币界网报道:Polygon Labs and crypto market maker GSR jointly launched Katana, a DeFi-centric Ethereum layer 2 blockchain, to solve the problem of asset fragmentation and unsustainable returns driven by high inflation. Katana adopts a centralized screening mechanism, supports only a few financial applications, and returns user assets to Ethereum's Morpho protocol for low-risk lending through the VaultBridge protocol. The income is then returned to Katana to improve the income level of key applications.
