Authentication

Self provides a secure authentication workflow that allows users to authenticate themselves using their digital identity. This workflow is designed to be scalable and can be used in a variety of scenarios, including web applications, mobile apps, and enterprise systems.

Key Features:

  • Passwordless authentication using biometric credentials
  • Liveness detection to prevent spoofing
  • Privacy-preserving verification without storing personal data
  • Cross-platform compatibility (iOS, Android, Web)

Identity Verification

The Self SDK provides streamlined identity verification flows for mobile applications. These flows support the capture and validation of various identity documents including passports, ID cards, and driving licenses.

Key Features:

  • NFC chip reading for enhanced passport verification
  • Pre-built UI components for document capture
  • Secure local storage of verified credentials
  • Support for multiple document types and formats

Digital Signatures

Self enables secure digital document signing workflows that provide legally-compliant electronic signatures. Users can cryptographically sign documents using their verified digital identity, ensuring document integrity and non-repudiation.

Key Features:

  • Cryptographic document signing with digital identity
  • Tamper-proof signatures with audit trails
  • Legal compliance for electronic signatures
  • Document integrity verification using cryptographic hashes

Working Code Examples

All use cases are demonstrated through open source implementations that showcase real-world usage of Self SDK. These examples are designed as complete, functional applications that you can run and test immediately.

Self SDK Examples Repository

Our examples repository provides fully functional implementations across multiple platforms:

Mobile Peers (Frontend):

  • Android: Complete Android SDK implementations with UI flows (android/ folder)
  • iOS: Swift examples with proper async/await patterns (ios/ folder)

Server Peers (Backend):

  • Golang: Backend integration examples with full workflows (golang/ folder)
  • Java: Enterprise-ready server implementations (java/ folder)

Quick Start - Try Examples Immediately

For instant testing without building from source, use our pre-compiled binaries and applications:

Platform Quick Install Source Code
Mobile - Android Download APK View Source
Mobile - iOS Download from App Store View Source
Server - Golang docker run -it ghcr.io/joinself/self-sdk-demo:go View Source

git clone --recurse-submodules https://github.com/joinself/self-sdk-examples.git

# Or if already cloned, initialize submodules
git submodule update --init --recursive

📂 Repository Structure

Each platform's examples are organized in dedicated folders within the repository:

Platform Example Location Type Description
Android android/ Mobile Peer Complete Android apps demonstrating all SDK features
iOS ios/ Mobile Peer Native iOS implementations with SwiftUI
Golang golang/ Server Peer Backend Go implementations with full workflows
Java java/ Server Peer Enterprise Java server examples

This structure provides both server peers (backend) and mobile peers (frontend) that can interact with each other, giving you a complete Self network for testing and development.
