Chainstack introduces support for Katana

We’re excited to announce that Chainstack now supports the Katana network, a DeFi-first Layer 2 blockchain incubated by Polygon Labs and GSR, purpose-built to unify liquidity and deliver sustainable, real yield across decentralized finance.

With this integration, Web3 developers can now leverage battle-tested Chainstack infrastructure to deploy, test, and scale DeFi applications on Katana—with high-speed performance and no infrastructure friction.

Why build on Katana?

Katana is a production-grade Ethereum Layer 2 rollup tailored for DeFi. Built using a custom OP Stack (cdk-opgeth) and integrated with Polygon’s AggLayer, Katana aims to solve some of DeFi’s hardest challenges—fragmented liquidity, capital inefficiency, and yield sustainability. It offers:

• Unified DeFi liquidity: Native integrations with Sushi (DEX), Morpho (lending), and Vertex (perpetuals) to streamline access and amplify capital flow.
• Sustainable yield strategies: Yield is generated across lending, trading, and derivatives protocols—designed for long-term alignment.
• Advanced infra stack: Built with cdk-opgeth and OP Stack, connected to Polygon’s AggLayer, and enhanced with zero-knowledge proofs from Succinct SP1 and Plonky3.
• Governance via veKAT: The KAT token allows users to lock for veKAT to vote on protocol emissions and incentive structures.

For developers, it means building yield-driven dApps on composable, high-performance rails with deep liquidity by default.

Build better with Katana on Chainstack

Running Katana nodes is now seamless and high-performance with Chainstack. Whether you’re building a trading protocol, yield optimizer, or DeFi dashboard, Chainstack offers:

• Dedicated, performance-optimized Katana RPC infrastructure
• Flat-rate billing with no request-based fees or network surge pricing
• Full support for Katana’s OP Stack and ZK-proof integrations
