What Is USDJ (USDJ)?

In the whitepaper, USDJ is described as a USD-pegged stablecoin backed by collateral assets, generated through decentralized smart contracts on the TRON network. "Anyone can pledge TRX as collateral to generate USDJ." It is reportedly pegged to the US dollar through Collateralized Debt Positions (CDPs), and has autonomous feedback mechanisms. The vision behind USDJ is to make it an integral piece of the DeFi ecosystem on TRON.

USDJ is part of the JUST DeFi ecosystem on Tron, which consists of JustStable and the JustLend DAO.

Who Are the Founders of USDJ?

USDJ is a product of the JUST network ecosystem. It is developed by the JUST Foundation, which consists of a vibrant and talented team with experience from Alibaba, Tencent and IBM.

How Does USDJ Work?

As laid out in its whitepaper, 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. Thereby, making that particular asset unavailable for redemption.

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.

What Makes USDJ Unique?

When the USDJ price received from Oracles is different from the real US Dollar rate, JST token holders can initiate a global settlement mechanism to mitigate any potential risks and damages; this process comes in three steps:

First, the global settlement mechanism is activated after which CDP holders are unable to create or modify their positions. Meanwhile, the price feed will be preserved at a fixed value in order to process all users' claims accurately and promptly.

Second, keepers in the JUST system will use a price feed to auction off all debt and collateral assets in a decentralized manner, thus granting settlement for USDJ and CDP holders' claims.

Subsequently, to Keepers handling Global Settlement claims, all USDJ and CDP holders can file a claim petition on JUST in order to exchange their USDJ or CDPs for an unchanging quantity of TRX depending upon the Target Price of USDJ. There is no deadline set as far as when users must take this step.

The USDJ stablecoin system is also equipped with a comprehensive risk-management program. JST holders who are part of the JUST governance system fully control the key decisions to regulate risks in the entire ecosystem. These steps include modification of sensitivity parameters through the Target Rate Feedback Mechanism (TRFM), modification of Target Rate, choosing trusted oracles, and other security mechanisms outlined in the official whitepaper.
