Uniswap v4 Hooks Explained — And What We Built for OnChain Revenue Sharing

Description and use

BatchDistributeHook enables Uniswap v4 pool operators to distribute revenue to up to 200 recipients in a single on‑chain transaction via Spraay’s batch contract, simplifying and speeding up payouts.

Problem

Pool operators needed a way to distribute accumulated fees or revenue to many stakeholders in a single on‑chain transaction.

Outcome

BatchDistributeHook enables efficient, verifiable on‑chain revenue sharing for Uniswap v4 pools, reducing operator effort and transaction costs.

Workflow

• Create a pool with BatchDistributeHook as its hook contract
• Operate the pool normally (swaps, liquidity, etc.)
• When ready to distribute, call the hook’s distribute function
• Hook approves Spraay batch contract to spend the specified token amount
• Spraay batch contract executes a single transaction that transfers tokens to all recipients
• Recipients receive their shares on‑chain and can verify the settlement

Evidence

Uniswap v4 introduced one of the most significant architectural changes in DeFi: hooks.
