I am trying to work with Solana in Python and I am trying to send an SPL token.

The transaction successfully sends & I can see logger logging the HTTP request, however, I can’t get the response with the signature ID.

This is my code:

transfer_spl_token:
    # Initialize Solana client
    client = Client(endpoint=SOLANA_ENDPOINT, commitment="processed")

    # Create transaction
    transaction = Transaction()

    # Get the associated token account address for the destination
    associated_token_address = get_associated_token_address(dest_pubkey, mint_pubkey)
    
    # Get our associated token account address for the source
    source_associated_token_address = get_associated_token_address(source_pubkey, mint_pubkey)
    
    logger.info(f"Source Associated Token Address: {source_associated_token_address}")
    logger.info(f"Destination Associated Token Address: {associated_token_address}")

    # Check if the associated token account exists
    response = client.get_account_info(associated_token_address)
    if response.value is None:
        # Create associated token account instruction if it doesn't exist
        create_ata_instruction = create_associated_token_account(
            payer=source_pubkey,
            owner=dest_pubkey,
            mint=mint_pubkey
        )
        transaction.add(create_ata_instruction)

    # Convert amount to smallest units
    transfer_amount = int(amount * (10 ** decimals))
    logger.info(f"Transfer amount in smallest units: {transfer_amount}")

    # Add the token transfer instruction
    transaction.add(
        transfer_checked(
            TransferCheckedParams(
                program_id=TOKEN_PROGRAM_ID,
                source=source_associated_token_address,
                mint=mint_pubkey,
                dest=associated_token_address,
                owner=source_keypair.pubkey(),
                amount=transfer_amount,
                decimals=decimals
            )
        )
    )
    
    # Send transaction
    response = client.send_transaction(transaction, source_keypair, opts=TxOpts(skip_confirmation=False, preflight_commitment="processed"))
    logger.info(response)

I’m calling this function here:

async def confirm_buy:
    # Transfer SPL token
    signature = transfer_spl_token(deposit_address, user_address, token_amount, privkey, mint_address)
    logger.info(signature)

This is what I see in my logger:

- httpx - INFO - HTTP Request: POST https://api.mainnet-beta.solana.com "HTTP/1.1 200 OK"

I am new to Solana programming and not too sure what’s going on. Do I need to sign the transaction before sending it (so I have the txn ID already)?

I tried changing the commitment/pre-flight commitment.

I tried making the function async

I can’t get the response from send_transaction()

I was expecting to get signature
