Setup

Prerequisites

• Python 3.8 or higher
• pip (Python package installer)
• nillion-devnet for local development
• a funded Nilchain private key for Testnet development

Installation

1. Clone the repository:

2. Create and activate a virtual environment:

   python3 -m venv .venv
   source .venv/bin/activate  # On macOS/Linux
   .venv\Scripts\activate     # On Windows

3. Install the required packages:

   pip install -r requirements.txt

Configuration

Local Development with nillion-devnet

For local development, simply run nillion-devnet and make sure that all .streamlit/sects.toml variables are commented out. Because these aren't present, the app will automatically use your local devnet configuration and payment key.

Connecting to Nillion Testnet

To connect to the Nillion testnet:

1. Create a streamlit secrets file:

   mkdir -p .streamlit
   cp .streamlit/secrets.example.toml .streamlit/secrets.toml

2. Edit .streamlit/secrets.toml to add a valid Nillion Network configuration and a funded Nilchain key

Also add a Base Sepolia enabled Alchemy API Key to the file - alchemy_api_key

Running the App

Start the local streamlit app:

streamlit run app.py
