If you're using VSCode, we recommend installing the Sway extension .
Additionally for this guide, ensure you're using Node.js/npm version 18.18.2 || ^20.0.0.
You can check your Node.js version with:
node -v Start with a new empty folder and name it multisig-predicate.
mkdir multisig-predicate Go into the multisig-predicate folder:
cd multisig-predicate Within your terminal start by creating a new sway project called predicate:
forc new --predicate predicateTip: Notice the
--predicateflag, which tellsforcthat you want to create a project based on a predicate, rather than the default contract program type.
Your project structure generated from the forc command should like this:
tree predicatepredicate
├── Forc.toml
└── src
└── main.sw
1 directory, 2 filesMove into your predicate folder:
cd predicate In VSCode, navigate to the src folder within the predicate folder, where you will find a file named main.sw. This is the file where your Sway predicate will be written.
