Polygon-Backed Katana Blockchain Launches Private Mainnet to Unlock Institutional DeFi Yields

Polygon (POL)

Katana Foundation launched the private mainnet of its DeFi-optimized blockchain, backed by GSR Markets and Polygon Labs. Designed specifically to address liquidity fragmentation—a persistent issue in decentralized finance—Katana concentrates liquidity across major protocols to provide more predictable lending, borrowing, and trading conditions.

Polygon Labs CEO Marc Boiron, a key contributor to Katana, emphasized the project’s mission to create “a truly positive-sum environment for builders and participants alike.” With its public mainnet scheduled for June, Katana aims to serve as an institutional gateway into DeFi by offering sustainable, compounded yield opportunities.

Boosting Yield Through Optimized Liquidity Infrastructure

Katana integrates a wide array of DeFi protocols—such as lending platform Morpho, decentralized exchange Sushi, and perpetual DEX Vertex—into one ecosystem. Through VaultBridge, bridged assets are deployed into overcollateralized lending strategies on Ethereum, earning yield that is then returned and compounded on Katana.

“Yield is distributed pro-rata to each chain using the VaultBridge protocol,” said Boiron. “If Katana supplies 20% of total vault deposits, it receives 20% of the yield back.” These returns are then redistributed across Katana’s core applications, offering users boosted DeFi incentives based on real Ethereum-based yield sources rather than inflated token emissions.

Meeting Institutional Demand with Scalable, Sustainable DeFi

As institutional interest in DeFi accelerates—projected to rise from 24% to 75% by 2027 according to EY-Parthenon—Katana is strategically positioned to meet the growing need for reliable, compliant yield. The blockchain also incorporates Chainlink’s decentralized oracle network and Conduit’s sequencing layer to ensure performance, transparency, and data integrity.

In an environment still fraught with regulatory uncertainty—flagged as the top barrier to entry by 57% of institutional investors—Katana offers a stability-focused, long-term solution. By reinvesting protocol revenue and avoiding mercenary capital tactics, Katana is redefining what sustainable yield in DeFi can look like.

With deep liquidity, real yield mechanisms, and backing from Polygon Labs, Katana could become a key player in the next phase of institutional DeFi adoption.
