Polygon Labs and GSR Launch Katana, a DeFi-Focused Blockchain to Revolutionize Liquidity

Polygon Labs, in collaboration with GSR, has officially launched Katana, a new Layer-2 blockchain designed specifically for decentralized finance (DeFi). The Katana blockchain, incubated within Polygon’s ecosystem, aims to address the persistent issue of idle cryptoassets by prioritizing deep liquidity and high-yield opportunities for DeFi applications.

Katana, which debuted its private mainnet on May 28, 2025, opened its public mainnet today, marking a significant step toward reshaping the DeFi landscape. Built to integrate with Polygon’s AggLayer—a zero-knowledge (ZK)-powered interoperability framework—Katana is positioned as a “liquidity magnet” for the ecosystem, enabling seamless asset flows across connected chains. Unlike general-purpose blockchains, Katana focuses exclusively on optimizing select financial applications to minimize asset siloing and maximize capital efficiency.

“Katana is a paradigm shift for DeFi,” said a spokesperson from Polygon Labs. “By aligning applications, users, and chain revenue from day one, we’re creating a purpose-built environment that tackles inefficiencies in liquidity and yield generation.”

The blockchain leverages advanced technology from Succinct Labs for its ZK-proof infrastructure, ensuring fast, secure, and scalable transactions tailored for institutional-grade DeFi solutions. Katana’s compliance-aware design includes features like permissioned issuance and real-market liquidation routes, setting it apart from experimental or speculative DeFi protocols.

Backed by Polygon Labs and GSR, a leading crypto market maker, Katana aims to attract both retail and institutional participants. The platform has already enabled pre-deposits, encouraging users to activate idle assets for higher yields.

Users are describing Katana as a “DeFi chain forged to kill idle assets” and a potential game-changer for sustainable yield generation. However, Katana’s launch follows a controversial backdrop. According to discussions on X, the project emerged after a failed proposal to repurpose assets held in Polygon’s bridge, which led to backlash and reportedly prompted Aave to abandon Polygon’s ecosystem.

Despite this, Katana’s focused approach and integration with AggLayer have positioned it as a promising contender in the DeFi space. With its public mainnet now live, Katana is set to drive innovation by offering a robust, liquidity-centric platform for DeFi applications.
