[Katana Acquires Sushi's On-Chain Business and VaultBridge] DeFi public chain Katana has acquired Sushi's on-chain deployment business and VaultBridge, integrating its spot and perpetual contract trading platforms. The project previously acquired IDEX in March. Spot and perpetual contract trading fees flow to the Katana Foundation, while orderer fees and revenue generated from cross-chain asset lending on the Ethereum mainnet also contribute to its income. The token economic model has been adjusted following the acquisition and changes in revenue sources, with token stakers receiving a portion of these revenues. (Source: FINTECH.TV)
