signing transaction messages with the new web library3.JS a Solana

Solana is a popular blockchain popular platform for its rapid and scalable processing of transactions. To add advanced features to your transactions such as signing messages, you will need to use the new web3.Js. In this article, we will guide you through the process of signing a transaction message using Web3.Js.

Premise

Before you sink into the code, make sure you have:

  • A SOLANA CLI installation configured on your car

2.

Step 1: Create a transaction message

First of all, create a transaction message using CreatetransctionMessage (). This feature returns a transaction message object containing transaction information:

`Javascript

consist transactionmessage = pipes (

CreatetransctionMessage ({version: 0}),

);

`

This creates a basic transaction message without parameters. You can customize it as needed.

Step 2: Set the tax payer for transaction messages

To sign the transaction message, you must set theFeepayer ‘property:

`Javascript

const tx = pipe (

CreatetransctionMessage ({version: 0}),

(tx) =>

SettransctionMessageFefeepayer (TX, “Your Solana Address”);

);

`

Replace the "Solana address" with your Solana wallet address.

Step 3: Sign transaction message

To sign the transaction message, you can use theSigntransionMessage ()

`Javascript

const -semnature = wait tx.sign ();

`

It returns a signed transaction message object that includes the transaction data and the signator's public key. You will have to pass this object "Signature as an argument for the desired implementation.

Example of use cases

Here are some examples of use cases for signing a transaction message with Web3.JS Solana:

  • Intelligent contract implementation : When you implement a smart contract, you can sign the transaction message using the SigntransionMessage () and transmit it as an argument for the deploycontract function.

`Javascript

CONST imploycontract = async () =>

const tx = wait for the pipe (

CreatetransctionMessage ({version: 0}),

(tx) =>

SettransctionMessagefeePayer (TX, “Your Solana” address)

);

const -semnature = wait tx.sign ();

// use the signature to implement the contract

`

  • The history of query transactions

    : When you interrogate the transaction history, you can pass the transaction message signed as an argument to the "Querytransctionhistory" function.

Javascript

Const queryhistory = async () =>

const tx = wait for the pipe (

CreatetransctionMessage ({version: 0}),

(tx) =>

SettransctionMessagefeePayer (TX, “Your Solana” address)

);

const -semnature = wait tx.sign ();

// use the transaction message signed for the history transactions history

“

In summary, the signing of a transaction message with the web3.JS library allows you to add advanced functions, such as managing tax payments and implementing smart contracts. By following these steps, you can safely and efficiently sign transactions on the solar blockchain.
