The Problem
Solana DeFi historically lacked a robust, transparent, on-chain money market with isolated risk parameters per asset — early Solana lenders mixed risk pools and accumulated bad debt during volatile events.
The Solution
marginfi rebuilt Aave V2-style pool-based lending for Solana, adding per-bank isolated/reduce-only/paused operational states, dual Pyth+Switchboard oracle paths, and a configurable two-piece interest rate curve per asset.
Why it Matters
First major Solana lending market with isolated-bank risk parameters and a points-program go-to-market; complemented by a zero-fee liquid staking product (LST) and a permissionless leveraged-trading layer (The Arena).
