1. Why can’t my wallet be connected and the liquidity added cannot be confirmed?
In the case that your wallet cannot be successfully connected, you are advised to check whether you have switched the main network. Since MDEX’s listing on BSC, the transaction volume increases sharply. It can be improved by increasing the gas limit.
2. Why did my swap fail?
It is possible that the node is delayed, causing the error in the acquisition price, or the price fluctuation is significant, causing an error between the current quantity and the quantity when the swap application is submitted. There may also be an optimal path, but the user has already submitted it.

4. Faster bsc nodes in China
1). If your transaction is under confirmation (Pending), please increase your Gas fee (now the average Gas fee has reached Gwei 9–10). You can refer to the fee charged latest transaction as a reference for the Gas fee to be paid. Website: https://bscscan.com/txsPending?&m=&p=6
2). If you cannot send the transaction (you can’t see any transaction confirmed), please change your RPC settings and initiate the transaction again. Currently online stable RPC nodes can be viewed through https://bscproject.org/#/rpcserver
Node replacement can be selected in the following link:
5. Other issues related to approve failure, withdraw failure, etc
You can try to increase the gas fee or try to switch nodes.
To switch Metamask nodes: setting — network — original BSC main network — RPC. To complete the process on mobile ends: settings-node settings
6. Free transaction fee
In essence, the reward of transaction mining is a subsidy to users who have transaction needs. Compared to other decentralized exchanges that charge 3% transaction fees, transactions on mdex are almost for free.
Transaction fees generated in trading token pairs will be directly reserved in the corresponding LP pools. Only when you create or withdraw liquidity will the transaction fee will be injected to the smart contract in the form of LP.
7. Why is the HMDX supply on the BSC chain 1 billion? Seen through the contract address.
HMDX is a cross-chain token of MDX issued on BSC. It corresponds to the MDX on HECO. The volume of HMDX is equal to the MDX locked in the contract. After HMDX migrate back o HECO, it will be burned and the same amount of MDX on HECO will be unlocked. The total amount of HMDX is the same as the MDX on HECO, but as MDX output reduces ahead of the schedule, the total amount of MDX on HECO is no more than 700 million.
8. What isn’t the swap rate 1:1 between hmdx and mdx?
MDEX needs to maintain the same output mechanism on HECO and BSC (80 MDX per block), which means that it needs BSC native tokens. The cross-chain token HMDX on BSC belongs to users and cannot be used to reward miners. And there is still a gap between the amount of HMDX and the amount of MDX mined on BSC, which leads to a price difference when users buy and sell tokens. But as the circulation of HMDX on BSC increases, the price difference is narrowing down. HMDX will become MDX when it comes back to HECO.
9. Is MDX on BSC and MDX on heco the same token?
The MDX on the BSC is part of the 1 billion MDX output. Since the mdx output on the BSC in the early stage is small, its price on BSC differ from HECO. We will try our best to adjust the price difference through the Boardroom, repurchases, rewards, and the proportion of future output, etc., to achieve the goal of 1:1 swap rate.
10. Does MDEX plan to introduce NFT and contracts?
MDEX probably will introduce them in the future to enrich the ecology but it needs to be done step by step. If there is any adjustment or enhancement of the operation strategy, we will announce it through official channels as soon as possible. Stay tuned with our official account.
11. For the same LP, why do the LPs of the Boardroom and of the mining pool have different rates of return?
The liquidity mining pool rewards users by blocks, while the Boardroom LP gives transaction fee rewards. The sources of the rewards are different.
12. What is the repurchase mechanism after listing on BSC?
MDEX will inject the corresponding proportion of daily platform income into the fund pool for repurchase. When the repurchase price (72-hour MDX average price) is triggered, the smart contract will automatically execute the repurchase and burn it. Otherwise, it will continue to accumulate in the repurchase pool. Note: When repurchasing from the secondary market, HMDX or MDX with a lower price will be preferred for the repurchase-burning.
13. Why does MDEX adjust the repurchase speed from 9 seconds to 90 seconds?
Due to the recent congestion of the BSC network, MDEX adjusts the repurchase time and gas fee setting, and optimize the repurchase-burning scheme to increase the success rate of MDEX repurchase in the Boardroom. None of these changes will affect the total amount of MDEX for repurchase and burning. The contract will continue to repurchase and burn according to the amount of MDEX in the repurchase pool.
14. Why does the address 0x2f7ac9436ba4b548f9582af91ca1ef02cd2f1f03 have 900 million hmdx?
About the cross-chain and contract address of MDEX
1). Since the initial issuance, HMDX has been directly transferred to the cross-chain lock-up agent contract address. Users can check the token issuance and lock-up status through the following address:
HMDX token contract address:
Lock-up agent contract address:
2). About MDX cross-chain mechanism
When the MDX on HECO network is transferred to the LOCK contract and the lock is confirmed, the same amount of HMDX will be unlocked from the lock-up agent contract;
When the HMDX on BSC is transferred to the lock-up agent contract, the LOCK contract of the HECO network will be triggered to unlock the same amount of MDX. Users can view the LOCK contract on HECO through the following address:
15. Delays in receiving assets through the bridge
If the delay occurs, please try to change the node and check whether the wallet link is normal. And if the delay persist, please contact the MDEX team and provide the transaction hash to view the cause of the delay.
16. Is the annual MDX APY compounded?
No, the APY displayed on MDEX website has single interest.
17. Problems related to incorrect MDX APY in the Boardroom (caused by not adding mining pool rewards)
MDX purchases MDX in the secondary market and distributes the tokens through the Boardroom. Therefore, the calculation of APY should be in real time, so there will be a price difference between the APY in display and the actual APY.
18.MDX wrongly sent to the contract address
All the tokens that were mistakenly transferred to the contract address cannot be recovered by the MDEX team. The contract does not allow any asset withdrawal.
19. The MDX on BSC is significantly less than on HECO but still cheaper?
Since the circulation of MDX is produced by mining, MDEX does not reserve tokens, and therefore cannot be swapped in a short time. We will adjust the amount of MDX in the Boardroom reward pool, the repurchase mechanism, and the way tokens are produced on different chains in the future. In this way, we aim to balance the swap rate of tokens on the two chains close to 1:1. At present, MDX is used on HECO and BSC, and the APY is quite different. Please invest your assets according to the risk preference.
20. Why is MDX suspended on BSC when it reaches the average price?
This is related to the insufficient repurchase amount. Specifically, only when a certain amount of repurchase assets is accumulated will it trigger the smart contract to start the burning. Since the amount to be repurchased depends on the system’s regular transfer into the contract, when the current repurchase intensity is greater than the asset transfer frequence, the repurchase will be suspended. As funds are accumulating in the pool, such problem will be gradually solved.
