The Collaborative OS for Web3

Cardstack opens the doors to Web3 for everyday people.
Building software is no longer reserved for experienced developers.
NFTs, DeFi and blockchain are no longer reserved for the crypto-savvy.
Instead, anyone will finally be able to build apps, create content and get paid in decentralized ways—no coding or crypto experience required.
Let’s break down the barriers that limit what we can achieve together.

We are launching the product suite in stages. The first one to launch is our payment protocol Card Pay and its companion app Card Wallet, which is currently in beta.
