Uniswap Launches Unichain Mainnet

Developers at Uniswap Labs have announced the launch of the Unichain mainnet, an Ethereum layer-two solution.

Project founder Hayden Adams explained to The Block that Unichain will not only provide a dedicated network for one of the largest DEXs but also partially address the fragmentation issue within the Ethereum ecosystem.

“In my opinion, many different applications should exist on different chains. If anyone can benefit from having their own chain, it’s Uniswap,” he noted.

The new solution is primarily targeted at DeFi projects. Adams noted that, like other L2 networks, Unichain can be used for any scenario, but there are certain technical features that make it particularly suitable for the decentralized finance segment.

The Unichain network is built within the Superchain ecosystem by Optimism, based on the OP Stack. Uniswap Labs is responsible for technical support and managing the Unichain Sequencer while the Uniswap Foundation funds its development.

Initially, block processing time in Unichain is promised to be around one second. Developers plan to reduce this to 250 ms over the coming months by implementing the Rollup-Boost mechanism.

According to Adams, the update will bring “incredible benefits” to liquidity providers and other market participants through “new forms of arbitrage and limiting the negative impact of MEV.”

“The greater the gap, the more time per block, the more MEV accumulates,” the developer emphasized.

Since its launch, Unichain has also included a system for prioritizing operations to prevent execution order manipulation and a mechanism for disputing problematic transactions.

The UNI token will be used for validation in the Unichain Validation Network while maintaining its role in governance. The developer added that the issue of sharing protocol profits with token holders remains outside the focus of Uniswap Labs.

Validators and stakers will receive 65% of Unichain’s total revenue.

Adams emphasized that these innovations reduce the significance of a centralized Unichain sequencer.

“Sometimes people have a contrived concept: ‘the sequencer is centralized, we need to decentralize it,’ but they don’t turn this into a real solution, thinking about it abstractly,” the developer noted.

In his view, if a user does not wish to trust such a system, “they can wait for the transaction to be confirmed by the validator network.” Over time, the need for a sequencer “will fade away,” he hopes.

Adams believes the new network could become a unifying layer for many L2 solutions:

“Both at the blockchain level and at the interface level in our products, we aim to become a cross-chain liquidity hub.”

LayerZero has become one of the first interoperability providers in Unichain.

According to the developers, their protocol connects participants from over 120 networks to the solution.

On January 31, the Uniswap v4 protocol update was released with support for 10 blockchain networks.
