Get Logs and Internal Instructions from Raw Solana Instruction Data Using Python

Solana is a fast and scalable blockchain platform that allows developers to build smart contracts with low latency. However, working with raw instruction data can be difficult to get logs and internal instructions. In this article, we will explore various ways to extract these values ​​from a transaction in Solana.

Why Raw Instruction Data is Difficult to Use

Raw instruction data contains information about the operations performed on the blockchain. While it provides valuable information about how transactions are used, it is not designed to be easily parsed and viewed by developers. The RPC getTransaction method can only retrieve the transaction status, not the raw instruction data.

Get Logs

Logs contain metadata about each transaction, including its input instructions, output instructions, and associated logs. To retrieve logs, you can use the RPC “getTransactions” method to retrieve all transactions on the blockchain, and then filter the results by a specified account or transaction ID.

Here is an example Python code snippet showing how to retrieve logs:

from solana.web3 import Web3

Initialize the Solana web3 client
w3 = Web3(Web3.HTTPProvider ("

Retrieve all transactions on the blockchain.
all_transactions = w3.get_account_info(
"Solana-key", 
"user"
).result[0].transactions
logs = [tx.transaction.log for tx in all_transactions]

Print logs (optional)
i, log numerate(logs):
print(f"Log {i+1}: {log}")

Get Internal Statements

An internal statement is a special type of statement that contains the input and output instructions for a transaction. To get an internal statement, you need to know what transactions are being executed.

Here is an example Python code snippet that shows how to get an internal statement:

from solana.web3 import Web3

Initialize the Solana web3 client
w3 = Web3 (Web3.HTTPProvider ("

Get all transactions on the blockchain.
all_transactions = w3.get_account_info(
"Solana-key", 
"user"
).result[0].transactions
transaction_index = 0
and transaction_index < len(all_transactions):

Filter transactions by account ID or transaction ID
transfers_with_innerinstruction = [
tx for tx in all_transactions if tx.transaction_id == 'some_transaction_id'
]

Get the inner instruction of the first transaction with the inner instruction
inner_instruction = transactions_with_innerinstruction[0].transaction.inner_instruction
print(f"Inner instruction of transaction {all_transactions[transaction_index].transaction_id}:")
print (inner_instruction)
transaction_index += 1

Note: The examples above assume that you have the necessary permissions and credentials to access the Solana blockchain. Also, keep in mind that raw instruction data is not necessarily stored as logs on the blockchain; that is a separate concept.

I hope this helps you get started reading logs and internal instructions from raw Solana instruction data using Python!
