Two separate Solana-based product launches highlight expanding onchain fixed-income-style and yield infrastructure. Kamino has launched STRCx on Kamino Multiply, allowing users to access up to 2x leverage on Strategy’s tokenized STRC preferred stock through a dedicated lending market, with monthly rebasing and an 11.5% annualized dividend, according to the announcement. Separately, Exponent Finance has launched its V2 upgrade on Solana, expanding from an interest rate swap venue into what it describes as an institutional-grade platform for onchain yield management by adding a rate order book, a Rate CLMM, Strategy Vaults, and risk tranching swaps. Together, the announcements show Solana-based decentralized finance platforms introducing more structured products tied to tokenized assets, rate pricing, liquidity management, and segmented risk.
