A wallet is a digital place where you can store cryptocurrency coins and tokens. A wallet address is a randomly generated combination of digits and letters that is associated with a particular wallet. MASMINT does not provide wallet addresses and never stores user deposits. To exchange cryptocurrencies on MASMINT, you need to provide an. existing wallet address where you can receive your exchanged currency.

Just figure out what coin you want to buy and look for a stable compatible wallet. As a rule, each coin has its official wallet client.

Note that each wallet has its unique address or a tag with a private key that is required to restore your wallet if you lose it. MASMINT will never asks for your private keys. Store them in a safe place and never show them to anyone. If your private keys are stolen, your wallet and all your coins will be lost How do I get a wallet address?

In any transaction there is always a sender and a recipient. The recipient’s address is the wallet address where you will receive the currency you buy. For example, if you want to buy Ether (ETH), you should specify an ETH wallet address in the recipient field, and MASMINT will send coins to this address once the transaction is complete.

In general, the recipient’s wallet address is a customer's address MASMINT will send coins to once a transaction is complete.

All wallet addresses provided by MASMINT are reusable and tied to your recipient address. You can send multiple amount of coins to the address generated earlier without creating a new transaction on MASMINT. In this case, your coins sent will be automatically exchanged to the same currency and sent to the same wallet address.

A hash (or tx ID) is the unique address of a transaction in a blockchain that acts as a record or proof that the transaction has taken place. Usually, the hash is a combination of digits and lowercase letters. Whenever you make a payment in cryptocurrency, you receive a hash displayed in your wallet. Every hash should be located in a blockchain. If you have any issues with a transaction on our platform, our support team may ask you to provide the hash for the transaction in order to find your payment and resolve the issue.

MASMINT does not have set amount restrictions. However, there are some cases when a minimum amount applies:

If an amount is very low, make sure that it will cover all costs required by a blockchain. This means that the amount you are going to send and the amount you are going to receive should be enough to cover input and output network fees taken by a blockchain.

Each time any amount of cryptocurrency is sent or exchanged, the currency goes through a blockchain. This process requires a small fee called a ‘network fee’. The network fee is a commission that a blockchain takes from the amount sent in each currency. It is critical to make sure that the amount you want to exchange on MASMINT is enough to cover the exchange fees for both the process of sending your original currency and receiving the new currency you want to buy. If the sent amount is too low to cover the fees of the network, the transaction will not go through and your funds will be lost.

 All transactions take time to be processed (usually 5-30 minutes). Given the volatility of cryptocurrencies, the exchange rate is subject to change during the processing time, which means the final rate may be slightly different from what you expected.

Unfortunately, blockchain transactions are irreversible. Once a transaction is made (money is sent to a particular wallet address), it cannot be rolled back. So, if you are going to exchange cryptocurrency, be sure to double check all payment details carefully before sending.

It your transaction takes longer, this could be due to a variety of factors, including:

  • Blockchain overload. There are many transactions waiting to go through, including yours. This issue occurs on the Bitcoin and Bitcoin-based blockchains. Unfortunately, the only thing to do is wait. MASMINT has no control over a blockchain overload.
  • Coin updates. We may turn off some coins to update a client. This can take some time. You will get your money as soon as we turn it back on.
  • DDoS attacks. Every platform is subject to such attacks. Unfortunately, in this case the only thing to do is wait it out.

There are several reasons this might be happening:

  1. The transaction has not been included in a block. Cryptocurrencies are not stable, so minor errors sometimes do occur. If this happens we will either refund you your money or push the payment through if you can provide the hash (a tx ID) of your transaction.
  2. ETC and ETH confusion. The addresses of Ethereum (ETH) and Ethereum Classic (ETC) have the same structure. If you send ETC or ETH, make sure that you have selected the appropriate transaction type on MASMINT. For example, if you create an ETH to BTC transaction, make sure that you send ETH, not ETC. Otherwise your transaction will get stuck
