Uniswap v4 has accumulated $10.2 billion in total value locked in its first 30 days of operation, making it the fastest protocol in DeFi history to reach the milestone. The figure eclipses Uniswap v3's own 30-day record of $4.1 billion, set in May 2021.
The headline number is impressive, but the composition tells a more interesting story. Unlike previous versions, where the majority of liquidity sat in the ETH-USDC and ETH-WBTC pools, v4's TVL is spread across a longer tail of asset pairs — a sign that the new hooks architecture is enabling novel liquidity strategies.
What Are Hooks?
Uniswap v4's signature feature is the "hooks" system, which allows developers to attach custom logic to pool operations. Before a swap executes, a hook contract can run arbitrary code — adjusting fees dynamically, implementing TWAP oracles, or triggering liquidations in a lending protocol that uses the pool as collateral.
We built hooks because we recognised Uniswap cannot be everything for everyone. Instead, let developers extend the protocol. The TVL numbers suggest the market agrees.

The migration path from v3 has also been smoother than expected. Multiple protocols including Aave, Compound, and MakerDAO have shifted their primary liquidity pairs to v4 pools, attracted by the improved gas efficiency (around 15% cheaper per swap) and the new flash accounting model.
Whether the $10B figure holds will depend on incentive structures. Uniswap Foundation has committed $10 million in UNI grants to hook developers over the next six months, which should sustain developer activity. But absent a market-wide liquidity contraction, the trajectory looks strong.
