Icon LinkPrerequisites

Before diving into any Sway code, ensure you have installed the following dependencies.

Start by installing the Fuel toolchain Icon Link.

Install the beta-4 toolchain distribution and set it as your default with:

$ fuelup toolchain install beta-4
$ fuelup default beta-4

You can check to see the current toolchain version installed by running the following:

$ fuelup show

Next, add the Sway extension Icon Link to your VS Code.

If you want to be able to run tests in Rust, install the Rust toolchain Icon Link as well.

This example uses the beta-4 toolchain, which is version 0.45.0 of forc

Within your terminal start by creating a new folder called sway-store, and making a new contract called sway-store-contract.

$ forc new sway-store
$ cd sway-store

Open up the contract folder in VSCode, and inside the src folder you should see a file called main.sw. This is where you will write your Sway contract.

Since we're creating a brand new contract you can delete everything in this file.
