Solana: How to get tx signature(s) when using send_and_confirm_transactions_in_parallel()
Here is an article on how to obtain event signatures when used sond_and_confimm_transaction_in_parallel () sorana:
Acquisition of event signatures for Send_and_confirm_transactions_in_Paralll ()
In his recent messages, he has successfully implemented the use of Send_and_confirm_transactions_in_Parall () TPU client. However, when you invite this function, it does not create events automatically for each event.
If you need to obtain the firm (s) of the event when you send and confirm the events one next to the other, you must ensure that the TPU client is correctly configured and that processes errors or exceptions correctly.
Send_and_confirm_transactions_in_parallel ()
Send_and_confirm_transactions_in_parallel ()It is an asynchronous function that sends multiple events simultaneously with thetpuclientapplication. Although this approach can be effective, it does not automatically produce event signatures. Instead, each event has its own signature to send and reinforce.
Solution: Obtain event signatures manually
To obtain the firms of the event manually, you have:
- Send each event separately usingtpuclient
.
- Wait for each event to confirm before the firm is believed.
- Keep or print signatures as necessary.
Here is an example of how you can implement this in Python:
Python
Solan.publickey impultkey
import time
Def get_signature (tx_id, accounts_Key):
Send an event using tpuclient and wait for confirming
Client = tpuclient ()
tx_resscar = client
[[
{"Id": tx_id, "account_Key": account_Key},
],],
Waiting time = 60
wait up to 1 minute before creating signature
In
If it is not tx_resses:
return anyone
Create the signing of the event
Signature = client.get_transaction_signature (tx_id)
Restore the firm created as a chain
Return Str (signature)
Example of use:
tx_id = "sum_tx_id"
ACCOUNS_KEY = "SOM_ACCOUT_KEY"
Signature = get_signature (tx_id, account_key)
Print (f "event firm {tx_id}: {signature}")
Tips and variations
- Be sure to deal with exceptions that can occur during event processing.
- If you have to create bulk signatures, consider using a loop to send events and wait confirmations before creating signatures.
- You can also usetpuclient.get_transaction_signures () ‘to request signatures created directly from the server.
Following these steps and tips, you should be able to obtain event signatures when using the `Send_and_confirm_transactions_in_parallel () in its application.
