Solana: How to make a copy of a transaction from a parsed transaction in Solana

Here’s an article on how to make a copy of a transaction from a parsed transaction in Solana:

Creating a Copy of a Transaction with Parsed Data in Solana

In Solana, transactions are parsed into data structures that can be manipulated and used for further processing. While compiled transactions can provide valuable insights into the state of a contract at a given point in time, they may not always reflect the current state of an account or the relationships between accounts. To create a copy of a transaction with parsed data, we will use the parsedTransaction.copy() method.

Prerequisites

Before we begin, make sure you have installed the required dependencies:

npm install @solana/web3.js

You also need to set up your Solana cluster and create a wallet. For this example, let’s assume we have a working cluster and a wallet initialized with a public key.

Parsing a Transaction

To parse a transaction, you can use the web3 library or the @solana/web3 SDK directly:

const web3 = new Web3(new Web3.providers.HttpProvider('


const transactionId = 'your-transaction-id';

const parsedTransaction = await web3.eth.getTransaction(transactionId, { blockNumber: 1 });

Creating a Copy of the Transaction

To create a copy of the transaction with parsed data, you can use the parsedTransaction.copy() method:

const copiedTransaction = await parsedTransaction.copy();

This will return a new parsed transaction that includes all the same fields as the original transaction.

Using the Copied Transaction for Further Processing

Once you have created a copy of the transaction with parsed data, you can use it to further process the account state or the relationship between accounts. For example:

const account = copiedTransaction.data.account;

// Get the new account state

console.log(account.state);


// Get the relationships between accounts

const relations = copiedTransaction.data.relations;

console.log(relations);

Important Notes

• The staticAccountKeys field is a requirement for creating a copy of a transaction with parsed data. This field represents the keys that are guaranteed to be present in the account state at a given point in time.

• The parsedTransaction.copy() method will only include fields that match the static account keys.

• If you need to create a new transaction, use the web3.eth.getTransaction method instead.

By following these steps, you should be able to create a copy of a transaction with parsed data from your Solana cluster. This can be useful for further processing or analysis of the account state and relationships between accounts.
