Get Started

Prerequisites

• Node.js 18 or higher

• npm or yarn

• (Optional) Solana CLI for local dev and key management

Installation

Option A: Global install (recommended for CLI use)

npm install -g @eternallabs/netauth

Then run the CLI from anywhere:

netauth --help
netauth agent register my-agent

Option B: Local / project install

git clone https://github.com/eternal-labs/net-auth.git
cd net-auth
npm install

Use the CLI via npm script:

npm run netauth -- --help

Configuration

1. Copy the example environment file:

   cp .env.example .env

2. Edit .env with your values:

   Variable	Description	Required
   SOLANA_RPC_URL	Solana RPC endpoint (e.g. https://api.mainnet-beta.solana.com)	Yes (for live)
   NETWORK	mainnet-beta, devnet, or testnet	No (default: mainnet-beta)
   ENCRYPTION_KEY	Secret used to encrypt wallet private keys	Yes (for wallet creation)
   PORT	HTTP port for the API server	No (default: 3000)
   X402_ENDPOINT	x402 protocol endpoint	No (optional; fallback used if unset)
   X402_API_KEY	API key for x402 service	No (if using x402 endpoint)

3. Important: Without ENCRYPTION_KEY, the server will not start (wallet creation requires it). The CLI can still show help without it.

Running the Server

Development (with watch):

npm run dev

Production:

npm run build
npm start

The API is available at http://localhost:3000 (or your configured PORT). Health check:

curl http://localhost:3000/health

Quick Start Flow

1. Start the server (with ENCRYPTION_KEY set).

2. Register two agents:

   netauth agent register alice
   netauth agent register bob

3. Check balance:

   netauth agent balance alice --sol

4. Send a payment:

   netauth payment send alice bob 0.1 --sol --memo "First payment"

5. View history:

   netauth payment history alice
