If you’ve ever provided liquidity on a decentralized exchange, you’ve probably experienced a familiar sting. You deposit tokens, earn some trading fees, and then watch arbitrage bots extract value from your position faster than you can say “impermanent loss.” FairFlow, a Uniswap v4 hook built by KyberSwap, launched roughly a year ago with a simple pitch: what if those arbitrage profits went back to you instead?
Since its August 5, 2025 launch, FairFlow has facilitated over $3.2 billion in trading volume across 22 pools spanning Ethereum, Base, Arbitrum, Monad, and BNB Chain.
How the plumbing actually works
FairFlow operates as a “hook” on Uniswap v4, the modular upgrade to Uniswap that lets developers attach custom logic to liquidity pools. When an arbitrageur extracts value from a price discrepancy between a pool and the broader market, FairFlow intercepts a portion of that profit and routes it back to the people who supplied the liquidity in the first place.
The split is 70/30. Liquidity providers receive 70% of the captured EG, while the platform retains 30%. Distributions happen weekly and arrive in the pool’s native tokens. LPs don’t need to stake anything extra. Their funds remain in the underlying Uniswap v4 pool, and they can deploy those same tokens elsewhere for additional yield.
The returns so far
FairFlow pools have generated approximately 21% APR compared to around 16% for standard Uniswap pools.
The project has also run multiple liquidity mining programs using KNC, KyberSwap’s native token, with reward tranches of 500,000 KNC and 200,000 KNC distributed to participating LPs across phases running from May through July 2026.
FairFlow’s earlier milestone showed $1.4 billion in volume across 15 pools, meaning the protocol has more than doubled its throughput while adding seven additional pools since that point.
In November 2025, the Uniswap Foundation awarded FairFlow a $50,000 grant and featured the project in its Hook Design Lab.
Why this matters beyond one hook
FairFlow has been audited by Omniscia and operates within Uniswap v4’s existing security framework, meaning LP funds are held in the same pool contracts rather than being transferred to a separate custody layer.
For investors evaluating whether to provide liquidity on Uniswap, FairFlow doesn’t eliminate impermanent loss, but it does reduce the arbitrage extraction component by returning 70% of captured arbitrage value directly to LPs weekly in the pool’s native tokens.
