What is Katana?
Katana is an Ethereum-aligned Layer 2 blockchain built on Polygon CDK, purpose-designed for yield-focused DeFi. It leverages Agglayer as its canonical bridge and VaultBridge to deploy bridged assets into Ethereum yield strategies, concentrating liquidity for reliable returns.
Governance involves two multisigs: Katana Admin (3-of-5 for upgrades) and the DeFi Security Council (10-of-13 for security oversight). This structure provides efficient governance, zero-knowledge proof security, and optimized liquidity allocation, boosting yield in core DeFi protocols like Morpho and Sushi.

Final Thoughts
Integrating Katana with MetaMask is straightforward, either manually or through ChainList, offering immediate access to its yield-focused DeFi environment.
Before connecting, always verify network settings via Katana's official docs. For developers, Tatara testnet provides a safe environment to explore functionalities.
