Uniswap Labs has rolled out its Ethereum-compatible layer-2 network, Unichain, following four months of testing and over 100 million settled on-chain transactions.
The team behind decentralized exchange Uniswap released the mainnet for its much-anticipated L2 network, Unichain, as announced by co-founder Hayden Adams on X on Feb. 11. The launch comes roughly two weeks after Uniswap v4 debuted in late January.
Uniswap built its layer-2 chain using Optimism’s OP Stack, a widely adopted blockchain development toolkit for decentralized finance applications.
By leveraging OP Stack, Uniswap has aligned with Optimism’s “Superchain” concept—a roadmap designed to advance rollup technology across web3 and the broader financial ecosystem. Leading crypto firms like Coinbase and Kraken have also used Optimism’s developer kit for their respective L2 chains, Base and Ink.
With the launch of Unichain, Uniswap Labs aims to enhance user experience, unify fragmented liquidity, and generate additional revenue through network fees. The company will reportedly collect about 20% of Unichain’s fees, helping to sustain its operations and development.
Unichain updates incoming
Adams described Unichain as a stage 1 rollup, meaning the network launched with some centralized components to ensure efficiency in its early phase. However, he hinted at plans to further decentralize the chain in the coming months.
“It only gets better from here,” Adams tweeted.
The Uniswap Labs co-founder also teased upcoming improvements, including Flashblocks, which will enable sub-second block times and improve transaction transparency.
Adams also mentioned working closely with Optimism to build collaboration with other L2s, making it easier to execute swaps, move liquidity, and experience DeFi. Unichain will leverage the Unichain Validation network for staking and blockchain security. The new L2 will channel 65% of its net revenue to UVN as an “additional layer of economic security and validation.”
According to Adams, Unichain launched with over 80 projects and processed more than 100 million transactions during its four-month testnet phase, which began in October 2024.
Uniswap’s new L2 will also integrate with Transak, a crypto on- and off-ramp service provider. The partnership will enable users to buy and sell digital assets via Transak’s payment infrastructure.
We believe that innovation lies at the intersection of accessibility and technology. Unichain’s vision to be a high performance rollup that scales Ethereum and powers DeFi complements our mission at Transak to make decentralized finance accessible to everyone.
