Nexus Testnet is a decentralized network focused on zero-knowledge proofs and AI computation, allowing users to contribute computing resources (proof cycles) via nodes or provers to earn points or tokens during its testnet phases. As of August 2025, Nexus Testnet III is active, offering opportunities to earn NEX tokens before the mainnet launch. This guide covers the sign-up process and various ways to use the testnet, inspired by introductory resources from the Nexus blog. Note that details may evolve, so check official sources like the Nexus Dashboard for updates.
Step 1: Sign Up for a Nexus Testnet Account
- Visit the Nexus Dashboard at https://app.nexus.xyz.
- Choose to sign up using your email address or connect an EVM-compatible wallet (e.g., MetaMask or Rabby).
- If using email, enter your email and confirm it via the verification link sent to your inbox. This creates your ProverID and Nexus account.
- Link your wallet if not done during sign-up to track rewards and participate fully.
This process is quick and free, and your account will accumulate points from all devices or nodes you connect.
Step 2: Choose Your Method to Use the Nexus Testnet and Contribute
There are three main ways to participate: via browser (easiest for beginners), CLI on your own server, or renting a node. Contributing involves running a node to provide proof cycles, which earns you Nexus points (1000 points = 1 NEX token in Testnet III).
Option 1: Browser Node (Simple, No Setup Required)
- After signing in to https://app.nexus.xyz, click the toggle switch or “Launch Network” button to start contributing.
- Click “Connect” and ensure your browser remains open and active.
