  1. Wallet selection: The application will offer different wallet options, such as MetaMask, Trust Wallet, Ledger and others.
  2. Authentication: Enter or scan the QR code that is displayed in the application using your cryptocurrency wallet.
  3. Access Permission: Confirm the permissions the application requests to access your assets.

How to send tokens to the exchange and use the MEMO field

Sending tokens to the exchange
When you submit tokens to an exchange, the process typically includes the following steps:

  1. Get the deposit address: On the exchange, find the “Deposit” section and select the token you want to send. You will be provided with a deposit address for the specified token.
  2. Copy the address: Copy the deposit address and, if required, the MEMO.
  3. Open your wallet: In your wallet, select the "Send" option.
  4. Paste the deposit address and amount: Paste the copied deposit address into the Recipient field and enter the amount you want to send.
  5. Specify MEMO if required: Some tokens (for example, Stellar, EOS, etc.) require an additional MEMO field (or tag). MEMO is used to identify your deposit on the exchange's general account.
  6. Confirm the transaction: Confirm and submit the transaction. Make sure all details are entered correctly.
    MEMO field (or tag)

The MEMO field is an optional field that is used by some cryptocurrencies to ensure the correct routing and identification of the transaction on the recipient side.

  • What is it used for: MEMO is needed for various tokens that use one common account for all users. It helps the exchange correctly match the incoming transaction to your account.
  • When required: The MEMO field may be required to send tokens such as Stellar (XLM), Ripple (XRP), EOS, and others. If you do not specify MEMO, your tokens may be lost or funds may be delayed in your account.

As a result, properly understanding the process of connecting a wallet to an application, the differences between wallets, and the specifics of sending tokens to an exchange is important for the safe and efficient management of cryptocurrency assets.
