Solana: Setting up Web3 environment locally

Here is a step -by -step guide to set up a web3 environment locally on your Windows machine:

Prerequisites

• Node.js (14.x or higher) installed on your Windows machine

• A code editor or IDE of your choice (eg visual studio code, Intellij Idea)

• A local blockchain explorer (for example, inflow, metamask)

Step 1: Install and Web3 Wallet and Library

.

.

Step 2: Configure the electron in the windows

• Install Node.js on the official website if you have already done so.

• Download and install the Electron of [here] (

• Follow the installation instructions for your electron version.

Step 3: Install Web3.js and a local blockchain explorer **

• Run NPM Install Web3 on your terminal to install Web3.js.

• Install a local blockchain explorer, such as Infura or Metamask. For this example, we will use Inura.

Step 4: Set the local web3 environment

• Create a new folder for your project and browse it.

• Run NPM Init to create a package file.json.

.

• Initialize a new Ethereum wallet using infer.

Step 5: Configure Web3.js

• Create a new JavaScript file (for example,Web3.js) in the project folder.

• Import theWeb3library and start with the local blockchain explorer.

JavaScript

CONST Web3 = Requires (‘Web3’);

CONST INFUUCACLIENT = new web3 (new URL (‘wss: //mainnet.infura.io/v3/your_project_id’));

// Configure your Ethereum wallet

CONST WEB3 = NEW WEB3 (Infacliente);

`

Step 6: Write your first smart contract

• Create a new JavaScript file (for example, mycontract.js) to write your first smart contract.

• Import the Web3 library and start with the local blockchain explorer.

`JavaScript

CONST Web3 = Requires (‘Web3’);

CONST INFUUCACLIENT = new web3 (new URL (‘wss: //mainnet.infura.io/v3/your_project_id’));

// Configure your Ethereum wallet

CONST WEB3 = NEW WEB3 (Infacliente);

`

Step 7: Compile and execute your smart contract

• Use a tool like Truffle to compile your smart contract.

• Run the contract compiled using the following command:

`Bash

NPX Truffle Run Mycontract.js

`

This will compile your contract, migrate to the Ethereum network and deploy it to the blockchain.

Example Code

Here is some example code for you to start:

`JavaScript

// Web3.js

CONST Web3 = Requires (‘Web3’);

CONST INFUUCACLIENT = new web3 (new URL (‘wss: //mainnet.infura.io/v3/your_project_id’));

// Configure your Ethereum wallet

CONST WEB3 = NEW WEB3 (Infacliente);

MODULE.EXPORTS = {

Contract: ‘Mycontract’,

Abbi: […], // defines the abbi of your contract

};

`

`JavaScript

// mycontract.js

CONST Web3 = Requires (‘Web3’);

Constt Infraclient = new web3 (new URL (‘wss: //mainnet.infura.io/v3/your_project_id’));

// Configure your Ethereum wallet

CONST WEB3 = NEW WEB3 (Infacliente);

MODULE.EXPORTS = {

From: ‘0xyour_address’,

To: ‘0xmycontadddress’,

Value: 100,

};

`

Tips and variations

• Use a different local blockchain explorer, such as metamask or polkadot.

• Use a different Ethereum wallet, such as metamask or metawallet.

• Compile your smart contract using a tool like truffle or webpack.

• Implant your smart network contract using a tool like truffles or remix.
