Here’s the state of the ethhers.js for connecting Metamask to the location of the Hallow Hardhat:

Council metamaski with place postchat -fells with ethers.js

At the time of dentralized adjacent (DAPP), which are sought for the sake of universities, such as the Metamask or the Postoviki Web3, their connection to the nicer hcals of Hardhat. In this state, we disperse, how to use ethers.js to reach this lir.

** Proto Ethers.js?

Ethers.js is an offical bibliote of JavaScript for the interactive with the blockchain ethereum. Web3.js and more second. Using ethers.js, you can easily connect the locomotor Hardhat node to the extraordinary services, not the work of the settling infrastructure or configurations.

Settings Local Half Hardhat

In front of us we are submerged in Metamask connecting that your local Hardhat node is right. Here’s the Shorteba Rams:

1

• Install a new project of the project and initiate it:

`Bash

Mkdir Metamask-Connection-PRIMER

CD Metamask-Connection-Example

NPX Truffle Init

`

3

`The focus

Pragma Polidy ^0.8,0;

MyContract Contract {

Uint256 Social shadows;

}

• Skampilly and unfold your counteract:

`Bash

Truffal compilation

Expanding the trufe

`

COLITING Metamaski with ethers.js

Now, when you have a locomotor Hardhat, let’s pull up Metamask with Ethers.js. We will use the library ethers.js for the midamask.

Submit the new file with the name Metamask-connection.js and add the following code:

`Javascript

Const ethers = require ('Ethers');

// Install the address and abi

Const Contractdaddress = '0x ...'; // Outline your contract

Const abi = [...]; // Out on abi your counteract

// Create a new copy of Etherers for your location Hardhat

Const Provider = New Ethers.Providers.httpprovider ('http: // localhost: 8545');

// Create a new copy of Koshka Ethers.js with Metamask Post

Const Swellet = New Ethers.Wallet (Posthar, '0x ...'); // replace the Metamask key

// Calve the copy of the counters

Const Contractinstince = New Ethers.Contract (Contracttadrress, Abi, Koshelek);

// Now you can use a counterating copy for mutilation with blockchain

Contractinstince.value.set (123);

Prime Upolizing

Here’s the primer that you can use the combination of Metamask to install values ​​on your counterattte:

`Javascript

Metamask-connection.js

Inspectorate that you have a file mycontract.sol in Tom Catalog, you can release the following function for the contract:

`Javascript

Setvalue = (Value) => {

Contractinstince.value.set (values);

}

The following is this step and dimensions, now you should have the opportunity to connect a huge sunshine!
