To install the Fuel toolchain, you can use the fuelup-init script.
This will install forc, forc-client, forc-fmt, forc-lsp, forc-wallet as well as fuel-core in ~/.fuelup/bin.
curl https://install.fuel.network | shHaving problems? Visit the installation guide or post your question in our forum .
If you're using VSCode, we recommend installing the Sway extension .
To use the testnet toolchain, run the commands below:
fuelup self update
fuelup toolchain install testnet
fuelup default testnetOur frontend application will allow users to connect with a wallet, so you'll need to have a browser wallet installed.
The current Fuel Wallet release can only be used with the beta-5 network. To use the new testnet, you must use the Fuel Development Wallet .
You can get test funds for the testnet by visiting the Testnet Faucet .
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 fuel-project.
mkdir fuel-project Go into the fuel-project folder:
cd fuel-project Within your terminal start by creating a new Sway project called contract:
forc new contract Your project structure generated from the forc command should like this:
tree contractcontract
├── Forc.toml
└── src
└── main.sw
1 directory, 2 filesMove into your contract folder:
cd contract 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 except for the contract keyword.
contract; The first line of the file is specifically reserved to inform the compiler whether we are writing a contract, script, predicate, or library. To designate the file as a contract, use the contract keyword.
