According to CoinMeta, the public chain Katana acquired the business deployed on its chain by Sushi as well as VaultBridge, and integrated the spot and perpetual contract trading platforms. The project previously acquired IDEX in March. The transaction fees for spot and perpetual contracts flow to the Katana foundation, and the income generated from sorter fees and cross-chain asset lending on the Ethereum mainnet is also a source of revenue for them. The token economy model has been adjusted with these acquisitions and changes in revenue sources, and token pledgers will receive a portion of this income. (Source: fintech.tv)
