At the lower middle area of “Invite” page, there is a 6 letters referral code which is unique for each user. You can click on the referral code to copy and send to your friends. To successfully receive your invitation rewards, your friends will need to correctly enter your referral code while registering his or her SwapAll account. Alternatively, you can click 【post】to generate an invite poster as an image. Share the invite poster to your friends so they can scan the QR code to register with your referral code automatically.
