Experiment with Sui Devnet

Welcome to the beginnings of the Sui Devnet. It exists now to gain operational experience with the Sui software in a public setting. The Sui Devnet currently consists of:

Many improvements to the Sui Devnet are underway, such as the ability to run full nodes and use a browser-based wallet. See the Sui Devnet blog post announcement for full details on upcoming features. All Devnet usage is subject to our terms of service.


We provide the following tools for users to interact with the Sui Devnet:


Set up environment

You may simply install Sui and then request test tokens as described in the install docs. To use the Sui Devnet, you will need:

  1. Sui test coins (tokens) requested through Discord.
  2. the git command line interface.
  3. Sui binaries in your PATH environment variable, particularly sui .

Remember, you can confirm the existence of a command in your PATH by running which followed by the command, for example:

$ which sui

You should see the path to the command. Otherwise, reinstall.

Tip: To reliably test Devnet with the latest Sui binaries, re-install them at least weekly.

In addition, to conduct advanced work such as publishing a Move module or making a Move call, also obtain the Sui source code; for simplicity, we recommend installing in ~/sui or using an environment variable.

Set up Sui CLI client, connect to gateway

Now set up your Sui CLI client and connect to Devnet in a single step. Note you can manually change the Gateway URL if you have already configured a Sui CLI client.

Tip: If you run into issues, reset the Sui configuration by removing its directory, by default located at ~/.sui/sui_config. Then reinstall Sui binaries.

Basic testing

Request gas tokens

  1. Join Discord If you haven’t already.
  2. Find your address by running:
    $ sui client active-address
  3. Request tokens in the #devnet-faucet channel per the SUI tokens install documentation.

Mint an example NFT

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

$ sui client create-example-nft

You will see output resembling:

Successfully created an ExampleNFT:

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

The above command created an object with ID ED883F6812AF447B9B0CE220DA5EA9E0F58012FE. Note you may use Sui CLI client to view objects owned by the account.

Now you can view the created object in the Sui Explorer by appending the object ID to: https://explorer.devnet.sui.io/objects/

Example NFT

Note you may easily customize the name, description, or image of the NFT upon creation, like so:

$ sui client create-example-nft --url=https://user-images.githubusercontent.com/76067158/166136286-c60fe70e-b982-4813-932a-0414d0f55cfb.png --description="The greatest chef in the world" --name="Greatest Chef"

Which results in a new object ID:

Successfully created an ExampleNFT:

ID: EC97467A40A1305FFDEF7019C3045FBC7AA31E29
Version: 1
Owner: Account Address ( 9E9A9D406961E478AA80F4A6B2B167673F3DF8BA )
Type: 0x2::devnet_nft::DevNetNFT

That you can similarly view at: https://explorer.devnet.sui.io/objects/EC97467A40A1305FFDEF7019C3045FBC7AA31E29

Custom NFT

See all transactions on the home page and find the transaction hash under Latest Transactions:

Explorer home

To get to the Transaction Details view in Sui Explorer after minting an NFT, click on the Last Transaction ID field in the Object View.

Advanced testing

Publish a Move module

Publish a sample Move package containing code developed in the Sui Move tutorial as follows (assuming you installed the source code in ~sui as advised in set up):

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

You will see this output:

Updated Gas : Coin { id: 58C4DAA98694266F4DF47BA436CD99659B6A5342, value: 49552 }

Two important things happened as a result of publishing this package:

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

Specific object IDs displayed above may differ from one Sui installation to the other, so we will use the following placeholders for them (respectively): <PACKAGE_ID> and <FORGE_ID>. Whenever you see these used in the command line, for example when calling Move functions in the next section, replace them with actual object IDs.

Make a Move call

In the previous section, we learned how to publish a Move package; and in this section, we will learn how to call into functions defined in this package. As a result of publishing a package, we obtained the new package object ID (<PACKAGE_ID>) and ID of the Forge object (<FORGE_ID>) that can be used to create swords and transfer them to other players.

Let’s assume that the placeholder for the address of the player to receive a sword is <PLAYER_ADDRESS>. If you don’t know any address other than your own, you can create one using the following client command and use it whenever you see the <PLAYER_ADDRESS> placeholder:

$ sui client new-address

Which yields output resembling:

Created new keypair for address : 2D32ED71381BEF7F3D8C57B48DF82123593672AA

In order to create a sword and transfer it to another player, we use the following command to call the sword_create function in the M1 module of the package we previously published.

Important: Note placeholders on the command line and formatting of function parameters as it is important to follow the same pattern.

Now run:

$ sui client call --function sword_create --module M1 --package 0x<PACKAGE_ID> --args \"0x<FORGE_ID>\" 42 7 \"0x<PLAYER_ADDRESS>\" --gas-budget 30000

And receive output like:

Go to the Sui Explorer to observe a newly created object (ID 2E34983D59E9FC5310CFBAA953D2188E6A84FD21, in this example). You should see a sword object created with Magic property of 42 and Strength property of 7 and transferred to the new owner.

As above, replace the object ID in the Explorer link with the object ID of the created object you observed in your own command output, appended to: https://explorer.devnet.sui.io/objects/

This concludes the Sui Devnet setup and testing instructions. Revisit this page and re-install the binaries regularly to witness and help Sui grow!
