With ForTube Bank, users are able to earn interests by depositing their digital assets in the smart contract. Meanwhile, they will obtain loan quotas, and are allowed to lend an amount of their cryptocurrency that is within the quota. Users no longer need to pay attention to the duration and can withdraw or pay anytime, regardless of whether it is a deposit or a loan.

When the borrower's outstanding loan exceeds the limited ratio of its collateral, the system will seize the user's assets and start the liquidation process. Now, arbitrageurs are allowed to call the liquidation contract and replace the seized assets at a certain discount. Since various digital assets differ in market size, liquidity, price stability, etc., their collateral rates, liquidation discounts, etc. will not be the same. Please check the following table for product information.
