegistered

A hook that takes a configurable fee (1-10%) on each swap and deposits it into a Bitcoin accumulation contract, converting swap fees from ETH, WETH, USDC, or cbBTC into Bitcoin for the swapper. The beforeInitialize hook enforces that pools must pair exactly one allowed base token (ETH/WETH/USDC/cbBTC) with a non-base token.

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.
