# ======================= ON-SERVER DEPLOYMENT PARAMETERS =======================
REMOTE_USER=
REMOTE_HOST=

# OPTIONS: development / production
DEPLOYMENT_MODE=production
# development mode installs all services without enabling or starting them automatically, while
# production mode enables and starts all services once the installation is completed.

DB_USERNAME=root
DB_PASSWORD=admin
# If you are running an installer on a fresh instance, this password will be set for the root user.


# =========================== BLOCKCHAIN PARAMETERS ============================
BLOCKCHAIN_ENVIRONMENT=testnet
# Choose between “mainnet” or “testnet”.

DEFAULT_PUBLISH_BLOCKCHAIN=neuroweb
# Blockchain which will be used for publishing Knowledge Assets.
# OPTIONS: neuroweb, base or gnosis
PUBLISH_WALLET_01_PUBLIC_KEY=xxxxxxxxxxxxxxx
PUBLISH_WALLET_01_PRIVATE_KEY=xxxxxxxxxxxxxxx

# Provide up to 3 keys which will be used for publishing Knowledge Assets to
# the default blockchain you defined in DEFAULT_PUBLISH_BLOCKCHAIN.
# Keys provided here require both TRAC and the utility token of the chosen blockchain (e.g., for Base, TRAC and ETH).


# =========================== NODE ENGINE PARAMETERS ============================
# Parameters in this section are related to your node engine configuration where you can
# set up your node’s name for each supported blockchain, as well as management and operational keys (wallets).

# Management (Admin) key will allow you to configure ASK, Operator fee, and other parameters.
# The operational key is used by the node to run certain blockchain operations.
# These wallets WILL NOT be used for publishing operations.

NEUROWEB_OPERATIONAL_KEY_PUBLIC_ADDRESS=xxxxxxxxxxxxxxx
NEUROWEB_OPERATIONAL_KEY_PRIVATE_ADDRESS=xxxxxxxxxxxxxxx
# Note: Neuroweb Management and Operational keys (wallets) require a small amount of NEURO in order to be functional.

# BASE:

# GITHUB CREDENTIALS:
REPOSITORY_USER=
REPOSITORY_AUTH=
# If you want to deploy your private GitHub repositories, provide your GitHub username and token
# for the installer to be able to clone and install your custom Edge Node services.

# =================== EDGE NODE EXTERNAL SERVICES AND TOOLS ====================
# Some Edge Node components rely on LLMs to function properly. To ensure
# full functionality, at least one of the following external services is
# required - OPEN_AI_KEY  or ANTHROPIC_API_KEY

# OpenAI - used by default (https://platform.openai.com/api-keys)
OPENAI_API_KEY="sk-proj-xxxxxxx"

# Anthropic - can be obtained at https://console.anthropic.com/account/keys
