Home Digital Identity Extrimian’s Guide to SSI for Developers

Introduction to Technical Documentation

If you’re a developer looking to dive into decentralized digital identity (SSI), Extrimian provides the resources you need. Our detailed guides and practical examples help you understand and use our tools effectively.

Learn, Practice, and Develop with ID Connect

Extrimian’s documentation covers essential topics that simplify your work with Self-sovereign Identity. Here’s a quick rundown of what you can expect:

1. Creating Decentralized Identifiers (DIDs)

Discover how to create and manage DIDs, which let users establish their own secure and unique identifiers without relying on central authorities.

2. Managing Verifiable Credentials (VCs)

Our guides explain how to issue, store, and check verifiable credentials. This is crucial for organizations that need to issue trusted digital certificates and for users who need to prove their authenticity.

3. Using Extrimian ID Connect

Get step-by-step instructions on integrating SSI functionalities into your applications with Extrimian ID Connect. This includes how to generate invitations, handle messages, and publish DIDs on the blockchain.

// Ejemplo de publicación de un DID
const { Did } = require("@extrimian/did-registry");
const didService = new Did();
const createDidResponse = await didService.createDID({
  // Configuración del DID
