Connecting to the Sui Network

Sui offers three main networks for development and testing: Mainnet, Devnet, and Testnet. You can use either Devnet or Testnet to experiment with Sui's features before deploying on Mainnet. Additionally, you can set up a local Sui network for offline development.

Overview of Sui Networks

Sui Testnet and Devnet Features:

• Four validator nodes operated by Mysten Labs.
• Public JSON-RPC endpoint: https://fullnode.devnet.sui.io:443 for transactions and queries.
• Sui Explorer: A blockchain explorer to track transaction history.

Test Token Acquisition:

• Devnet tokens: Request via Discord faucet.
• Testnet tokens: Request via Testnet Discord.
• Localnet tokens: Use curl with your local faucet.

Note: Test tokens have no monetary value. Mainnet does not provide a faucet service.

For announcements, check the #announcements Discord channel. Review Sui's Terms of Service before use.

Tools for Sui Network Interaction

• Sui CLI:

  • Manage private keys.
  • Create NFTs.
  • Deploy Move modules.
• Sui Explorer: Monitor transactions and objects.

Environment Setup

Step 1: Install Sui

Follow the installation guide. Verify installation by running:

Configuring the Sui Client

Default Configuration

Running sui genesis generates client.yaml, connecting to http://0.0.0.0:9000 (Localnet). Modify this file to switch networks.

Connecting to a Network

1. Run:

   sui client

2. Follow prompts to enter an RPC URL (e.g., https://fullnode.devnet.sui.io:443 for Devnet).
3. Assign an environment alias (e.g., devnet).
4. Select a key scheme (ed25519, secp256k1, or secp256r1).

Expected output:

Generated address: 0xb9c83a8b40d...
Recovery Phrase: [12-word mnemonic]

Managing RPC Endpoints

• List environments:

  sui client envs

• Add a custom endpoint:

  sui client new-env --alias <name> --rpc <url>

• Switch networks:

  sui client switch --env <alias>

Troubleshooting: Delete ~/.sui/sui_config and reinstall Sui binaries if errors occur.
