Note: An organization is automatically created upon first login. All resources and billing are organization-scoped.

Wallet Funding​

Substrate AI Cloud uses a prepaid wallet system. Funds must be added before launching instances.

Important: The first hour is charged immediately upon instance launch. Insufficient balance causes instance suspension.

Add Funds​

  1. Navigate to Wallet page
  2. Click "Add Funds"
  3. Complete payment via Stripe
  4. Funds appear instantly

Minimum deposit: €10

Your wallet balance and transaction history are displayed in the wallet dashboard.

SSH Keys​

At least one SSH key is required for instance authentication.

Option 1: Upload Existing Key​

  1. Go to SSH Keys page
  2. Click "Add SSH Key"
  3. Enter a descriptive name
  4. Paste your public key content

Locate your public key:

# Linux/macOS
cat ~/.ssh/id_rsa.pub
# Windows PowerShell

Option 2: Generate New Key​

Let the platform generate a key pair:

  1. Click "Generate SSH Key"
  2. Enter a descriptive name
  3. Download both keys immediately
