Polygon’s growing bet on zero knowledge technology has started to show concrete results as co-founder Sandeep Nailwal drew fresh attention to Katana, a DeFi focused Layer 2 that is now one of the largest ZK rollups in the Polygon environment.

In a post on X, Nailwal talked about how Polygon has played a “big role” in the adoption of ZK proofs, adding that Polygon’s Agglayer connects multiple ZK rollups into one scalable framework. 

Polygon’s ZK Stack Is Now Producing High TVL Rollups

Over the past few years, Polygon has positioned itself as a leader in zero-knowledge scaling solutions, investing heavily in ZK rollups and interoperability infrastructure.

That focus is now materializing through Polygon Agglayer. Among these, Katana stands out, currently ranked as the second-largest ZK rollup by DeFi total value locked (TVL), trailing only Linea, according to DefiLlama.

With around $512 million in DeFi TVL, Katana ranks 15th overall among Layer-1 and Layer-2 chains, only behind established ecosystems like Aptos, Avalanche, and Sui.

ZK Tech Has Moved From Theory to Polygon-Ready Rollups

Data from a16z crypto shows how ZK technology has evolved from theoretical models in the 1980s to practical, recursive implementations driving blockchain scalability today.

From early proof systems such as SNARKs and STARKs to newer transparent systems and zkDSLs, the sector has moved fast. That speed unlocked real products such as privacy preserving transfers, trustless rollups and fully on chain DeFi that does not leak user data.

Katana is being framed as the latest expression of that progress because it is a DeFi chain that is live, liquid and part of an aggregation layer. This tells builders that ZK is now deployment ready rather than experimental.

KAT Token Will Lock In Governance, Fees and DeFi Liquidity

At the center of Katana’s growth is its upcoming native token, KAT, which forms the heart of governance, liquidity incentives, and fee distribution. The token’s design emphasizes sustainability and ecosystem health, with a total supply of 10 billion units and an initial nine-month transfer lock.

Early distribution has targeted long-term participants, including POL stakers, early depositors in Krates vaults, and users engaging with Turtle Club’s on-chain yield programs.

Katana’s ecosystem features integrated DeFi apps like Sushi for spot trading, Morpho for lending, and Vertex for perpetuals, supported by Chain-Owned Liquidity to stabilize markets and minimize volatility.

As the KAT token launch approaches, strong infrastructure backing, early liquidity programs, and Polygon’s ZK-first vision puts Katana as a major contender in the next wave of scalable DeFi ecosystems.
