Overview

Welcome to the Alien dev portal. This guide helps you integrate verification and authentication into your applications using the Alien ID system. Alien enables you to verify the uniqueness and humanness of your users, build persistent privacy-preserving reputation and remove bots from your platform.

Core Concepts

Before you start integrating, it’s important to understand these fundamental concepts:

These concepts are the foundation for how Alien SSO works. We recommend reading these guides before proceeding with integration.

Who is this for?

This documentation is designed for:

  • Web developers building SaaS applications, dashboards, or content platforms
  • Blockchain developers creating Solana dApps, DeFi protocols, or NFT marketplaces
  • Mobile developers integrating authentication into apps with WebView components
  • Backend engineers implementing secure, non-custodial authentication systems

What types of applications can integrate?

Alien Network supports various application types:

Web Apps

  • React, Next.js, Vue or Vanilla JavaScript applications.
  • Traditional web2 apps that need secure verification.
  • Applications that require OAuth2.0/OIDC-compatible identity.
  • Services that need verified user claims (name/avatar).

Solana Applications

  • Decentralized applications (dApps) on Solana.
  • DeFi protocols that require user verification.
  • NFT marketplaces and gaming platforms.
  • Any Solana program that needs on-chain session verification.

Mobile Applications

  • Native iOS/Android apps with WebView integration.
  • Mini apps running inside the Alien native app.
  • Hybrid applications that require deep link authentication.
