To switch between Testnet and Mainnet using the Sui CLI, you can use the --network flag to specify the desired network when running commands. Key Commands: Switch to Testnet: sui client set-config --network testnet Switch to Mainnet: sui client set-config --network mainnet This will configure the CLI to interact with either the Testnet or Mainnet, depending on your choice. CLI Usage Example: Deploying on Testnet: sui client publish --network testnet --package Deploying on Mainnet: sui client publish --network mainnet --package Best Practices: Ensure youre using the correct network for deployment to avoid unintentional actions on the wrong chain. Always test on Testnet before deploying on Mainnet to ensure correctness.

To switch between Testnet and Mainnet using the Sui CLI, you need to update your active environment using sui client switch. The Sui CLI manages environments via configuration profiles, each pointing to a different RPC endpoint. Steps: List available environments: sui client active-address Switch to Testnet: sui client switch --env testnet Switch to Mainnet: sui client switch --env mainnet Verify the environment: sui client active-env If you need custom RPC URLs or want to create your own profile (e.g., for localnet), edit the ~/.sui/sui_config/client.yaml file or use: sui client new-env --alias localnet --rpc http://127.0.0.1:9000 Notes: Make sure your wallet is funded on the network you’re working with. Testnet and Mainnet addresses are separate; tokens or objects do not carry over. Be cautious not to deploy test code to Mainnet without full audit and testing. This approach allows clean switching between environments for debugging, deploying, and interacting with smart contracts or other assets under realistic test conditions.

To switch between Testnet and Mainnet in the Sui CLI, use the sui client switch command followed by the desired environment (e.g., sui client switch --env mainnet). Alternatively, manually configure the RPC endpoint in client.yaml or via sui client new-env to define custom networks. Unlike EVM chains where network switching often relies on provider URLs, Sui’s CLI maintains explicit environment profiles, reducing accidental cross-network deployments. Always verify your active network with sui client active-env before executing transactions to avoid testnet/mainnet confusion.

To switch between Testnet and Mainnet using the Sui CLI, you need to change the active RPC endpoint in your Sui client configuration. You do this by using the sui client switch command along with a specified environment like testnet, mainnet, or a custom URL. If you installed Sui CLI properly, you can quickly switch to the Testnet by running sui client switch --env testnet, or to the Mainnet using sui client switch --env mainnet. This changes the RPC endpoint your local CLI connects to, which affects all subsequent transactions, queries, or deployments. You can also use a custom endpoint if youre running a fullnode or want to target a specific public node by using --rpc . To confirm your current setup, you can run sui client active-address and sui client envs to see the current environment settings. Switching networks is essential when deploying Move packages, testing smart contracts, or querying live data on different chains. Always double-check the network before submitting real transactions to avoid loss of funds or deploying test code to production.

To switch between Testnet and Mainnet in the SUI CLI, you need to set the appropriate network for your commands. This is done by specifying the network URL or using a configuration file. Heres how to do it: Switching Between Testnet and Mainnet Using SUI CLI Set Network for SUI CLI: The sui CLI uses environment variables to determine the network. You can switch between Testnet and Mainnet by setting the environment variable for the SUI_ENV network or using the --network flag in your commands. Option 1: Set via Environment Variable You can set the SUI_ENV environment variable to either testnet or mainnet. For Testnet: export SUI_ENV=testnet For Mainnet: export SUI_ENV=mainnet Once the environment variable is set, the SUI CLI will use the corresponding network for all subsequent commands. Option 2: Set via Command Line Flag (--network) For each command, you can specify the network using the --network flag: For Testnet: sui client --network testnet For Mainnet: sui client --network mainnet Example Command: To publish a package on Testnet: sui client publish --gas-budget 10000 --network testnet To publish a package on Mainnet: sui client publish --gas-budget 10000 --network mainnet Common Errors to Watch For: Incorrect Network: If you try to interact with the wrong network, your transactions may fail or be sent to the wrong chain. Configuration Issues: Ensure the SUI_ENV environment variable is set correctly or that youre using the right flag for each command. Best Practices: Environment-Specific Configuration: Set the network environment variable at the start of your session to avoid having to specify --network for every command. Test Before Mainnet: Always test your contract or transaction on Testnet before deploying to Mainnet. By following these steps, you can easily switch between Testnet and Mainnet in the SUI CLI to interact with the appropriate environment for your development or production needs.

To switch between Testnet and Mainnet using the Sui CLI, you need to update the active environment profile that your CLI uses to interact with the Sui network. You do this by specifying a --env flag in commands or by setting the environment using the configuration profile. Sui CLI supports predefined environments like testnet, mainnet, and localnet. If you want to switch permanently, use the following command: sui client switch --env testnet or sui client switch --env mainnet This changes the default fullnode URL and configuration in your CLI profile. You can also verify or edit your CLI settings by checking the ~/.sui/sui_config/sui_client.yaml file. This is where endpoint URLs, active addresses, and keypairs are stored. Alternatively, you can override the endpoint temporarily without switching the profile using: sui client call --url https://fullnode.testnet.sui.io:443 or for Mainnet: sui client call --url https://fullnode.mainnet.sui.io:443 Make sure your wallet or keypair has assets on the corresponding network, as each environment maintains its own state and assets. Also, avoid using Testnet keys or addresses on Mainnet for security and data separation.

To switch between Testnet and Mainnet in the Sui CLI, update your active network configuration using the sui client switch command: Switch to testnet sui client switch --network testnet Switch to mainnet sui client switch --network mainnet Check current network sui client active-address The CLI uses predefined network endpoints (testnet: https://fullnode.testnet.sui.io:443, mainnet: https://fullnode.mainnet.sui.io:443). Configuration is stored in ~/.sui/sui-config/client.yaml. Critical considerations: Use separate wallets/addresses for testnet vs mainnet Testnet SUI has no value; obtain via faucet: sui client faucet-request Mainnet requires real SUI for gas (use trusted exchange or wallet) Always verify network before signing transactions Move packages published on one network are not automatically available on another This network isolation ensures security and prevents accidental mainnet deployments during development.

