Sui networks

Sui operates four network environments:

• Mainnet: Production network. SUI tokens have real monetary value. Use for final deployments.
• Testnet: Mirrors Mainnet features. Free SUI tokens from faucets. Use for integration testing and staging.
• Development network. Free SUI tokens. Use for early-stage development and experimentation.
