New blockchain aims to address liquidity fragmentation and unsustainable yield challenges.
Polygon Labs, in partnership with the crypto trading firm GSR, has launched Katana, a new Ethereum-based Layer 2 blockchain designed to address key challenges in decentralized finance (DeFi).
The mainnet went live on July 1, 2025, with over $240 million in pre-deposits, marking a significant milestone in the DeFi ecosystem.
What is a Katana?
According to an official statement, Katana aims to address two major challenges in DeFi: unsustainable yields caused by token inflation and the fragmentation of liquidity across multiple blockchains and applications.
Unlike blockchains that prioritize broad accessibility, Katana focuses on select financial tools and encourages users to deposit their crypto into these curated platforms.
This approach includes integration with Morpho, a lending protocol managing over $6.5 billion in deposits, and a built-in decentralized exchange based on SushiSwap.
VaultBridge: The Core Innovation
At the heart of Katana’s model is VaultBridge, a protocol that redirects idle crypto assets to secure lending pools, generating yield that is shared across Katana’s chosen financial apps.
After being returned, these assets are placed into low-risk lending and borrowing pools on Morpho, overseen by risk advisors like Gauntlet and Stakehouse Financial. The earnings from these pools are then sent back to Katana and shared among its selected financial platforms.
Additionally, Katana includes several DeFi features, such as a customized Sushi DEX, Morpho’s lending platform, a memecoin launchpad, and a decentralized perpetuals exchange.
Project leaders say major platforms like Aave and Uniswap will struggle to compete within Katana’s tightly controlled ecosystem, which concentrates capital and favors selected protocols.
Governance Model
Unlike most Layer 2 chains governed by token holders, Katana will be managed by the nonprofit Katana Foundation with partners from Polygon, GSR, and Conduit.
A nine-member steering committee handles governance, while a 13-member security council has emergency powers. The network’s native Katana token (KAT) won’t grant governance rights.
Polygon Labs sees Katana not as a competitor but as a complement to Polygon POS. While Polygon POS focuses on stablecoins and real-world assets, Katana caters to traders and financial applications within the Ethereum ecosystem.
Both share an underlying architecture that enables seamless asset transfers, supporting a range of fintech solutions. Katana is designed to meet growing institutional demand for yield and savings products, positioning itself as a blockchain optimized for the next phase of DeFi.
Before launch, Katana attracted over $200 million in deposits, highlighting significant demand for its yield-focused and specialized DeFi platform.
Why This Matters
Katana’s launch marks a move toward more efficient and sustainable DeFi by concentrating liquidity in vetted platforms to tackle yield inflation and fragmented markets, key barriers to broader adoption.
