Before you begin working with NullGraph, ensure you have the following tools installed and configured on your system.

​
Required Software

​
Rust

NullGraph’s Solana program is written in Rust. Install the latest stable version using rustup: 
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Verify the installation: 
rustc --version

​
Solana CLI

The Solana command-line tools are required for deploying and interacting with the program. Version Required: v1.18 or higher 
sh -c "$(curl -sSfL https://release.solana.com/stable/install)"
Verify the installation: 
solana --version
After installation, you may need to add Solana to your PATH. Follow the instructions displayed after the installation completes.

​
Anchor CLI

NullGraph uses Anchor framework for Solana program development. Version Required: v0.31.1 Install via cargo: 
cargo install --git https://github.com/coral-xyz/anchor --tag v0.31.1 anchor-cli
Verify the installation: 
anchor --version

​
Node.js

The frontend application and build scripts require Node.js. Version Required: v18 or higher Download and install from nodejs.org or use a version manager like nvm: 
# Using nvm
nvm install 18
nvm use 18
Verify the installation: 
node --version
npm --version

​
Wallet Setup

​
Phantom Wallet

NullGraph requires a Solana wallet for transaction signing. Install the Phantom browser extension:
  1. Visit phantom.app
  2. Download and install the browser extension
  3. Create a new wallet or import an existing one
  4. Important: Switch your Phantom wallet to Devnet
    • Open Phantom
    • Click Settings (gear icon)
    • Select “Developer Settings”
    • Change network to “Devnet”
NullGraph currently deploys to Solana Devnet. Ensure your wallet is set to Devnet before interacting with the application to avoid transaction errors.

​
Solana Wallet for Deployment

If you plan to deploy the program yourself, you’ll need a filesystem wallet with devnet SOL: 
# Generate a new keypair
solana-keygen new --outfile ~/.config/solana/nullgraph.json

# Airdrop devnet SOL for deployment
solana airdrop 2 --url devnet

​
System Requirements

  • Operating System: Linux, macOS, or Windows (with WSL2)
  • Memory: At least 8GB RAM recommended
  • Disk Space: 10GB free space for dependencies and build artifacts

​
Next Steps

Once you have all prerequisites installed, proceed to Setup to build and deploy NullGraph.
