1.1 connection problem

Q:"Unsupported network" or "Not connected to network" is displayed

A:First confirm whether it is connected to the Heco network, after connecting to the Heco main network, refresh the web page

Q: The deposit and loan market is not loaded, but the page layout is loaded successfully

A: Switch node-click on the upper right corner where the wallet address is displayed, click the node drop-down box, the upper part is the domestic node, and the lower part is the foreign node. After switching the node, refresh the page (it is recommended to select the window.ethereum node)

Q: The webpage reports an error and cannot be loaded

A: First check whether it is a network problem, and then confirm whether other Dapps can be accessed

2、Deposit/withdrawal issues:

Q: Where can I get the CAN token??

A: Click the [Claim] button in the upper right corner

Q: What do the following two figures of deposit income/borrowing cost of a single currency mean?

A: The former is the annual deposit interest rate/the annual interest rate of borrowing, and the income/expense is the currency of deposit/borrowing; the latter is the mining return rate, and the income is CAN currency. As shown in the figure below, the deposit is USDT. Among the 6.42% of the deposit income, 4.18% is the USDT local currency income, 2.23% is the CAN income of deposit mining, 6.42%=4.18%+2.23%. In the same way, the borrower is USDC. Of the 6.31% of the borrowing cost, 10.41% is USDC local currency interest, 4.10% is the CAN income of borrowed mining, 6.31%=10.41%-4.10%

Q: What is cToken?

A:The platform is used as a certificate to record the source of deposits. There is cToken indicating that there are deposits on the Channels platform. cToken can be used as a voucher with a check function to withdraw and deposit on the Channels platform. Unable to withdraw the corresponding Token from the platform

Q: What is the net profit?

A: net profit = deposit income (deposit interest + deposit mining income)-borrowing cost (borrowing interest-borrowing mining income) = net interest rate (deposit interest-borrowing interest) + mining income (deposit mining income + borrowing Mining income)

Q: What does the Collateral button do?

A: You can borrow money only after you deposit and open the mortgage. The higher the value of the collateralized tokens, the higher the amount that can be borrowed.

Q: Is the deposit income simple interest or compound interest?

A: Deposit income = deposit interest + deposit mining income, where deposit interest is compound interest and deposit mining income is simple interest

Q: How is the handling fee for deposit and withdrawal in can calculated (the deposit handling fee fluctuating law, percentage)?

A: CAN deposits and loans do not require handling fees. The fuel fee charged is HT charged by the Huobi platform, and the fuel fee is very low. The collection of fuel costs can be adjusted by itself, and there is no fixed rate.

Q: Is mining based on your deposit interest rate, or based on computer computing power? How much is the approximate deposit for digging 1 CAN in a day? (Economic model—mining income—mathematical formula)

A: Mining is calculated based on the deposit interest rate. The deposit interest rate fluctuates in real time. (Interest rate + 1) to the power of 365 is the daily interest rate

3. Single currency deposit and borrowing issues:

Q: What does it mean that the borrowing cost is negative?

A: Borrowing cost = Borrowing Interest-Borrowing mining income. When the borrowing mining income is higher than the borrowing interest, the borrowing cost is paid. In other words, borrowing money can still make money. For example, the borrowing cost of HBCH is -4.41%, which means that if you borrow 100 yuan, you will get 104.41 yuan after one year.

Q: I have already repaid the loan, why is there still a $0.02 loan?

A: During the time when the repayment was waiting for the transaction to be packaged, new borrowing interest happened to be generated again. This part of the newly generated interest was not included in the original principal and interest and can only be repaid again.

Q: Why is the transaction failure always prompted?

A: First check the node problem, then check whether the HT is used as the miner fee to pay successfully, and then confirm whether the operation is wrong (for example, manually input the loan amount is greater than the loan limit, and operate the withdrawal without releasing the mortgage). When the fuel cost is not enough, the transaction will fail. It is recommended to manually increase the gas limit or gas price

Q: Why was the cost of borrowing only 1% when I borrowed, but now it has become 15%?

A: The deposit and borrowing interest rate of the same currency changes in real time. When the number of borrowers increases, or the number of deposits decreases, the cost of borrowing will increase, and the deposit income will also increase.

Q: Why can't I borrow money?

A: To open a new wallet, you first need to have HT in the wallet; in addition, when you borrow, you must ensure that the mortgage is turned on when you deposit before you can borrow.

Q: How does the loan interest rate change? If it changes at any time, will the interest be charged in real time?

A: The lending interest rate changes in real time, and the interest is accumulated in blocks in real time into your loan, and it will be repaid together when you repay it.

4、LP-MDEX Problems:

Q: How to organize LP mortgage loans?

