Here is an article on how to parse TransactionInstruction
in the new Web3.js:
Parsing Transactions and Statements in the New Web3.js
Since our last update, the Solana library @solana-program/compute-budget
has been moved to a separate module. To work with this new API, you need to make sure you have the correct version of Web3.js installed.
You can use the following code example to parse transactions and statements in the new Web3.js:
const web3 = require('web3');
const TransactionInstruction = require('@solana-program/compute-budget').TransactionInstruction;
// Create a new Web3 instance
const web3 = new web3.Web3(new // Replace with your network URL
// Define the transaction statement for analysis
const computeBudgetTransaction = TransactionInstruction.create(
{
accounts: [
{
pubkey: 'compute-budget',
key: '0x00000000000000000000000000000000000000000000000000001', // Replace with program ID
type: 'ProgramInstruction',
},
{ pubkey: 'get_account_data', key: '0x0 // Parse the transaction statement
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 initialId properties that correspond to the program ID, the get_account_data instruction address, and the transaction ID.
Finally, we use eth.getTransaction
to parse the transaction data from the mainnet API.
Note:
Make sure to replace the compute-budget
program ID and get_account_data
statement address with actual values. Also, remember that parsing transactions can potentially reveal sensitive information about the inner workings of the program.
Usage Examples:
- If you want to parse the ComputeBudget statement 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 dependencies and rebuild the project using
npm install
oryarn install
.
