Unichain: Efficient and scalable cross-chain DeFi layer 2 solution

In the thriving DeFi field, speed and scalability are crucial. Unichain is completely revolutionizing decentralized finance with its high-speed, low-cost cross-chain liquidity second-tier solution. Based on a powerful OP Stack and integrating Uniswap's innovative philosophy, Unichain integrates a decentralized blockchain ecosystem to create a seamless and efficient market for traders, developers and liquidity providers. Unichain has more than 9.5 million transaction records and a growing application ecosystem, and is leading a new era of decentralized transactions and finance.

Unichain: Development history and background

Unichain has been focusing on the DeFi field since its birth, committed to leveraging Ethereum's expansion roadmap to become a hub for cross-chain liquidity. As the first Ethereum L2 to be launched with Phase 1 Rollup and with a complete license-free proof of failure system, Unichain ensures secure and efficient transaction processing from the outset.

Key milestones:

• Vision and Origin: Founded by a team with extensive experience in decentralized transaction protocols, Unichain aims to significantly reduce transaction delays and costs while improving overall network efficiency.
• Technical breakthrough: Unichain's architecture adopts innovative design, utilizing OP Stack, achieving a block time of 1 second and plans to reach 250 milliseconds in the future to support high-frequency trading and arbitrage.
• Ecosystem Development: Over 80 application and infrastructure providers are built on Unichain to achieve seamless bridging, exchange, liquidity provision and stablecoin use, demonstrating Unichain’s important position as a modern DeFi infrastructure.

Technical Innovation and Architecture

Unichain takes scalability, efficiency and interoperability as its core principles. Its design not only makes full use of Ethereum's existing infrastructure, but also introduces innovative functions to continuously break through the limits of blockchain performance.

Superchain Architecture: Unichain is part of the grand vision of building a "superchain" - a global, decentralized protocol network. By integrating global computing power, Unichain reduces transaction delays and improves market efficiency. This superchain model is crucial to achieving a fast, low-cost transaction and a vibrant interconnected DeFi ecosystem.

Phase 1 Rollup: Safe and Efficient: As the first Ethereum L2 to adopt the first stage Rollup, Unichain uses a license-free fault proof system, which ensures security without affecting speed. This method ensures that every transaction is verified in a credible manner, effectively reducing potential bottlenecks and real-time processing.

Instant transactions: Unichain currently implements 1 second block time, significantly reducing latency and maximizing throughput. The network has been able to process thousands of transactions per second, and the future upgrade target is 250 milliseconds of sub-block time, which will redefine the transaction speed. This is crucial to reduce the MEV (miner extractable value) window and improve market efficiency.

Reduce costs and enhance decentralization: By shifting execution to Ethereum L2, Unichain reduced transaction costs by about 95%. This not only lowers the threshold for ordinary users, but also promotes decentralization. Although a single sorter is currently used to process transaction sorting to achieve maximum efficiency, the full node has the right to verify the blocks and gradually improve the degree of network decentralization and security.

Cross-chain liquidity and interoperability: Unichain aims to be the liquidity hub of multiple blockchain ecosystems. Its design promotes seamless cross-chain transfer, where users can transfer funds, exchange assets and access liquidity across chains without being restricted by native chains. As part of the hyperchain, Unichain supports native interoperability standards and works with Uniswap Labs and others to create a unified digital asset market.

Latest progress in Unichain

• Main Network Launch: Unichain Public Main Network was successfully launched on February 11, 2025, marking an important milestone in its development. The main network contains complete DeFi applications, cross-chain exchange and liquidity solutions, which consolidates its position as a center for multi-chain liquidity.
• Integration and Cooperation: Chainalysis has integrated with Unichain to enhance compliance and investigation workflows and enhance the security and trust of the ecosystem. Unichain is also a member of the Super Chain Collective, and cooperates with more than 25 interoperable L2 chains, including Base, OP Mainnet and Soneium, aiming to solve the problem of L2 chain fragmentation.
• Technical Advances: Unichain plans to use flash blocks to shorten block time to 250 milliseconds and introduce a decentralized validator network to further improve network security and finality.

Summary

Unichain is setting new standards for DeFi through a layer two innovation combining Ethereum's scalability and breakthrough. Its promise of instant, low-cost transactions and seamless cross-chain liquidity are changing the way liquidity is managed and traded in the crypto space.

Unichain, a DeFi native platform designed for large-scale adoption, not only provides traders and developers with excellent performance, but also lays the foundation for a truly connected blockchain ecosystem. Continuous upgrades and expanding functions will drive the next wave of DeFi innovation.
