A wallet address is a unique combination of letters and numbers used to identify your balance for a specific currency. The address is used to specify to which wallet you wish to send funds to as well as an indication from whom funds are received. A wallet address is, therefore, similar to the account number of your bank account. If you or someone else wishes to transfer funds to your wallet, they will specify your wallet address which allows the system to match the funds being sent to your wallet.
ChainEX also offers you the ability to generate a QR code for your unique address which depositors can use to transfer funds to your wallet even faster.
