Uniswap Labs has unveiled a testnet for Unichain, the first Ethereum Layer 2 integrating Flashbots' Rollup Boost solution. This initiative joins a growing number of firms developing custom Layer 2 solutions.
According to a source, Uniswap Labs has extensive experience in liquidity and trading system development. A developer noted, "We are well positioned to enhance the cross-chain space regarding access and liquidity." The development from ideation to launch has been ongoing since last November, with significant progress made recently.
The Uniswap protocol, with a staggering $2.4 trillion in cumulative trading volume, will debut on the testnet chain, starting with V2 and V3. A preview of the highly anticipated Uniswap V4 is also set for launch by the year’s end, showcasing all audited features.
Unichain will leverage the Optimism Superchain, a scalable network of Ethereum Layer 2 solutions utilizing Optimistic rollups. This network allows various Layer 2s to share security and communication layers. A developer explained that introducing another Layer 2 within the Superchain could enhance native interoperability.
Hayden Adams, CEO of Uniswap Labs, expressed, "After years of building and scaling DeFi products, we’ve identified areas for blockchain improvement. Unichain aims to deliver speed and cost-efficiency while enhancing liquidity access across chains."
Uniswap's collaboration with MEV experts Flashbots integrates the innovative Rollup-Boost protocol. This middleware aims for one-second block times at launch, potentially achieving sub-second times in the future.
The Rollup Boost protocol optimizes transaction processing by streaming them to a trusted execution environment before they reach the sequencer. The developer explained the efficiency gained by organizing transactions into mini sub-blocks, significantly speeding up block creation.
Unichain, along with its block builder and node software, will be open source under the MIT license. The developer emphasized ongoing collaboration with the OP collective, aiming for open-source infrastructure development.
