The Trump family–backed USD1 stablecoin has had its official launch on JustLend DAO and now continues to build out its rapid integration across DeFi.
The official announcement stated JustLend DAO added USD1 as collateral on August 19th, 2025, allowing its users to lend, borrow and yield farm USD1.
USD1 is issued by World Liberty Financial Inc. (WLFI). It is fully backed by U.S. dollar deposits and short-term government securities, with reserves securely custodied at BitGo Trust, a regulated custodian.
According to Defilama, the circulating supply of USD1 now exceeds $2 billion, with USD1 quickly becoming one of the most liquid and adopted stablecoins in the marketplace.
Market Parameters and Interest Model for USD1 on JustLend’
The inclusion of USD1 into JustLend DAO includes carefully developed market parameters that facilitate risk and liquidity balance.
The collateral factor of USD1 has been set at a 0% collateral factor, so it may not be used directly as collateral for borrowing, while the reserve factor is 10%.
The protocol uses a jump interest rate model, in which borrowing costs increase at a gradual rate until utilization reaches 80%.
Once utilization exceeds 80%, the interest rates jump sharply to create a strong incentive to provide liquidity and to prevent an imbalance in market mechanics.
For example, the borrow APY rate jumps 6% on 80% utilization to 43.5% on 90% utilization with a related supply APY of 35.24%.
Rates at full utilization jump up to 81% and 72.9% respectively, illustrating JustLend’s method to balance risk in periods of high demand.
Strengthening JustLend and the TRON Ecosystem
The recent change enhances JustLend DAO’s position as a key lending hub within the TRON ecosystem.
By adding USD1, JustLend gives users a stable and high-liquidity asset option, which breaks the platform’s asset and yield turf.
It widens user options as a new asset, providing liquidity to the TRON DeFi ecosystem, and helps drive overall growth and maturity.
The proposal to add USD1 was submitted to community governance, reinforcing JustLend’s commitment to decentralized decision-making, and was transparent about market expansion.

Previous Milestones Show USD1’s Rapid Rise
The formal listing on JustLend is a continuation of a number of major events and milestones that accelerated the adoption of USD1.
On June 11, 2025, UnoCrypto reported that USD1 was the official dollar asset for MGX’s $2 billion investment in Binance.
The partnership cements USD1’s emergence as a legitimate dollar asset for the most significant institutional transactions.
U.S. Treasuries also back the stablecoin; USD1’s transparency and regulatory safeguards were key to securing that deal.
More recently, on August 7th, we also reported that USD1 launched a loyalty program with leading exchanges such as Bitget, HTX, and Gate.io.
The various loyalty programs aim to reward users with points for holding, staking, trading, and using USD1 in DeFi applications.
Also, they get points for enhancing the utility of USD1. All these gear towards encouraging long-term adoption by retail and institutional holders.
