Deploying a contract on StarkNet Testnet2(Goerli 2) using Protostar

In this tutorial, we are going to deploy a contract in Tesnet2 using the Protostar from SwMansion.

We should already have Protostar installed. In my case, I have version 0.8.1. It is the latest version as of today.

If you do not have Protostar installed, you can do it here.

We will use the template provided by Protostar to make the tutorial. In it there is a contract, where you can obtain and increase the balance. To generate it we must execute the command

>>> protostar init
project directory name: hello_world_testnet2

We have to modify the configuration file protostar.toml We must add the following profile pointing to Testnet2.

[profile.testnet2.project]
gateway-url="https://alpha4-2.starknet.io"
chain-id=1536727068981429685321

The file would look like this protostar.toml

We are going to build the project by executing the following command

>>> protostar build

We are ready to deploy to Tesnet2 by executing the following command

>>> protostar -p testnet2 deploy ./build/main.json

Displays the Contract Address and the Transaction hash.

Contract address: 0x00427baaa71a7cb7e61860357a6045afd6a33ce27e5dd64e61f807ae28dc103f
Transaction hash: 0x041087cbdfa5cf53f53bbd52db3ad2f49579cde545397399500c3c9eb90ba881

Let’s go to the StarkScan website and we can see the status of the transaction.

Once the transaction is completed, we access our newly displayed contract.

We already have our contract deployed in Testnet2!!!
