# Introduction to Port Finance Port Finance is a non-custodial money market protocol on Solana. Its goals are to bring a whole suite of interest rate product including: variable rate lending, fixed rate lending and interest rate swap to the Solana blockchain. The current variable rate product features variable interest rates based on supply & demand, cross collateral lending, and flash loans. The fixed-rate lending product uses the model of zero coupon bond. We allow lender to lend at a fixed rate and allow borrower to take on fixed-rate, fixed-term loan. Port Finance seeks to be the liquidity gateway for the Solana DeFi ecosystem through simpler user interfaces, lower collateral requirements, and adjustable liquidation thresholds based on volatility and liquidity. Port’s native token will enable users to participate in governance and share in protocol fees derived from all protocol products. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
