Environment Variables​

The engine supports various environment variables for configuration. Here are some key examples:

IOTA DLT Configuration​

Basic IOTA configuration:

# IOTA Node Configuration
IOTA_NODE_ENDPOINT="https://api.devnet.iota.cafe"
IOTA_FAUCET_ENDPOINT="https://faucet.devnet.iota.cafe"
IOTA_EXPLORER_ENDPOINT="https://explorer.iota.org/"
IOTA_NETWORK="devnet"
IOTA_COIN_TYPE="4218"

IOTA Gas Station Configuration (Optional)​

The IOTA Gas Station pattern allows for sponsored transactions and improved UX:

# Gas Station Configuration
IOTA_GAS_STATION_ENDPOINT="https://gas-station.example.com"
IOTA_GAS_STATION_AUTH_TOKEN="your-auth-token"

Configuration Options:

  • IOTA_GAS_STATION_ENDPOINT: The URL of the gas station service
  • IOTA_GAS_STATION_AUTH_TOKEN: Authentication token for the gas station

When gas station is configured, all IOTA-related connectors (wallet, nft, verifiable-storage, identity, identity-resolver) will automatically use the centralized configuration and have access to gas station functionality.
