Funds transfer works as follows: a specified cryptocurrency is transferred from one account to another using an address and network number or a QR code. It's essentially like a bank transfer - you just need a balance and a bank account number.
To make a token transaction from one exchange to another, you need to know the blockchain address of the recipient wallet/account. This data is generated on the recipient’s exchange/wallet.
Also, when transferring funds, you need to correctly specify the address of the token you are going to transfer to the new account. Each cryptocurrency has its own address on the blockchain sub-account. On cryptocurrency exchanges, Bitcoin is stored in one sub-account, Ethereum in another, and USDT in a third. But the trader sees all the sub-accounts combined into a common account.
Remember that blockchain transactions cannot be undone, so you should triple-check all the details before making the transfer.
