Use ETH instead of STRK as gas

[azamtim]

Hi all
I'm using folowing function to transfer tokens from one wallet to another:
invocation = contract.functions["transfer"].invoke_v3_sync( recipient=parse_address(destination_wallet), amount=balance, auto_estimate=True )

However i get the message:
FAIL: Client failed with code 55. Message: Account validation failed. Data: perform_validations call failed; failure reason: TransactionFailureReason(code='native_blockifier.PyTransactionPreValidationError', error_message='TransactionFeeError(L1GasBoundsExceedBalance { max_amount: 29, max_price: 46018155035322, balance_low: StarkFelt("0x0000000000000000000000000000000000000000000000000000000000000000"), balance_high: StarkFelt("0x0000000000000000000000000000000000000000000000000000000000000000") })').

As I found out it tries to use STRK as gas, which parameter should i use in the function to make it using ETH as a gas

thanks

Hi @azamtim
For transaction fees in ETH, you should use invoke_v1. Please note that all v3 transactions are using STRK as their fee token.

Let us know if you have any other questions
