Quickstart

Get up and running with a verifiable, zero-knowledge authentication flow in just four steps. We'll use Next.js for this example.

1

Install Dependencies

Add the Solidus SDK and auth primitives to your project.

2

Issue a Challenge

On the server, mint a one-time challenge for the DID that wants to log in.

3

Verify the Presentation

Verify the W3C Verifiable Presentation the wallet signs in response to the challenge.

4

Client Login Flow

Fetch a challenge, sign it with the user’s wallet, then post the presentation back.

bash
npm install @solidus-network/sdk @solidus-network/auth
