Solana: How to sign transaction message using new web3.js

Signature of transaction messages with the new web3.js library of Solana

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

Prerequisites

Before immersing yourself in the code, make sure you have:

• A CLI Solana installation set on the machine.

• The Solana Testnet or Mainnet account created and financed with Sol (Token Solana).

Step 1: Create a transaction message

First of all, create a transaction message using CREATETRANSATIONMESSEGE (). This function returns a transaction message object that contains transaction information:

`Javascript

Const TransactionMessage = pipe (

CreateTranseationMessage ({version: 0}),

);

This creates a parameter -free basic transaction message. You can customize it as needed.

Step 2: Set the payment of the transaction message commissions

To sign the transaction message, you need to set the "Fepayer" property:

Javascript

Const TX = pipe (

CreateTranseationMessage ({version: 0}),

(TX) =>

SettransotionMessagePePayer (TX, "Your Solana address");

);

Replace "your sole address" with your actual address of the Solana wallet.

Step 3: Sign the transaction message

To sign the transaction message, you can use thesigntransotionMessage () function:):

`Javascript

Const signature = waiting tx.sign ();

This returns an transaction message subject signed that includes transactions and the public key of the signatory. You have to pass this signature object as a topic to the desired implementation.

Example use cases

Here are some cases of example to sign a transaction message with web3.js of Solana:

• Distribution of the intelligent contract

  

  : When distributing an intelligent contract, it is possible to sign the transaction message using thesigntransotionMessage () () function to pass it as a topic to thedeployconttract ‘function.

`Javascript

Cons disploycontract = async () =>

Const TX = Pipe waiting (

CreateTranseationMessage ({version: 0}),

(TX) =>

SettransationMessageFepayer (TX, "Your Solana address")

);

Const signature = waiting tx.sign ();

// uses the signature to distribute the contract

2

Javascript

Const Queryhistory = Async () =>

Const TX = Pipe waiting (

CreateTranseationMessage ({version: 0}),

(TX) =>

SettransationMessageFepayer (TX, "Your Solana address")

);

Const signature = waiting tx.sign ();

// Use the transaction message signed for QUERY TRANSATION HEARTS

`

In summary, the signature of a transaction message with the web3.js of Solana allows you to add advanced features such as the management of commissions payers and the distribution of intelligent contracts. By following these steps, you can safely and efficiently report transactions on the Solana blockchain.
