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 U market opened with specific lending parameters designed to manage risk exposure. As reported by JustLend DAO, the market launched 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, where borrowing costs rise sharply once utilization exceeds 80%.
JustLend DAO's published parameters show the interest rate trajectory for both borrowing and supply activities. According to the protocol, 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 pattern, rising from 3.6% at 80% utilization to 34.43% at 90% utilization and 72% when utilization reaches 100%. The U listing arrives days after JustLend DAO introduced Supply and Borrow Market V2, a lending framework that took effect on June 17.
The U listing arrives within JustLend DAO's updated architecture framework. As reported by the protocol, the June 17 upgrade introduced Supply and Borrow Market V2, which operates on a lending framework where depositors place assets into Vaults that distribute liquidity across multiple lending markets. Borrowers interact with individual Markets that operate independently, with the design isolating risk between collateral markets and limiting the impact of problems that may arise within a single asset pool. 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.
