Environment Setup

Before the Relay can be launched, the .env file has to be set up first.

It is located in the folder cloned from Fortytwo Relay Setup .
If you haven’t set it up during the ‘Setting Up the Fortytwo Relay Node’ stage, copy and rename the .env.example reference file.

Environment Parameters

FT_ACCOUNT_PRIVATE_KEY

Paste in the private key of an EVM-compatible Web3 account. You can get it from any Web3 wallet that supports EVM networks.

• Your wallet should be different from your Inference Node wallet. This applies if you participate in both Inference and Relay activities at the same time.
• Keep your Private Key secure. Never share it publicly or commit it to version control systems.

Early participation note:

If the private key you wish to use is not tied to the public wallet address you applied with:

Either

1. Title your letter “Relay Program Participation”.
2. Specify the public wallet address that you registered with.