A: You can group LPs in the [Capital Pool] of Mdex. After success, you can directly open Channels and select the corresponding LP to deposit.

How to make LP- mdex problems, please check this doc >>> Channels-LP-mining guide


Q: Can I borrow from LP?

A: LP only can stake.

Q: How much is the LP cycle income?

A: The LP recurring income can generally reach 2~3 times the income of only deposits. Users can decide on their own currency and

The number of times, the more times the higher the profit. Because LP has not opened the lending business, the specific method of operation for LP dolls is to deposit LP, and repeatedly deposit single currency assets after mortgage to obtain recurring income.

At the time of the test, the deposit income of LP:ETH/USDT was 44.63%, and the deposit and borrowing interest rates of DAI were 32.53% and 20.02%, respectively. After depositing and pledged 0.0017ETH-USDT (value $0.2), 10 dolls deposit DAI, the results are as follows:

The total deposit is $1.0004, the total borrowing is $0.8037, and the net income is 18.82%. The loan amount occupies 95.62%, which is equivalent to depositing the principal of $0.2, and 94.14% is obtained after the doll.

(Note: For the same currency deposit and loan cycle, since the currency price is the same, the deposit and loan value fluctuates the same, so there is almost no liquidation risk)

5. Liquidation issues:

Regarding liquidation issues, please refer to the official liquidation documents



Q: How to judge the risk of being liquidated?

A: When the loaned funds reach the settlement line/borrowing limit, that is, when the fund utilization rate reaches 100%, it will be liquidated. You can check the fund utilization rate on the official website. The figure below shows that the fund utilization rate is 88.36%. When deposits and borrowings are both non-stable currencies, it is recommended that the fund utilization rate be controlled within 80%. When at least one of the deposits and borrowings is a stable currency, it is recommended that the fund utilization rate be controlled within 90% to reduce the risk of liquidation.

Q: How can I check whether I have been liquidated?

A: Currently, it is not possible to view the clearing record directly on Channels. When the fund utilization rate reaches 100%, liquidation will be triggered, and deposits and borrowings will decrease after liquidation. On the one hand, users can determine whether the number of coins deposited and borrowed has decreased, and whether the capital utilization rate has decreased; on the other hand, they can also check the transaction records of the wallet address to determine whether they have been liquidated, query URL: https://hecoinfo .com/

Q: What is the liquidation process?

A: When the liquidator (usually a robot or scientist) detects that the borrower has triggered the liquidation, it first initiates the liquidation by calling the contract to help the borrower repay 0%~50% of the total loan amount (the liquidator randomly chooses the ratio), and After deducting the deposits of the same value of the liquidated user, 8% of the liquidation amount will be taken as a liquidation fee (to be borne by the liquidated person).

After the liquidation is completed, the borrower's deposits and loans will be reduced, and the fund utilization rate will be reduced to less than 100%.

Q: How do I participate in the liquidation?

A: The clearing code is open source and available for inspection.

1. The liquidation can be initiated by calling the liquidateBorrow interface of the contract on the chain. The contract will automatically check whether it meets the liquidation conditions and complete the liquidation. You can interact with the contract interface through Remix. The cToken addresses of several mainstream currencies:

· cHT : 0x397c6D1723360CC1c317CdC9B2E926Ae29626Ff3

· cHUSD:0x9a57eAB16d371048c56cbE0c4D608096aEC5b405

· cETH: 0x01371C08E2AE6F78D42c9796FA20DDb245Df3885

· cHBTC: 0x8feFb583e077de36F68444a14E68172b01e27dD7

· cUSDT:0x3dA74C09ccb8faBa3153b7f6189dDA9d7F28156A

2. Enter the borrower's loan address, liquidation amount, and the cToken address of the mortgage token can be liquidated, as shown in the following figure:

Q: Why did not trigger the liquidation, but the deposit amount showed less?

A: The deposit amount is related to the currency price. A decline in the currency price will lead to a decline in the value of the asset, not necessarily being liquidated.

Q: Is liquidation an automatic liquidation?

A: It is not an automatic liquidation. Anyone can participate in the liquidation and get the liquidation fee. Because the liquidation robot can perform real-time monitoring, the liquidation robot is generally used to complete the liquidation.

Q: If I pledge USDT to lend out HUSD, will the sudden increase in the borrowing rate of HUSD increase my fund utilization rate? Will liquidation be affected by fluctuations in borrowing interest rates?

A: The fluctuation of the borrowing interest rate will affect the utilization rate of funds and thus affect the liquidation. When the fund utilization rate approaches 100%, a sudden increase in the borrowing interest rate may cause the fund utilization rate to reach 100% and be liquidated. It is recommended to keep the fund utilization rate below 90% and repay in time to avoid such risks.
