Providing liquidity on decentralized exchanges can be a mixed experience. After depositing tokens and earning trading fees, liquidity providers often see arbitrage bots swiftly siphoning off profits, leading to the phenomenon known as impermanent loss. In response to these challenges, KyberSwap introduced FairFlow, a unique hook for Uniswap v4 designed to redirect a portion of arbitrage profits back to liquidity providers.
Since its launch on August 5, 2025, FairFlow has successfully generated over $3.2 billion in trading volume across 22 pools on various platforms including Ethereum and BNB Chain. This innovative solution operates by intercepting profits realized from inconsistencies between a liquidity pool and the broader market. Each time an arbitrageur takes advantage of price differences, FairFlow captures a portion of those earnings and redistributes them to the original liquidity providers.
The profit-sharing model is straightforward: liquidity providers receive 70% of the profits captured, while FairFlow retains 30%. These distributions occur weekly and are paid in the pool’s native tokens, with no additional staking required from the liquidity providers. They maintain their investments in the underlying Uniswap v4 pool while remaining free to deploy those tokens elsewhere for further potential earnings.
In terms of financial performance, FairFlow pools have seen a remarkable 21% annual percentage rate, which outperforms traditional Uniswap pools averaging around 16%. The project has also initiated several liquidity mining programs utilizing KNC, the native token of KyberSwap, offering rewards totaling hundreds of thousands of KNC to participants.
FairFlow's initial success was notable, with $1.4 billion in volume processed across 15 pools. Since then, it has more than doubled that throughput by adding seven additional pools. As of November 2025, FairFlow received a $50,000 grant from the Uniswap Foundation and gained exposure through its Hook Design Lab.
Understanding the significance of FairFlow reaches beyond the mechanics of one hook. The protocol has been audited by Omniscia and seamlessly integrates within Uniswap v4’s security framework, providing assurance that liquidity provider funds remain protected within the existing pool contracts.
While FairFlow does not completely eliminate impermanent loss, it does mitigate the impact of arbitrage extraction by returning a significant portion of earnings directly to liquidity providers weekly. This initiative offers a compelling option for those considering liquidity provision on Uniswap.
