Create a Dev3 App

Dev3 is a low-code development framework and process automation environment for blockchain applications. The current implementation works on EVM, with Rust support for NEAR blockchain coming soon.

Create your first Dev3 workspace

Let's make your first workspace with the Dev3 Dashboard!

Create a new workspace

In order to build applications on Dev3, you need to create a new Dev3 workspace. A Dev3 workspace is where you build your Web3 application(s). It contains the deployed contracts, snapshots, workflows, third party integrations, SDK access and everything else you need to build and maintain your Web3 application.
In order to create a new workspace, please visit https://app.dev3.sh
Once you get to the Home page, first you will need to log-in into the application. You have three different choices for log-in
Options for logging in!
  1. 1.
    Email - Dev3 is using Magic as a provider for custodial wallet solutions. By selecting "Email", you accept that you are using Magic to connect and interact with blockchain!
  2. 2.
    MetaMask - By choosing MetaMask, you will be interacting with your browser wallet which is most often MetaMask. If you don't see this option, you must install MetaMask from the extension store for your browser.
  3. 3.
    WalletConnect - You can use wallet connect if you have a web3 compliant mobile wallet, such as MetaMask or Trust. To see the full list of supported wallets, click on the WalletConnect button and explore the options.
Once you have successfully logged in or connected your wallet, make sure the selected network is "Mumbai Testnet" and click on the New Mumbai Testnet Workspace button:
Creating new workspace on Mumbai Testnet.
At this point, you should be on the "New Workspace" screen, which looks like the screenshot below. If you don't see the yellow warning, you can skip the next step. If you see it, follow the next step to fund your wallet with gas tokens. Gas tokens are used on blockchain to pay for transaction execution. However, since we are using a testnet - you will get the gas tokens for free!
Workspace creation step.
Getting testnet gas tokens
First copy your connected wallet address by clicking the "copy" button next to your wallet address in the top right corner.
Copy wallet address button.
Then visit the following link https://faucet.polygon.technology/​
Once there, paste your wallet address into the "Wallet address" field and click the Submit button, as per the screenshot below.
Pasting wallet address and submitting the faucet request for test tokens.
After completing this, return to the Dev3 Workspace Creation step and refresh the screen until the yellow warning disappears.
Creating the workspace
Fill out the workspace name and click "Create". It will take some time to process the action, so please wait for the completion.

Once your workspace is successfully created, you will be redirected to the home screen where all your workspaces are listed, which should look like the screenshot below:
List of created workspaces on the Dev3 Platform.
Clicking on the "Open Workspace" button highlighted in the screenshot above, you will land on your main Dev3 Dashboard, where you can start building applications!
The workspace, when opened, looks like this:

Now you're ready to start building! 🚀 We've started releasing our series of guides explaining how to use the platform to cover some of the popular use cases. The first one in the list is:
