Polygon's DeFi-centric Layer 2 solution, Katana, has ascended to become the second-largest ZK rollup within the Polygon ecosystem, boasting a total value locked (TVL) of approximately $512 million. Co-founder Sandeep Nailwal underscored Polygon's pivotal role in promoting ZK proof technology and highlighted Katana's scalability as a DeFi chain. The forthcoming KAT token is set to enhance governance, provide liquidity incentives, and facilitate fee distribution, with initial allocations aimed at rewarding long-term participants. Katana's ecosystem includes integrations with DeFi applications such as Sushi, Morpho, and Vertex, supported by Polygon's Agglayer framework.
