🔰Multi-collateral system

How Does Multi-collateral System Work?

JOJO uses USDC as the settlement currency, but you can also use other assets as collateral. Specifically, this is a credit issuance system similar to DAI, where you can borrow out JUSD by over-collateralizing assets such as ETH. And JUSD is considered to have equal value to USDC within JOJO's perpetual contract trading system.

Although you trade using JUSD, profits and losses are still settled in USDC. This means that if you make money, you can withdraw it in USDC. If you lose money, your JUSD will be locked until you repay the debt with USDC.

You can buy and sell JUSD on the secondary market just like you trade DAI. However, no matter what the price of JUSD is on the secondary market, within JOJO's trading system, 1 JUSD will always be equivalent to 1 USDC.

Liquidation

When the value of your collateral decreases, you will face liquidation.

Initial ratio: If the value of your collateral multiplied by its corresponding initial ratio is less than the JUSD you have borrowed, you will not be able to borrow more JUSD.

Liquidation ratio: If the value of your collateral multiplied by its corresponding initial ratio is less than the JUSD you have borrowed, you will be liquidated.

JOJO's initial ratio and liquidation ratio are formulated based on JOJO's predictions on the price fluctuations of non-stable tokens and the platform's ability to pay. The price of non-stable tokens is provided in real-time by Chainlink.

The liquidation occurs on-chain and is open to anyone without the need for permission. The system will sell collateral at a discounted price for USDC.

It's important to note that the liquidation process for the multi-collateral system operates independently of the perpetual futures trading system. Therefore, while your multi-collateral assets may be subject to liquidation, your futures positions will remain unaffected.

JUSD Floating Rate

Maintaining a secure platform is our top priority and JUSD uses a special floating exchange rate to achieve that. This system adjusts automatically in response to redemption pressure, ensuring the overall stability of JUSD

Definition

  • USDC debt = The sum of the maximum amount of USDC that all users can withdraw (exclude insurance fund)

  • USDC inventory = The amount of USDC in the Dealer Contract

  • USDC redemption pressure = USDC debt / USDC inventory - 1

JUSD interest rate curve simulation

  • If redemption pressure ≤10%, interest rate = 0%

  • If 10% < redemption pressure ≤25%, interest rate = redemption pressure

  • If redemption pressure >25%, interest rate = redemption pressure * 2

The backend is actively triggered and adjusted once a week. If the JUSD interest rate changes by more than 5%, it will be adjusted immediately.

The interest generated by JUSD will be used entirely for the insurance fund.

JUSD Borrow Limitation

Regardless of collateral amount, the borrowing limitation is capped at 100,000.00 JUSD for each user. And the platform borrowing limitation is capped at 1,000,000 JUSD

JUSD for dedicated market maker

For dedicated market makers who have completed KYC, JOJO also supports the use of funds from centralized exchanges as collateral to mint JUSD on JOJO to help provide liquidity. If you want to become a dedicated market maker, please contact jotaro@jojo.exchange.
