Here is an article on how to obtain transaction signatures when used Send_and_confirm_transactions_in_parallel () in Solana:
Obtain transaction signatures with Send_and_confirm_transactiCs_in_parallel ()
In his recent publications, he has successfully implemented Send_and_confirm_transactions_in_parallel () Using the TPU client. However, when it calls this function, it does not automatically generate transaction firms for each transaction in the lot.
If you need to obtain transaction signatures after sending and confirming the transactions in parallel, you will want to make sure your TPU client is configured correctly and that it is handling any error or exception correctly.
The problem with Send_And_confirm_transactions_in_parallel ()
Send_and_confirm_transactions_in_parallel () It is an asynchronous function that sends multiple transactions simultaneously using the tpuclient. While this approach can be efficient, it does not automatically generate transaction signatures. Instead, each transaction will have its own signature when sent and confirmed.
Solution: Get transaction signatures manually
To obtain transaction firms manually, you must:
- Send each transaction individually using the
tpuclient.
- Wait for each transaction to confirm before generating a firm.
- Store or print the firms generated as necessary.
Here is an example of how you can implement this in Python:
`Python
of Solana.publickey Import publickey
Import time
Def get_signature (tx_id, accounts_Key):
Send the transaction using tpuclient and wait to confirm
client = tpuclient ()
tx_resscar = client.send_and_confirm_transactiS_in_parallel (
[
{"id": tx_id, "account_Key": account_Key},
]
Waiting time = 60
wait up to 1 minute before generating a firm
)
If it is not tx_resses:
It does not return any
Generate the transaction firm
Signature = client.get_transaction_signature (tx_id)
Returns the firm generated as a chain
Return Str (signature)
Example use:
tx_id = "sum_tx_id"
ACCOUNS_KEY = "SOM_ACCOUT_KEY"
Signature = get_signature (tx_id, account_key)
print (f "transaction signature for {tx_id}: {signature}")
Tips and variations
- Be sure to handle any exception that may occur during transaction processing.
- If you need to generate bulk signatures, consider using a loop to send transactions and wait confirmations before generating signatures.
- You can also use thetpuclient.get_transaction_signature ()
method to recover the firms generated directly from the server.
Following these steps and tips, you should be able to obtain transaction signatures when you usesend_and_confirm_transactions_in_parallel ()` with its solena application.
