Polygon Labs and crypto market maker GSR have jointly launched the Ethereum second layer blockchain Katana with DeFi as its core, aiming to solve the problem of on chain asset fragmentation and unsustainable returns driven by high inflation. Katana adopts a centralized filtering mechanism that only supports a few financial applications, and uses the VaultBridge protocol to transfer user assets back to Ethereum's Morpho protocol for low-risk lending. The profits obtained are then returned to Katana to improve the profitability of key applications. （DL News） https://www. (wublock123.com)/index.php? m=content&c=index&a=show&catid=6&id=44818
