Chainstack introduces Unichain support

We’re thrilled to announce that Chainstack now supports Unichain, the new OP Stack–based Layer 2 from Uniswap Labs, designed to solve DeFi’s biggest scaling and UX challenges head-on.

With this integration, developers can now deploy, scale, and optimize DeFi DApps on Unichain—backed by Chainstack’s high-performance, low-latency RPC infrastructure.

Why build on Unichain?

Unichain is a production-grade Layer 2 blockchain developed by Uniswap Labs and built on the OP Stack. It’s purpose-built to unlock the next evolution of DeFi by addressing core challenges around speed, cost, and fragmentation:

• Low cost, highly decentralized: Reduces transaction fees by ~95% compared to Ethereum L1 by moving execution to Layer 2—while preserving Ethereum’s decentralization model.
• Fast transactions, lower MEV loss: One-second block times at launch, with sub-250ms latency and TEE-enabled block building on the roadmap.
• Seamless cross-chain UX: Native interoperability via the Superchain and support for ERC-7683 enables simple, single-click swaps across L2s.

Unichain also introduces innovations like a decentralized validation network (UVN), support for Uniswap v4 hooks, and open-source architecture aligned with Ethereum’s long-term roadmap.
