Buy and Sell with Ease with Cash App on Bitkey
As the product designer on Cash App, I partnered with the Bitkey team to enable Bitkey customers to seamlessly buy and sell Bitcoin directly through Cash App. I collaborated with product, engineering, and data teams to design a streamlined, user-friendly experience that bridges the two platforms, ensuring customers could securely manage their Bitcoin transactions with ease.

Problem & Opportunity
Bitkey gives the customer options for which provider they want to use to buy and sell their bitcoin. While this is great on the one hand, this brought challenges in differing fee structures across Bitkey and partner apps. Cash App was a hero use case in bringing clarity and understanding.

Problem & Opportunity
While the Lightning network can provide tremendous value of instant and free payments, the nature of Lightning invoices can be difficult to grasp for the every day Cash App customer.
Our goal was to remove the complexity and make it "just work".
The invoice
Most Lightning network invoices require an amount before being shared. We wanted to give the optionality to users by upping the expiration time.
This would simply allow someone to share a QR code or link for payment - the amount up to the payer.
Adding an amount for the payer through scanning or pay by link.

Paying via link
While not the norm, simply sharing a QR or link without an amount works just as well.
Optionality
By bending the rules of invoice expiration, the requester can choose to add an amount or simply let the payer choose the amount.
