Cardstack is building a decentralized software ecosystem to compete with the Software-as-a-Service (SaaS) offerings of Silicon Valley. This ecosystem combines open-source development tools with a user-friendly environment, backed by smart-contract-based protocols.

In order to create a new software economy that runs on crypto payments, it is essential to find a better way to pay for software — transactions must be fast, easy, and cheap instead of slow, difficult, and expensive. That is what Card Pay is all about.

The Card Pay Protocol is a decentralized finance protocol with the idea of both individual control and group dispersion. Transactions are done on-chain, where we can pool the money together and distribute it proportionally to the different participants who have made contributions to the network.

In other words: The Card Pay network allows customers to buy products and services from merchants using prepaid cards, while contributors like issuers, suppliers, or developers receive a portion of the revenue.

“CARD Protocol is Customer Acceptance (CA) and Revenue Distribution (RD). By combining CA and RD, you get the acronym CARD.”
– Chris Tse, Cardstack Founder
