Uniswap Labs has officially launched Uniswap v4, marking a major evolution in decentralized exchange (DEX) technology. Now live across 10 major blockchains—including Ethereum, Polygon, Arbitrum, OP Mainnet, Base, BNB Chain, Blast, World Chain, Avalanche, and Zora Network—this latest version redefines what’s possible in automated market maker (AMM) systems by introducing unprecedented levels of customization and efficiency.
Designed as both a trading platform and a developer-first infrastructure, Uniswap v4 sets a new benchmark for flexibility, gas optimization, and innovation in the DeFi ecosystem.
A New Era for Decentralized Finance
Uniswap v4 transforms the protocol from a simple swap engine into a fully programmable financial platform. At the heart of this transformation are hooks—modular smart contract plugins that allow developers to embed custom logic directly into liquidity pools. These hooks enable dynamic fee models, automated liquidity management, time-weighted average pricing (TWAP), and even integration with external protocols.
With over 150 hooks already developed, the community is rapidly expanding the functionality of Uniswap beyond basic token swaps. Developers can now build self-rebalancing pools, limit orders within AMMs, and permissioned liquidity strategies—all without forking the core protocol.
“Uniswap v4 is here🦄
Users can LP on v4 through the Uniswap web app and swapping is rolling out over the coming days as liquidity migrates to v4”

This modular architecture accelerates development cycles, encourages experimentation, and strengthens network effects by enabling deeper integrations between DeFi applications.

Enhanced Efficiency Through Gas Optimization
One of the most impactful upgrades in Uniswap v4 is its dramatic reduction in gas costs. Creating a new liquidity pool on v4 is up to 99.99% cheaper than in previous versions, thanks to a consolidated singleton contract design that minimizes redundant deployments.
For traders, especially those executing multi-hop swaps across multiple pools, gas fees are significantly lower due to optimized routing and reduced overhead. Additionally, native ETH support eliminates the need for wrapping ETH into WETH when trading or providing liquidity, further cutting transaction costs and simplifying user experience.
These efficiency gains make it economically viable to deploy niche or low-volume pools that were previously impractical under v2 or v3, opening the door for long-tail asset trading and specialized financial products.
Seamless Access Across Chains and Interfaces
Uniswap v4 is now active across 10 leading blockchains, reflecting Uniswap Labs’ commitment to multi-chain interoperability. Whether you're on Ethereum, Arbitrum, Base, or Avalanche, access to v4 liquidity is built directly into all official Uniswap products.
Users don’t need to take any special steps to benefit from v4. Swaps will automatically route through the most efficient available pools—including v2, v3, and v4—via UniswapX, the protocol’s advanced order-matching system. This ensures optimal pricing and minimal slippage without requiring manual intervention.
Liquidity providers (LPs) have two options:
- Migrate existing positions from v3 to v4
- Create new v4 pools with custom hooks enabled
To get started, LPs simply select “v4” on the liquidity provision page and input the desired hook address. Full documentation and developer resources are available for teams looking to build or integrate their own hooks.
Built for Security and Transparency
From day one, Uniswap Labs prioritized security in the development of v4. The full contract code was made public early in the process, inviting open collaboration and peer review from the global developer community. This transparent approach led to hundreds of pull requests and valuable feedback from independent contributors.
Before deployment, the codebase underwent rigorous testing:
- Nine formal audits of core and peripheral contracts
- A $2.35 million security competition with over 500 participants
- The largest bug bounty program in DeFi history—offering up to $15.5 million for critical vulnerability reports
Critically, no high-severity bugs were discovered during either the competition or bounty period. The bug bounty remains active post-launch to ensure ongoing vigilance and encourage responsible disclosure of potential issues.
This multi-layered security model underscores Uniswap’s commitment to trustless, resilient infrastructure.

Q: What are hooks in Uniswap v4?
A: Hooks are smart contract plugins that allow developers to add custom logic to liquidity pools—such as dynamic fees or auto-rebalancing—making Uniswap highly extensible.
Q: How much cheaper is pool creation in v4 compared to earlier versions?
A: Creating a new pool in v4 is up to 99.99% cheaper in gas costs due to a streamlined singleton contract architecture.
Q: Can I migrate my v3 liquidity to v4?
A: Yes, existing LPs can migrate their positions from v3 to v4 directly through the Uniswap web app interface.
Q: Was Uniswap v4 audited?
A: Yes, the protocol underwent nine formal audits, a large-scale security competition, and maintains an ongoing bug bounty program with rewards up to $15.5 million.
The Future of Programmable Liquidity
Uniswap v4 isn’t just an incremental upgrade—it’s a foundational shift toward programmable liquidity. By empowering developers with tools like hooks and gas-efficient deployment, Uniswap Labs has created a platform where innovation can happen at the protocol level without compromising decentralization or security.
As more builders leverage these capabilities, we can expect to see new financial primitives emerge: pools that adjust fees based on volatility, automated market-making strategies integrated with lending protocols, and even NFT-based liquidity positions.
The open nature of the ecosystem invites continuous experimentation, ensuring that Uniswap remains at the forefront of DeFi innovation.
