Hey there guys,more than 3 month ago I made a tutorial about deploying Smart Contract on Fuel,and I saw that some of you are facing issues with deploying it,so I decided to update the guide!In the coming weeks you’ll see more interesting content about Fuel!

So no more words!Let’s do this!

Open your Terminal in Ubuntu or Mac (Windows is no officially supported for now)

sudo apt update && sudo apt upgrade -y

sudo apt-get install git-all

Press Y

Now lets install curl

sudo apt-get install curl

As Sway language was inspired by Rust,we also need to install Rust toolchain

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Press 1 to process default installationThen

source "$HOME/.cargo/env"

After that, we need to remove old files

cd $home && rm -rf .fuel && rm -rf .forc && rm -rf .fuelup && rm -rf fuel-project

And then,install Fuel Toolchain

curl --proto '=https' --tlsv1.2 -sSf https://install.fuel.network/fuelup-init.sh | sh

Press Y

(btw if you are insterested I have a guide how to install Fuel Toolchain)

Close and open your terminal again,so the toolchain will be available in your shell

Just paste this commands 1 by 1.

fuelup self update

fuelup default beta-4

You can check your fuelup version by just typing

fuelup --version

Create folder

mkdir fuel-project

Then move into it

cd fuel-project

Then we create a contract project using forc:

forc new counter-contract

Then we need to edit out main.sw file (we will make it simple with just nano,you can use VS code if you like)

nano counter-contract/src/main.sw

So now delete everything that is inside the file

And replace with this:

contract;
 
storage {
    counter: u64 = 0,
}
 
abi Counter {
    #[storage(read, write)]
    fn increment();
 
    #[storage(read)]
    fn count() -> u64;
}
 
impl Counter for Contract {
    #[storage(read)]
    fn count() -> u64 {
        storage.counter.read()
    }
 
    #[storage(read, write)]
    fn increment() {
        let incremented = storage.counter.read() + 1;
        storage.counter.write(incremented);
    }
}

Every Sway file must start with a declaration of what type of program the file contains; here, we've declared that this file is a contract.In our case as you can see this is contract;

Once you’ve done it:

Press Ctrl + X

Then Y

Then Enter

Move to the folder of your created project

cd counter-contract

Now it’s time to build your contract

I’ll just leave you a link to the official guide - where you can check out how to test your contract and how to check out thee view of your project

• If you already have a fuel-wallet(like in my case - btw you can set up it here):

Just write that command

forc-wallet import

You’ll be asked to write 12 words - your seed and create a password to protect your wallet.

Then write

forc wallet account new

And one more time you’ll be asked to write a password that you’ve created.

• If you don’t have an account:

You can create a new wallet with the command below:

forc wallet new

Create a password to protect your wallet and make sure to save your seed.

Next, create a new wallet account with:

forc wallet account new

By that command you can check list of your wallets:

forc wallet accounts

As you can see I only have 1 account with that address

To deploy your contract on the network - you need some Test Eth.You can faucet it here.

And now it’s finally time to deploy your contract on the Fuel Network

forc deploy --testnet

You’ll be asked to enter your password again

Once you’ve entered a password,you’ll see your accounts(in my case there is only 1 account - its number is 0 )

Select number of your account and then type y

You can see your Contract ID - which you need to save here as we will need it in the next steps!But I want to congratulate you - you’ve deployed your first contract on Beta-4.

You can see your contract in the block explorer here (if it doesn’t appear - don’t worry,explorer doesn’t show most of the transactions right now but the team I’m sure is working on it!

Anyway don’t forget to tweet that you’ve built a smart-contract on Fuel,tagging @fuel_network
