Install Thirdweb CLI

You can install the Thirdweb CLI globally on your machine using npm by running the following command.

npm i -g @thirdweb-dev/cli

Create a project

1. Start by creating a new project by running:

   npx thirdweb create contract

2. Input your preferences for the command line prompts, such like:

   ✔ What is your project named? … mantle-test
   ✔ What framework do you want to use? › Hardhat
   ✔ What will be the name of your new smart contract? … MyContract
   ✔ What type of contract do you want to start from? › Empty Contract

   Here we have chosen to use the hardhat framework and generated an empty contract project.

3. Place the contracts you want to deploy in the contracts folder, for example, let's deploy a Storage contract.

   // SPDX-License-Identifier: GPL-3.0
   
   pragma solidity >=0.8.2 <0.9.0;
   
   /**
   * @title Storage
   * @dev Store & retrieve value in a variable
   * @custom:dev-run-script ./scripts/deploy_with_ethers.ts
   */
   contract Storage {
   
       uint256 number;
   
       /**
       * @dev Store value in variable
       * @param num value to store
       */
       function store(uint256 num) public {
           number = num;
       }
   
       /**
       * @dev Return value
       * @return value of 'number'
       */
       function retrieve() public view returns (uint256){
           return number;
       }
   }

Deploy your contract

The command deploy allows you to deploy a smart contract to Mantle Network without configuring RPC URLs, exposing your private keys, writing scripts, and another additional setup such as verifying your contract.

1. To deploy your smart contract using deploy, navigate to the root directory of your project and run:

   npx thirdweb deploy

   Sample Outputs

   ✔ Detected project type: hardhat
   ✔ Compilation successful
   ✔ Processing contract: "Storage"
   ✔ Upload successful
   ✔ Open this link to deploy your contracts: https://thirdweb.com/contracts/deploy/QmPQJLQaEHVRD55hUSvkraSb74ZzBqwCcmFGGCXX5TLmx6

2. Open the link and connect your wallet, select the network you need to deploy, and click the Deploy Now button to complete the deployment!
