How to mint USDO on the ONUS App

Mint USDO is the deposit of stablecoins into the USDO Vault in order to generate the corresponding amount of USDO as specified in the smart contract.

According to the mechanism of USDO, you need to use BUSD to mint USDO. However, for user convenience, the ONUS application supports minting USDO with three different assets: BUSD, USDT, or VNDC.

Step 1: At the main screen, scroll down to the Features section and select “More”. Select USDO.

Step 2: Click on the type of asset you want to use to mint USDO: BUSD, USDT or VNDC.

Step 3: Enter the amount (eg, BUSD) you want to mint into USDO. The system will display the corresponding USDO amount.

Step 4: Press “Mint” and confirm to complete.

How to redeem USDO on the ONUS App

Redeem USDO is when you burn USDO and get back collateral stablecoin (BUSD) at USDO/BUSD exchange rate at the time of Redeem.

You can easily Redeem USDO directly on the ONUS app by following these steps:

Step 1: At the main screen, scroll down to the Features section and select “More”. Select USDO.

About USDO

USDO is a “Special Coin” built in the ONUS Chain ecosystem. USDO is not only stable and secure as a stablecoin, but also has the potential to increase in price based on the development of the ONUS Chain platform.

USDO Mechanism:

According to the special mechanism of USDO, to generate (mint) USDO, users need to lock BUSD to receive USDO at 1:1 exchange rate.


  • 1 USDO initially equals 1 BUSD, hence the user must exchange 1 BUSD in order to mint 1 USDO.
  • Similarly, if the price of USDO rises to n BUSD over time, users must use n BUSD to mint 1 USDO.
  • For example, when 1 USDO is equivalent to 5 BUSD, the user must exchange 5 BUSD to mint 1 USDO.

USDO Treasury:

Treasury is simply a warehouse where all assets that guarantee the amount of USDO in circulation are stored. The Treasury guarantees 100% of the value of each USDO in circulation.

The Treasury consists of:

  • The entire amount of BUSD used to mint USDO
  • 20% AMM transaction fee on MiaSwap which is continuously converted into BUSD and added to the Treasury.
  • 0.3% redeem fee every time a user burns USDO to receive BUSD.
  • 0.03% transaction fee from HeraSwap.

Furthermore, successful projects deploying on the ONUS Chain are incentivized to contribute a portion of their revenue to the Treasury in order to increase the value of the USDO.
