Build chain-agnostic applications in minutes, not months.
The Universal Accounts SDK allows you to integrate Universal Accounts into your dApp, allowing you to onboard users from any ecosystem without requiring them to bridge—regardless of where your dApp is deployed.

What are Universal Accounts?

New to Universal Accounts? Understand the core concepts behind chain abstraction.

​
What You’ll Learn

In this hands-on mini course, you’ll build a complete Chain Abstracted application using the Universal Accounts SDK. By the end, you’ll understand how to:
  • Create chain agnostic applications— users from multiple chains can interact with your dApp without the need to bridge
  • Abstract away chain-specific complexity from your dApps
  • Provide seamless user experiences regardless of blockchain choice
