A blockchain address is similar to an email address or a bank account number: it is used to receive and send funds on the blockchain network (like you use your email address to send and receive messages) and represents a destination for a cryptocurrency payment.
Each blockchain address contains a string of alphanumeric characters, but can also be shown as a scannable QR code. These addresses may have specific identifiers depending on the type of cryptocurrency. All bitcoin addresses, for example, begin with either 1 or 3.
You can find your Smartee blockchain address when viewing your cryptocurrency account details in the Smartee app.
