Getting Logs and Internal Instructions from Raw Instructions on Solana Using Python

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

Why Raw Instruction Data is Difficult to Work With

Raw instruction data contains information about transactions that are executed on the blockchain. While it provides valuable insight into how transactions are used, it is not designed to be easily parsed and accessed by developers. The RPC method getTransaction can only retrieve the state of a transaction, not the raw instruction data.

Getting Logs

Logs contain metadata about each transaction, including its input instructions, output instructions, and associated logs. To retrieve logs, you can use the RPC method getTransactions 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 that shows how to get logs:

from solana.web3 import Web3

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

Get all transactions in 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 enumerate(logs):
print(f"Log {i+1}: {log}")

Getting Inner Instructions

An innerinstruction is a special type of instruction that contains the input and output instructions for a transaction. To get an innerinstruction, you need to know which transactions are executing.

Here is an example Python code snippet that shows how to get an inner instruction:

from solana.web3 import Web3

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

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

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

Get the inner instruction from the first transaction with an inner instruction
inner_instruction = transactions_with_inner instruction[0].transaction.inner_instruction
print(f"Transaction inner instruction {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 always stored as logs on the blockchain; that is a separate concept.

I hope this helps you get started with importing logs and inner instructions from raw instruction data into Solana using Python!
