The launch of Uniswap v4 has taken place across various blockchain networks, with swapping functionalities expected to roll out to all users shortly.
Uniswap Labs, the organization responsible for the decentralized exchange Uniswap, has revealed that its fourth-generation protocol is now accessible to the public. This upgrade brings enhancements aimed at improving developer usability and on-chain liquidity.
As stated in a company blog post, Uniswap v4 is operational on Ethereum, Polygon, Arbitrum, OP Mainnet, Base, BNB Chain, Blast, World Chain, Avalanche, and Zora Network as of January 31.
The firm had originally intended to launch v4 last year. Nevertheless, delays were encountered due to thorough code audits for security assurance and multiple hackathons aimed at stress-testing the protocol’s code. Additionally, the team audited the v4 code nine times and issued a $15.5 million bug bounty to address any remaining architectural issues.
Among the prominent upgrades in Uniswap v4 are the addition of “hooks” and the singleton liquidity design. Hooks particularly captured interest when v4 was unveiled, as the upgrade promises to convert Uniswap into a developer-centric decentralized application.
The Labs describe Hooks as blockchain contracts designed to facilitate custom architectures for liquidity pools, on-chain swaps, and cryptocurrency fees. Hooks complement the singleton liquidity framework, which consolidates Uniswap liquidity into a unified smart contract.
Uniswap engineers have indicated that the new liquidity architecture is expected to lead to lower transaction costs and quicker swaps, thereby enhancing the user experience.
More than 150 hooks have already been created, offering functionalities that range from dynamic fees to automated liquidity management. By empowering developers to construct and experiment directly on the protocol, hooks facilitate swifter development cycles and more robust integrations.
