What we like
JustStable is one of the largest borrowing protocols that enables loans paid out in its own USDJ stablecoin, which is overcollateralized by TRX.
What we like less
The platform only accepts TRX as collateral to back USDJ, which can impact its peg stability as TRX is a highly volatile asset.
What it means for you
Offers you a simple way to borrow a decentralized stablecoin and put it to use to earn yield for you across DeFi apps on the Tron network.

Things to know about JustStable

How JustStable works

JustStable is a decentralized borrowing protocol that allows borrowers to draw loans against TRX deposits. Loans are paid out in USDJ, a USD pegged stablecoin with a collateralization ratio of at least 130%. The DAI peg is further supported by a Target Rate Feedback Mechanism (TRFM). The TRFM triggers once the price of USDJ falls below the Target Price (1 USD) and will increase the Target Rate, thus making it more expensive to mint USDJ with TRX. The increased Target Rate also drives up the demand for holding USDJ. As such, the reduced supply and increased demand works to drive up the price of USDJ back to its Target Price. And vice versa, the same mechanism works in reverse by decreasing the Target Rate when USDJ is above the Target Price.

How JustStable makes money

JustStable collects a stability fee on all USDJ generated through its smart contracts. The stability fee is a variable-rate fee that continuously accrues to the generated USDJ by a user but must be paid in JST governance token. Once repaid, the JST will be burned and removed from the circulating supply.

How you make money on JustStable

You can deposit TRX into the JustStable to mint USDJ to be used across DeFi on the Tron network.
