Just vs Variational

JustLend is Tron’s native money‑market where interest rates follow a jump‑rate model similar to Compound V2. The protocol supports TRX, USDT, USDD and SUN, and integrates with SunSwap for automatic collateral liquidation. Since 2021 the JustLend DAO has funnelled 30 % of reserve factor income into a community insurance fund holding 500 million USDD.
