Nexus Testnet III will be a staggered release in order to deliver the most stable and performant experience to everyone. Throughout today (23/06/2025), it will go live in the United States, Vietnam, Nigeria, Russia, India, Indonesia, the United Kingdom, and Hong Kong SAR and Mainland China in order.

Customise the deployment​

On the template deployment page, enter your wallet address and select a machine in a region where the testnet has been rolled out.
The recommended specification is 2 vCPU and 8 GB RAM (feel free to select a higher specification).
Note: GPU resources are not utilised by the Nexus CLI, so adding GPU capacity is optional and not required for this deployment.
