Kamino, a DeFi platform on Solana, has introduced PT-USX on the Solstice Market, offering a fixed yield of 16.5% APY. This principal token, issued by Exponent Finance, complements Kamino's existing fixed-yield offerings and can be used as collateral for borrowing USX or USDC. The initiative aims to bolster Solana's stablecoin-driven fixed-income ecosystem, with PT-USX set to mature on February 9, supporting leveraged looping strategies. Exponent Finance, known for its audited protocol, structures yield-bearing assets into Principal Tokens (PTs) and Yield Tokens (YTs), providing users with predictable returns. This launch is part of Kamino's strategy to enhance the DeFi landscape on Solana by expanding its stablecoin and fixed-income product offerings.
