JustLend DAO adds U stablecoin lending market on TRON

JustLend DAO has expanded its lending platform by launching support for supply and borrowing of U, a TRC-20 stablecoin pegged to the U.S. dollar.

According to a June 21 announcement, users can now deposit and borrow U directly on the protocol after the asset was added as a collateralizable market on June 20, 2026, Singapore time.

The launch follows a governance proposal that outlined the market’s lending parameters and interest rate structure.

The protocol said U is issued by United Stables and maintains its peg through reserves backed on a 1:1 basis. JustLend DAO described the asset as a stablecoin designed for digital commerce, machine-to-machine payments, and AI-focused financial applications on the TRON network.

U market launches with separate lending parameters

JustLend DAO said the U market opened with a collateral factor of 0% and a reserve factor of 10%. The collateral factor means users can borrow U on the platform, but cannot use U itself as collateral to obtain other loans at launch.

The protocol also introduced a jumping interest rate model for the market. Under the structure, borrowing costs rise sharply once utilization exceeds 80%.

JustLend DAO’s published parameters show borrow APY reaches 5% at 80% utilization before climbing to 42.5% at 90% utilization and 80% at full utilization.

Supply APY follows a similar trajectory, rising from 3.6% at 80% utilization to 34.43% at 90% utilization and 72% when utilization reaches 100%.

In a statement on X, JustLend DAO said the addition of U expands the range of stablecoin assets available on the platform and provides users with another source of on-chain liquidity.

The U listing arrives days after JustLend DAO introduced Supply and Borrow Market V2, a lending framework that took effect on June 17.

Under the updated architecture, depositors place assets into Vaults that distribute liquidity across multiple lending 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 problems that may arise within a single asset pool.

The June 17 upgrade also introduced an Adaptive Curve Interest Rate Model. JustLend DAO said the mechanism adjusts borrowing costs based on market utilization levels rather than relying solely on a fixed threshold.

The protocol said community governance retains authority over new market launches, and the U market was introduced through the proposal process before becoming available to users.
