Unichain Overview
Learn what Unichain is and how it supports faster, lower-cost onchain liquidity and cross-chain interoperability.
What is Unichain?
Unichain is a DeFi-focused Ethereum L2 designed for fast blocks, lower costs, and efficient onchain liquidity across chains.
Stage 1 rollup
Unichain is an Ethereum L2 with a permissionless fault-proof system designed for trust-minimized security.
Instant transactions
Unichain supports 1-second block times, with 200 ms preconfirmations available through Flashblocks. Lower latency improves market efficiency by increasing arbitrage frequency and reducing value lost to MEV.
Reduced costs and further decentralization
Unichain is designed to align with Ethereum's scaling roadmap by moving execution to an L2. This can reduce transaction costs significantly over time. While Unichain uses a sequencer for execution efficiency, full nodes can verify blocks independently.
Cross-chain liquidity
Unichain supports interoperability across multiple chains. As part of the Superchain, Unichain supports native interoperability and cross-chain liquidity access.
