Katana is redefining the value of idle assets. When USDC, USDT, and ETH are left dormant for the long term, they generate no returns — a legacy inefficiency from traditional finance. By deploying these stablecoins and mainstream assets into on-chain strategies, Katana transforms passive holdings into active sources of income.

But this is only the first layer. True innovation occurs at the second layer. Spectra Finance introduces the Principal Tokens (PTs) mechanism, achieving a separation of yield and principal — users can independently trade, hedge, or combine these two parts, rather than being forced to hold the entire position. This design breaks the traditional single-mode approach of DeFi yield products, making capital allocation more flexible and efficient. This not only changes how users earn returns but also redefines the possibilities of on-chain finance.
