UNISWAP V4 · SWAP REBATE HOOK

What the hook

Trading creates a temporary price divergence between two pools. The hook captures it before external bots do — and returns part of it to the trader, and the rest to the liquidity providers.

SEE HOW IT WORKS

How it works

The mechanic end to end: capture before outside bots, then the share-out.

The user flow

Step by step, with the buy and sell splits. The fine print is the honest part.

Bring your own token

The integration path, and how the liquidity share divides across the four pools.

The WTH token

Shares of positive captured profit — not percentages of the trader's full trade amount.

It also looks at v3

The hook does not only compare its own two pools. It detects v3 pools holding the same base token and arbitrages against those as well.

More venues to compare against means more divergence available to capture.

How it is built

A smaller, clearly separated system is easier to test, audit and pause.

At a glance

The whole loop, start to finish.

WTH — What the hook

Better trader economics and higher LP returns — which can attract more volume and more liquidity.
