The June 17 upgrade shifts JustLend from shared pools to isolated collateral markets and adds an adaptive interest rate curve aimed at limiting contagion risk and improving capital efficiency.
JustLend DAO on June 17 launched Supply and Borrow Market V2, moving its TRON-based lending protocol from shared pools to an isolated collateral structure and replacing its prior jump rate model with an adaptive interest rate curve. Under the new design, depositors place assets such as USDT into shared vaults that route liquidity across separate borrowing markets, each with its own collateral and risk settings. That means a collateral failure in one market is intended to trigger liquidations only there rather than spreading losses across the protocol. The upgrade also introduces market-specific risk parameters, including Liquidation Loan to Value Ratio, or LLTV, while keeping the protocol’s Chainlink oracle system and governance through JustLend Improvement Proposals overseen by JUST token holders. The redesign reflects a broader DeFi lending shift toward isolated market structures seen in platforms such as Euler V2 and, in part, Aave’s isolation mode, as protocols seek to reduce systemic risk and make deposit capital more efficiently deployable.
