Unichain is a DeFi-native Ethereum Layer-2 blockchain, built to be the home for liquidity across chains. ^[1][2]

Overview

Unichain is an optimistic rollup optimized for efficient markets by delivering efficient state updates, offering a framework for applications to internalize MEV (maximal extractable value), and providing an economic finality system for quick settlement across blockchains. ^[4]

Launched on October 10, 2024, the development of Unichain is a collaborative effort across many organizations: Uniswap Labs - is the primary technical provider for Unichain and operates the Unichain Sequencer and Uniswap Foundation - provides grants and support for developers. ^[3]

Unichain includes open-source code contributions from Optimism, Flashbots, and Paradigm research teams. ^[3]

Unichain, including the block builder and node software, is open source (MIT licensed) and available for other chains to adopt. ^[5]

The chain is said to provide instant transactions, reduced cost and further decentralization, and cross-chain liquidity. ^[6]