To switch between Testnet and Mainnet in Sui CLI, use the sui client switch command. This command updates the active environment to either testnet, mainnet, or another configured endpoint. First, make sure you have installed the Sui CLI and initialized your wallet using sui client init. To switch to testnet, run sui client switch --env testnet. To switch to mainnet, use sui client switch --env mainnet. You can confirm your current environment by running sui client active-env. Each network has separate addresses and object states, so assets on testnet do not appear on mainnet. You can also define a custom environment using sui client new-env --alias --rpc . All environment settings are stored in the client.yaml file in your Sui config directory. Be careful when deploying contracts to mainnet, and always test thoroughly in testnet or localnet first.

Tucker · Answer

To switch between Testnet and Mainnet using the Sui CLI, you modify the active environment profile in your CLI configuration. The Sui CLI uses a sui_config/sui_config.yaml file to manage connections to different networks. This file holds multiple environments (Mainnet, Testnet, Devnet, and Localnet), and you can switch between them as needed. Steps to Switch Network: View Current Active Environment: sui client active-env List Available Environments: sui client envs Switch to Testnet: sui client switch --env testnet Switch to Mainnet: sui client switch --env mainnet Optional: Add a Custom RPC Endpoint (if needed): sui client new-env --alias customnet --rpc sui client switch --env customnet Architecture Concept: Each environment uses a separate RPC URL to talk to the Sui network. Mainnet and Testnet have different object states, packages, and coin values. Smart contracts deployed on Testnet will not exist on Mainnet unless you explicitly deploy them again. Move Development Consideration: When writing or testing Move code, you usually deploy it with: sui client publish --gas-budget 100000000 Make sure youre connected to the correct environment before publishing or interacting with packages. Common Mistakes: Forgetting to switch environments and publishing to the wrong network. Using testnet faucet or coins on mainnet where they’re invalid. Assuming package addresses are the same across networks—they are not. Best Practice: Always confirm the active network before performing actions: sui client active-env Keep a separate sui_config.yaml backup for each network if youre managing multiple projects. This ensures you avoid deploying or calling contracts on the wrong chain.

To switch between Testnet and Mainnet using the Sui CLI, you just change the active environment profile, which tells the CLI which RPC URL and network settings to use. Sui CLI supports multiple environments like testnet, mainnet, devnet, and localnet, and each one has a different RPC and faucet configuration stored in your Sui config file. You can view your current profile by running: sui client active-env To switch to Testnet: sui client switch --env testnet To switch to Mainnet: sui client switch --env mainnet If you haven’t set them up before, the CLI will automatically fetch the correct RPC URLs and network settings from Sui’s default config endpoints. After switching, all your commands like publishing, transferring, and querying will point to that selected network. Each profile has its own wallet and key storage, so if you’ve funded your address on Testnet, it won’t automatically carry over to Mainnet—you’ll need a separate wallet or import your keys manually if needed. What makes this different from EVM chains is that Sui treats environments more like separate profiles instead of just different RPC endpoints. This means the CLI abstracts the RPC selection for you, making network switching smoother but requiring awareness of which environment your wallet and package IDs belong to. Common mistakes include trying to use a Testnet object on Mainnet (IDs won’t exist), not switching before deploying or funding, or using the wrong gas budget since fees differ slightly across networks.

To switch between Testnet and Mainnet using the Sui CLI, you can specify the network when starting or interacting with the Sui node. Heres how you can switch between the two networks: 1. Starting the Node on Testnet or Mainnet When you start a Sui node using the CLI, you can specify the network by using the --network flag. For Testnet: sui node start --network testnet For Mainnet: sui node start --network mainnet This command will start the Sui node on the corresponding network. 2. Switching Networks for RPC Interactions If you want to interact with Testnet or Mainnet RPC servers using the Sui CLI, you need to set the appropriate endpoint for the network you want to connect to. For Testnet: To interact with the testnet, you can set the RPC endpoint as https://fullnode.testnet.sui.io:443. Example command: sui client --url https://fullnode.testnet.sui.io:443 For Mainnet: To interact with the mainnet, you can set the RPC endpoint as https://fullnode.mainnet.sui.io:443. Example command: sui client --url https://fullnode.mainnet.sui.io:443 You can also set this as your default for the current session. 3. Changing Default Network (Persistent Setting) To change the default network configuration in a persistent way, you can modify the configuration file for the Sui CLI: Open the Sui CLI config file (~/.sui/config.toml on Linux/macOS or C:\Users\AppData\Local\sui\config.toml on Windows). Look for the network or rpc section. Update the rpc endpoint and the network name to the appropriate value (Testnet or Mainnet). For example, to use Testnet: [network] rpc = https://fullnode.testnet.sui.io:443 To use Mainnet: [network] rpc = https://fullnode.mainnet.sui.io:443 4. Verifying the Network Connection You can verify the connection to the desired network by using the following command to check the current state of the network: sui client --url https://fullnode.testnet.sui.io:443 status Or for Mainnet: sui client --url https://fullnode.mainnet.sui.io:443 status This will return details about the connected network, which will help you confirm that youre on the correct network. Conclusion Switching between Testnet and Mainnet in the Sui CLI is straightforward using the --network flag when starting the node, or by specifying the correct RPC endpoint for your commands. You can also modify the configuration file to set a persistent network for your CLI session.
