Of course! If your friend opens the link they've been sent after the payment has been cancelled, they can still select “Explore Curve”. From there, they can download the Curve app and begin creating their account.
You’ll both receive the referral bonus after they’ve made their first transaction using Curve. Just make sure they make their first transaction within 7 days of entering the code to receive the signup bonus (applies from June 22nd, 2020)!
If your friend or family member hasn’t accepted your Curve Send transaction and signed up for the account within 7 days, your payment will be reversed back to your underlying payment card and the pending status will be lifted from the transaction.
