JustLend DAO has expanded its lending platform by supporting the supply and lending of U, a TRC-20 stablecoin pegged to the US dollar.
According to a June 21 announcement, users can now deposit and borrow directly on the protocol after the asset was added as a collateral market on June 20, 2026, Singapore time.
The launch follows a governance proposal that outlines the credit parameters and interest rate structure of the market.
Under protocol, U is issued by United Stables and maintains its linkage through reserves backed on a 1:1 basis. JustLend DAO described the asset as a stablecoin designed for digital trading, machine-to-machine payments and AI-focused financial applications on the TRON network.
U market introductions with separate credit parameters
JustLend DAO said the U market opened with a collateral factor of 0% and a reserve factor of 10%. The collateral factor means that users can lend to U on the platform, but cannot use U as collateral to obtain other loans at launch.
The protocol also introduced a spring rate model to the market. Under this structure, financing costs rise sharply once the occupancy rate exceeds 80%.
JustLend DAO’s published parameters show that the credit APY reaches 5% at 80% utilization before rising to 42.5% at 90% utilization and 80% at full utilization.
The supply APY follows a similar trajectory, rising from 3.6% at 80% occupancy to 34.43% at 90% occupancy and 72% when occupancy reaches 100%.

The U-listing arrives days after JustLend introduced DAO Supply and Borrow Market V2, a lending framework that went into effect on June 17.
Under the updated architecture, savers place assets in vaults that distribute liquidity across multiple credit markets, while borrowers interact with individual markets that operate independently. JustLend DAO said the design isolates risk between collateral markets and limits the impact of issues that could arise within a single asset pool.
The June 17 upgrade also introduced an Adaptive Curve Interest Rate Model. JustLend DAO said the mechanism adjusts financing costs based on market utilization rates, rather than relying solely on a fixed threshold.
Under the protocol, the community board retains authority over new market introductions, and the U-market was introduced through the proposal process before becoming available to users.
