SidechainHook

EthereumRegistered

A Uniswap v4 ETH/BPM pool hook that functions as an on-chain music sequencer, mapping each swap to a rhythmic note on a 16-measure grid. It applies dynamic protocol fees based on beat position, accumulates fees per track, and tracks player groove scores; at track close the score leader is crowned winner and fees are handed to an immutable fee vault for a BPM buyback.

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.

Sets its own swap fee

Pools using it let the hook choose the swap fee instead of a fixed tier.

Runs at pool creation

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