Nexus Layer 1 Devnet
Devnet was a live developer-facing test environment. It is now closed and transitioning to Testnet III.
Devnet is officially closed. Devnet ran from February 22 to June 20, 2025. Testnet III is opening soon. Your NEX Devnet Points and NEX Devnet Tokens are being preserved and will be accessible through the rewards system.
This page explains the transition from Nexus Layer 1 Devnet to Testnet III. This documentation covers the Devnet closure and how we’re moving forward to Testnet III.
Devnet
The Nexus Devnet was a testing environment for experimental features from February 22 to June 20, 2025. By design, NEX Devnet Points were for testing purposes.
Devnet is officially closed as of June 20, 2025. Here’s what this means for participants:
What Happens to NEX Devnet Points
All users with NEX Devnet Points have been converted to Devnet Tokens and are now available in their wallet.
During Devnet, users earned Devnet Points by proving via Nexus OS or CLI and then claimed them to convert them into Devnet Tokens.
Important: Everyone who participated in Devnet now has all their Devnet Points converted to Devnet Tokens in their wallets. If you had unclaimed Devnet Points, don’t worry - the system auto-claimed them for you, so you didn’t lose anything.
Testnet III launch
When Testnet III launches, certain areas that used to show NEX Devnet Points and Devnet Tokens will now show NEX Testnet III Points and Testnet III Tokens.
Proving via Nexus OS or CLI
When you start to prove via Nexus OS or CLI, you will earn NEX Testnet III Points, not NEX Devnet Points.
Because Testnet III is a new environment, you will not have any Testnet III Points at the start. You cannot convert NEX Devnet Points to NEX Testnet III Points.
Nexus OS wallet
The Nexus OS wallet will show NEX Testnet III Tokens, not NEX Devnet Tokens.
Accessing Old NEX Devnet Points and Devnet Tokens
Viewing NEX Devnet Points
Once Testnet III starts, users can view their Devnet history in the rewards page https://app.nexus.xyz/rewards, alongside their Testnet I and Testnet II records.
Accessing NEX Devnet Tokens
To view or access a NEX Devnet Tokens, configure MetaMask with these network settings:
Log in to Nexus
Open app.nexus.xyz and sign in using your email or external wallet.
Add a New Network
In your wallet (e.g., MetaMask), manually add the Nexus Chain using the network parameters provided in the app.
Start Transacting
Once connected, you can begin sending Devnet Tokens, deploying contracts, and interacting with Nexus-native applications directly from your wallet or CLI tools.
