USDJ is a stablecoin that is pegged to the US dollar and backed by collateral assets. It is generated through decentralized smart contracts on the TRON network. The process involves pledging TRX as collateral to generate USDJ. USDJ is designed to play a role in the TRON DeFi ecosystem. It is part of the JUST DeFi ecosystem on Tron, which consists of JustStable and the JustLend DAO. The development of USDJ is overseen by the JUST Foundation, a team with experience from renowned tech companies.

To generate USDJ, one must deposit collateral assets into Collateralized Debt Positions (CDP) as part of the process. Users first convert TRX to PTRX. To generate USDJ, users carry out a transaction to JUST and create a CDP. Then execute another transaction in order to deposit PTRX, the collateral asset into that same CDP. When a CDP holder sends a transaction to create USDJ, the same amount of debt is also generated and collateral assets are locked up until repayment. USDJ also has a price stability mechanism in place. USDJ is initially pegged 1-to-1 to the US dollar. In times of market instability, a Target Rate Feedback Mechanism (TRFM) will be deployed to keep its denomination constant.

USDJ was developed with the intention of contributing to the DeFi ecosystem on TRON. As a stablecoin, it aims to provide stability in the often volatile cryptocurrency market. It can be used in a variety of DeFi applications, including lending platforms and decentralized exchanges. USDJ also has a global settlement mechanism that can be initiated by JST token holders to mitigate potential risks and damages. This mechanism, along with the risk-management program, makes USDJ aim to be a stable asset in the DeFi space.

USDJ is a product of the JUST network ecosystem, developed by the JUST Foundation. The JUST Foundation is a team with experience from renowned tech companies like Alibaba, Tencent, and IBM. The vision behind USDJ was to create a stablecoin that could contribute to the DeFi ecosystem on TRON. USDJ is a TRC-20 token issued on the Tron blockchain, which utilizes a delegated-proof-of-stake (DPoS) consensus mechanism. USDJ has a circulating supply.
