Getting Logs and Internal Instructions from Raw Instruction Data in Solana with 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 challenging. In this article, we will explore the 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 the transactions running on the blockchain. While it provides valuable information about how transactions are used, it is not designed to be easily parsed and accessed by developers. The getTransaction RPC method can only get the status of a transaction, but not the raw instruction data.

Getting Logs

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

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

from solana.web3 import Web3









Initialize a 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
logs = [tx.transaction.log for tx in all_transactions]

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

Get InnerInstruction

Innerinstruction is a special type of instruction that contains the input and output instructions of the transaction. To obtain internal instructions, you need to know which transactions are being executed.

Here is an example Python code snippet that demonstrates how to get innerinstruction:

from solana.web3 import Web3

Initialize a 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
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 innerinstruction of the first transaction with innerinstruction
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 records on the blockchain; it is a separate concept.

Hope this helps you get started with getting logs and inner instructions from raw instruction data in Solana using Python!
