marginfi is a decentralized borrowing and lending protocol built on the Solana blockchain by mrgn labs. Users lend supported Solana tokens to earn yield and borrow against supplied collateral, with account-health, e-mode, liquid staking token (LST), and leveraged looping (mrgnloop) products layered on top of the core mrgnlend market. marginfi exposes no hosted REST API — developers integrate on-chain through the marginfi-v2 Solana program using the official TypeScript SDK (marginfi-client-v2, mrgn-common) and the Rust (CLI) SDK, with an early-alpha Python SDK (marginpy) and a Rust CPI interface crate also published. It was surfaced through the API Evangelist network as a portfolio company of Multicoin Capital and Pantera Capital.
