JustLend DAO has launched Supply and Borrow Market V2, introducing an isolated lending framework and a new Adaptive Curve Interest Rate Model designed to improve capital efficiency and risk controls across its decentralized lending platform. According to the protocol's announcement on June 17, the upgrade replaces the previous structure with a dual-layer system built around Treasury and Markets, with the release taking effect on June 17 Singapore time. The new design allows users to deposit a single asset such as USDT into a Vault, which acts as a central liquidity pool and distributes funds across multiple lending markets, with depositors earning returns generated from all connected markets.
The upgrade introduces an Adaptive Curve Interest Rate Model, an updated version of the Jump Curve model previously used in Supply and Borrow Market V1. As reported by JustLend DAO, borrow rates no longer rely solely on a fixed utilization threshold, with the entire rate curve moving up or down depending on market conditions. When utilization remains below target levels, borrowing costs decrease to encourage loan demand, while during periods of elevated utilization, rates rise to promote repayments and improve liquidity availability. The mechanism is designed to keep utilization closer to target levels while maintaining stable borrowing conditions across markets, encouraging liquidity management and stable borrowing conditions.
The new version introduces isolated market operations where each market maintains its own lending parameters, including loan-to-value settings. According to JustLend DAO, this setup prevents problems in one collateral market from affecting others and reduces the possibility of contagion spreading across the protocol. Under the new design, borrowers interact directly with individual Markets by pledging approved collateral assets and borrowing funds against them, with each Market operating independently to limit system-wide risk exposure. The Treasury aggregates liquidity while each Market supports independent lending and bears its own risk exposure, achieving complete risk isolation across the protocol. This innovative independent collateralized lending protocol significantly enhances the protocol's risk management capabilities and capital efficiency, further strengthening security and flexibility in independent multi-asset lending scenarios.
The upgrade comes as JustLend continues expanding activity across the TRON ecosystem while pursuing a revenue-backed token burn strategy for JST. According to the protocol's April disclosure, JustLend DAO completed its third JST buyback and burn, permanently removing 271.3 million JST worth approximately $21.3 million from circulation. The purchase was funded through first-quarter 2026 net income together with previously accumulated profits. That transaction pushed cumulative JST burns to more than 1.35 billion tokens, equal to 13.70% of the total supply. These changes aim to enhance security, efficiency, and liquidity distribution across the decentralized lending platform while supporting growth on the TRON ecosystem.
