Why Choose Katana?

Katana is more than just a yield platform—it’s your gateway to smarter, automated investment strategies. Built as an Ethereum Layer-2 (chain 747474), Katana combines deep liquidity, security, and real, sustainable yield for everyday DeFi users.

Real Yield, Not Just Emissions

VaultBridge puts bridged assets to work on Ethereum and AUSD adds U.S. Treasury yield, so returns are backed by real assets, not just token printing.

Deep, Unified Liquidity

Liquidity is concentrated across Sushi, Morpho and Yearn instead of scattered across pools, so trades stay deep and yields more stable.

Ethereum Security, ETH Gas

Katana is an Ethereum Layer-2 (chain 747474) that settles to Ethereum and pays gas in ETH, with no new trust assumptions.
