Launched in June, 2025, Katana brings users, apps, and the network into alignment with an efficient DeFi flywheel. Katana deepens DeFi liquidity by concentrating it in a core set of apps and assets. This prevents fragmentation across competing DeFi primitives and improves user experience for both retail and institutions. The Katana vaultbridge generates yield with bridged assets and distributes that yield to ecosystem participants. vKAT, the staked version of KAT acts as the hub of the flywheel, directing yield emissions and earning fees from ecosystem apps.
