Polygon’s Big ZK Gamble Is Starting to Show Real DeFi Numbers Through Katana

Polygon’s growing investment in zero-knowledge (ZK) technology is yielding tangible results. Co-founder Sandeep Nailwal highlighted Katana, a DeFi-focused Layer 2, as one of the largest ZK rollups within the Polygon ecosystem. In a post on X, Nailwal emphasized Polygon's “big role” in championing ZK proofs, with its Agglayer connecting multiple ZK rollups into a scalable framework. ZK proofs are becoming critical for blockchain privacy and scalability, and Nailwal expressed pride in Polygon’s contributions to this advancement.

Over the years, Polygon has established itself as a leader in ZK scaling solutions, with significant investments in rollups and interoperability frameworks. This focus is evident in Polygon Agglayer. Katana, in particular, has risen to prominence as the second-largest ZK rollup in terms of DeFi total value locked (TVL), with approximately $512 million TVL, according to DefiLlama. This places Katana 15th among Layer-1 and Layer-2 chains, trailing only major ecosystems such as Aptos and Avalanche.

From its theoretical roots in the 1980s to practical applications today, ZK technology has evolved rapidly, as noted by data from a16z crypto. Advances from SNARKs and STARKs to newer zkDSL systems have unlocked tools like privacy-preserving transfers, trustless rollups, and fully on-chain DeFi solutions. Katana exemplifies this progress, serving as a live and liquid DeFi chain that signals ZK technology’s readiness for real-world deployment. Builders are leveraging these advancements for scalable and privacy-focused blockchain solutions.

At the center of Katana’s ecosystem is its native token, KAT, which is essential for governance, liquidity incentives, and fee distribution. With a total supply of 10 billion units and a nine-month initial transfer lock, KAT emphasizes ecosystem sustainability. Early distribution targets long-term ecosystem participants such as POL stakers and Krates vault depositors. Katana’s robust DeFi apps, including Sushi for spot trading and Morpho for lending, strengthen its network with Chain-Owned Liquidity to stabilize markets.

As the KAT token launch approaches, Polygon’s ZK-first strategy and Katana’s infrastructure support position it as a major player in the next wave of scalable DeFi ecosystems. Early liquidity programs, strong technological backing, and integration with top DeFi tools ensure Katana’s growth trajectory. With its focus on scalability and privacy, Katana is expected to significantly impact blockchain ecosystems in the near future.
