Connect to Sui Devnet

Use the Sui Devnet network to experiment with Sui. Please submit feedback about your experience using Devnet, report bugs, and contribute to Sui.

The Sui Devnet network consists of:

  • Four validator nodes operated by Mysten Labs. Clients send transactions and read requests via this endpoint: using JSON-RPC.
  • A public network Sui Explorer for browsing transaction history.

You can request test SUI tokens through the Sui devnet-faucet Discord channel. These coins have no financial value. With each Sui release, the network resets and removes all assets (coins and NFTs).

See announcements about Sui Devnet in the #devnet-updates Discord channel.

See the terms of service for using the Devnet network.


Sui provides the following tools to interact with Sui Devnet:

Environment set up

First, Install Sui. After you install Sui, request SUI test tokens through Discord.

To check whether Sui is already installed, run the following command:

which sui

If Sui is installed, the command returns the path to the Sui binary. If Sui is not installed, it returns sui not found.

See the Sui Releases page to view the changes in each Sui release.

Configure Sui client

If you previously ran sui genesis -f to create a local network, it created a Sui client configuration file (client.yaml) that connects to localhost See Connect to custom RPC endpoint to update the client.yaml file.

To connect the Sui client to Sui Devnet, run the following command:

sui client

The first time you start Sui client, it displays the following message:

Config file ["/Users/dir/.sui/sui_config/client.yaml"] doesn't exist, do you want to connect to a Sui RPC server [y/n]?

Press y and then press Enter. It then asks for the RPC server URL:

Sui RPC server Url (Default to Sui Devnet if not specified) :

Press Enter to connect to Sui Devnet. To use a custom RPC server, enter the URL to the RPC endpoint to use.

Select key scheme to generate keypair (0 for ed25519, 1 for secp256k1):

Type 0 or 1 to select key scheme.

Connect to custom RPC endpoint

If you previously used sui genesis with the force option (-f or --force), your client.yaml file already includes two RPC endpoints: localnet and devnet You can view the defined environments with the sui client envs command, and switch between them with the sui client switch command.

If you previously installed a Sui client that connected to the Devnet network, or created a local network, you can modify your existing client.yaml to change the configured RPC endpoint:

To add a custom RPC endpoint, run the following command. Replace values in < > with values for your installation:

sui client new-env --alias <ALIAS> --rpc <RPC>

To switch the active network, run the following command:

sui client switch --env <ALIAS>

If you encounter an issue, delete the Sui configuration directory (~/.sui/sui_config) and reinstall the latest Sui binaries.


Note that in the following sections, the object ID's, addresses, and authority signatures used are example values only. Sui generates unique values for each of these, so you see different values when you run the commands.

Request test tokens

  1. Join Discord. If you try to join the Sui Discord channel using a newly created Discord account you may need to wait a few days for validation.
  2. Get your Sui client address:
    sui client active-address
  3. Request test SUI tokens in the Sui #devnet-faucet Discord channel.

Send the following message to the channel with your client address: !faucet

Mint an example NFT

To create a Non-Fungible Token (NFT), run:

sui client create-example-nft

The command returns a response similar to the following:

Successfully created an ExampleNFT:

ID: ED883F6812AF447B9B0CE220DA5EA9E0F58012FE
Version: 1
Owner: Account Address ( 9E9A9D406961E478AA80F4A6B2B167673F3DF8BA )
Type: 0x2::devnet_nft::DevNetNFT

The preceding command created an object with ID ED883F6812AF447B9B0CE220DA5EA9E0F58012FE. Use the Sui Client CLI to view objects owned by the address.

To view the created object in Sui Explorer, append the object ID to the following URL

The following command demonstrates how to customize the name, description, or image of the NFT:

$ sui client create-example-nft --url= --description="The greatest chef in the world" --name="Greatest Chef"

The command returns a new object ID:

Successfully created an ExampleNFT:

ID: EC97467A40A1305FFDEF7019C3045FBC7AA31E29

Owner: Account Address ( 9E9A9D406961E478AA80F4A6B2B167673F3DF8BA )

Publish a Move module

This section describes how to publish a sample Move package using code developed in the Sui Move tutorial. The instructions assume that you installed Sui in the default location.

sui client publish <your-sui-repo>/sui_programmability/examples/move_tutorial --gas-budget 30000

The response resembles the following:

The package publish operation does two important things:

  • Creates a package object (with ID 0689E58788C875E9C354F359792CEC016DA0A1B0)
  • Creates a Forge object (with ID 898922A9CABE93C6C38C55BBE047BFB0A8C864BF) as a result of running a module initializer for the one (and only) module of this package.

When you publish a package, the IDs for the objects created are different than the ones displayed in this example. This remainder of this topic uses <PACKAGE_ID> and <FORGE_ID> to represent the IDs for the created objects. You must replace these with the values for your package.

Make a Move call

This section describes how to call into functions defined in the package published in the previous section. Use the (<PACKAGE_ID>) and (<FORGE_ID>) values from your package to create swords and transfer them to other players.

To demonstrate this, <PLAYER_ADDRESS> represents the address of the player to receive a sword. You can use an address of someone you know, or create another address for testing with the following Sui Client CLI command:

sui client new-address ed25519

The command returns the following message and a 12 word recovery phrase for the address:

Created new keypair for address with scheme Secp256k1: [0x568318261d88535009dff39779b18e1bfac59c33]
Secret Recovery Phrase : [mist drizzle rain shower downpour pond stream brook river ocean sea suinami]

To create a sword and transfer it to another player, we use the following command to call the sword_create function in the my_module module of the package we previously published.

You must use the same format for the command and function parameters as the example shown.

sui client call --function sword_create --module my_module --package 0x<PACKAGE_ID> --args \"0x<FORGE_ID>\" 42 7 \"0x<PLAYER_ADDRESS>\" --gas-budget 30000

Go to the Sui Explorer to observe a newly created object. You should see a sword object created with Magic property of 42 and Strength property of 7 and transferred to the new owner.

Replace the object ID in the Explorer with the object ID of the created object you observed in your own command output, appended to:
