To create and save keyboard in Solan web3.js v2

introduction

In this article, we will show how to create a keyboard with @soana/web3.js library (V2) and save it as a payer for future use.

conditions

Before you start, make sure the following follows:

• Node.js (preferably the latest version)

• @Sorana/Web3.js Library (V2)

• Solana Clli Installation

Create a keyboard with web3.js v2

You can create these steps using the keyboard web3.js V2:

`Javascript

Import {GeneratePairsigner} ‘@soan/web3.js’;

Const Keypair = Wait GeneratePairsigner ();

`

In this example, we bring the GeneratePairsigner from@Sorana/web3.js and create a new keyboard.

Save keyboard to local storage mode

You save the created keyboard for local storage for future use as a payer You can edit the code as follows:

`Javascript

Import {GeneratePairsigner} ‘@soan/web3.js’;

Const Keypair = Wait GeneratePairsigner ();

Wait for a new promise (resolve => {

Const clayeypairtostorage = () => {

// You can use web3 implementation to interact with your wallet

// For example, depositing an event in Sorana -Blockchain:

// web3.frombuffer (web3.eth.ccounts.receivetigaddress) .Sendtransaction ({

// sender: Keypair.publickey,

// to: '

// Information: 'Transaction-Data'

//});

};

Clayeypairtostorage ();

solve();

});

In this example, we use the promise to save the keyboard in local storage mode. When you call clayeypairtostorage ', it urges the user's address and event information.

as a keyboard re -use payer

Once you have saved the keyboard to your local storage mode, you can re -use it as a payer by calling "Keypair.publickey" directly:

Javascript

Const Recipient Daddress = ‘Recipient Address’;

web3.frombuffer (web3.eth.ccounts.receivetigaddress) .sendtraSaction ({

Posted by: Keypair.publickey,

To: Recipient,

Information: ‘Transaction-Data’

});

`

Alternatively, you can use the web3 in interacting with your wallet:

`Javascript

Const web3 = new web3 (new URL (‘./ poate/to/web3.js’). Origin);

web3.frombuffer (web3.eth.ccounts.receivetigaddress) .sendtraSaction ({

Posted by: Keypair.publickey,

To: Recipient,

Information: ‘Transaction-Data’

});

`

Remember to replace .

In this article, we showed how to create a keyboard with Solana using the@soana/web3.js` library (V2) and save it as a payer for future use. By following these steps, you can re -use your keyboard in Sorana Blockchain.
