Here is an article on how to parse TransactionInstruction in the new Web3.js:
Parsing Transactions and Instructions with the New Web3.js
After the latest update, the Solana library @solana-program/compute-budget has been moved to a separate module. To work with this new API, you will need to make sure you have the correct version of Web3.js installed.
To parse transactions and instructions in the new Web3.js, you can use the following code sample:
const web3 = require('web3');
const TransactionInstruction = require('@solana-program/compute-budget').TransactionInstruction;
// Create a new Web3 instance
const web3 = new web3.Web3(new // Change your main network URL
// Define the transaction instruction to parse
const computeBudgetTransaction = TransactionInstruction.create(
{
accounts: [
{
pubkey: 'compute-budget',
key: '0x000000000000000000000000000000000000000000000000001', // Change your application ID
type: 'Application Instruction',
},
{ pubkey: 'get_account_data', key: '0x0 // Parse the transaction instruction
const parsedTransaction = web3.eth.getTransaction({
data: computeBudgetTransaction,
});
console.log(parsedTransaction);
In this example, we create a new TransactionInstruction object using the `create'' method. We then define the accounts and instructionId properties that correspond to the application ID, the address of the get_account_data instruction, and the transaction ID.
Finally, we use theeth.getTransaction'' function to parse the transaction data from the underlying network API.
Note: Make sure to replace thecompute-budget'' application ID and the`get_account_data” instruction address with your actual values. Also, be aware that parsing transactions may reveal sensitive information about the inner workings of your application.
Use case examples:
- To parse the ComputeBudget instruction in Solana Explorer, you can use this code example as a starting point.
- You can also add error handling to catch any parsing errors or invalid transaction data.
- When working with new versions of Web3.js, be sure to update your dependencies and rebuild your project using “npm install” or “yarn install”.
I hope this helps! Let me know if you have any questions or need further assistance.
