JustLend DAO has launched Supply and Borrow Market V2, introducing an isolated lending framework and new interest model designed to improve capital efficiency and risk management within the decentralized lending platform.
According to JustLend DAO’s announcement on June 17, the upgraded protocol replaces the previous structure with a dual-tier system built around Vaults and Markets. The release, which came into effect in Singapore on June 17, is part of the platform’s latest effort to improve the way liquidity is distributed while limiting the impact of risks associated with individual collateral assets.

Under the new design, users can deposit a single asset, such as USDT, into a vault, which acts as a central liquidity pool and distributes funds across multiple credit markets. Depositors earn returns from all connected markets, with interest automatically aggregated through the Vault structure.
Borrowers, meanwhile, interact directly with individual markets by pledging approved collateral assets and borrowing money against them. Each market operates independently, a setup that JustLend DAO says prevents issues in one collateral market from affecting others and reduces the possibility of contagion spreading across the protocol.
New interest model introduced
In addition to the architectural changes, JustLend DAO has rolled out an Adaptive Curve Interest Rate Model, an updated version of the Jump Curve model previously used in Supply and Borrow Market V1.
The protocol explained that interest rates are no longer solely dependent on a fixed usage threshold. Instead, the entire yield curve can move up or down depending on market conditions. When usage remains below target levels, financing costs drop to stimulate loan demand. During periods of increased utilization, interest rates increase to promote repayments and improve liquidity availability.
According to the announcement, the mechanism is designed to keep utilization closer to target levels while maintaining stable lending conditions in the markets.
The risk control measures will also receive a substantial update in the new version. JustLend DAO said each market now maintains its own lending parameters, including loan-to-value settings, allowing liquidation events or drops in collateral prices to remain isolated within a single market rather than impacting the entire lending system.
JustLend DAO added that the latest changes are intended to provide a more efficient and secure lending experience while supporting continued growth in the platform’s decentralized finance ecosystem.
The upgrade comes as JustLend continues to expand operations in the TRON ecosystem while pursuing a revenue-supported token burn strategy for $JST.
Earlier this year, JustLend DAO completed its third $JST buyback and burn, permanently disposing of 271.3 million $JST worth approximately $21.3 million from circulation. According to the April disclosure of the protocol, the purchase was financed from the net revenues of the first quarter of 2026, together with previously accrued profits.
That transaction created cumulative $JST burns to over 1.35 billion tokens, equal to 13.70% of the total supply.
