Fortytwo Network

​
Devnet Program

To receive an activation code, fill out our participation form at https://tally.so/r/wQzVQk. You will receive a single-use activation code in an e-mail. For more, read on ‘Participate in the Devnet Program ’ page.
If you haven’t used it yet, ping our support team on Discord . If you’ve already activated it, just use your private key or recovery phrase to log in.
Yes. Just follow this ‘Quick Start’ guide. With no activation code, you’ll need to manually monitor and top-up MON and FOR balance for your node to work, with 2 MON and 100 FOR required to start the node. Your node will not automatically receive MON refills with no activation code.
No. Invite codes are one-time use only.
It depends on how you partcipate in the network:

Case A: Your node receives automated gas compensation for participation.

Do not transfer MON out of your wallet in this case. This will terminate the compensation cycle on your node and you will have to fund your participation by yourself. You will not be able to return to the compensation program again. Your participation in Devent program will continue as usual as long as there is enough MON to pay for gas.

Case B: You cover your node's gas consumption manually.

You are free to refill and transfer MON out of your wallet as needed.
You can read more on ‘Holding MON in Your Wallet’ page.
If you used an activation code, your wallet is usually refilled within 24 hours. If it’s been longer, message us on Discord . Reminder: auto-refill works only for wallets tied to activation codes.

​
Running the Node

No. To avoid issues with your node, only run one node instance per machine. Note that using Fortytwo CLI and Fortytwo App counts as two node isntances.
No. Only one node per wallet is supported. You will face issues or node inactivity if you attempt to use the same wallet on several nodes simultaneously.
Not at this time. We support only GPU-based nodes due to performance requirements.
It depends on a few factors like machine specs, internet connection speed and current system load. Try a few available models to see what works best on your setup.For more, read ‘Selecting a Model for Your Node’.
You receive FOR tokens for every round of inference won by your node.
This could be due to connection issues, or low request volume in the network. Try restarting the node or switching to a different model. Sometimes it just needs a bit of time. If it’s been over 24 hours with no FOR earnings, reach out to us on Discord .
Yes, but an Nvidia GPU is required. CPU-only machines are not supported at this time. Read ‘Hardware Requirements’ for your system.
Export your private key and Secret Recovery Phrase from your virtual machine. If your VPS is lost, you will lose access to your node if your credentials are not exported.
We do not recommend using custom scripts unless you are fully confident in their origin and completely understand their functionality.
We cannot guarantee your privacy and security in this case or support should any issues arise.

​
Node Applications

Yes. With the CLI app version you can use any model in GGUF format, just follow the instructions when starting your node. Yes. The nodes support models in GGUF format.
  • >_ Fortytwo CLI
  • ::|| Fortytwo App
When choosing a model, you are offered to Import a custom model via ✶ IMPORT CUSTOM option. You can either import model from a repo (Hugging Face, for example), or pick a locally downloaded GGUF model file. Follow the instructions in your CLI node.
There are usually two scenarios:
  1. Free up resources taken by other applications. Closing ‘expensive’ processing applications such as 3D editors, video editors and video games might help.
    Then launch the node again and select your model. If you are manually controlling the KV Cache size, you can now reopen the applications that you closed.
  2. Try selecting a model that is about 2GB smaller than your total memory size. Bear in mind that, in addition to your model, memory will also be used by the KV Cache and the default processes of your OS.
See our ‘Selecting a Model for Your Node’ article for details.
Restarting your other applications should help.When you launch a resource-intensive application while your node is running, the application may only detect the currently available resources. Therefore, when you stop the node, your other application is unable to detect any additional resources that got freed up and may continue to experience issues until it is restarted.
Default installation paths are relative to your home directory.
  • >_ Fortytwo CLI
  • ::|| Fortytwo App
The path where your node is installed might differ from the default path if you altered it at the node installation step as defined on the ‘Quick Start’ page.
On October 23, 2025, we’ve changed the name of the default folder from Fortytwo to FortytwoCLI. If you’ve installed your Fortytwo CLI before this date, your default path will differ. To access the folder, look for Fortytwo instead of FortytwoCLI.
  • macOS
  • Windows
  • Linux (Ubuntu/Debian)
Short path:
Zsh
    ~/FortytwoCLI
Full path:
