Getting Logs and Internal Instructions from Raw Instruction Data in 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, retrieving logs and internal instructions can be a difficult task. In this article, we will look at different ways to extract these values ​​from a Solana transaction.

Why is it difficult to work with raw instruction data

Raw instruction data contains information about transactions that are executed on the blockchain. While it provides valuable information about transaction usage, it is not intended for simple analysis and developer access. 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 statements, output statements, and associated logs. To get the logs, you can use the RPC method “getTransactions” to retrieve all transactions on the blockchain and then filter the results by a specific account or transaction ID.

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

from solana.web3 import Web3





Solana web3 client initialization
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 Internal Instructions

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

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

from solana.web3 import Web3

Solana web3 client initialization
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; it is a separate concept.

I hope this helps you get started extracting logs and inner instructions from raw instruction data in Solana using Python!
