execTransaction

execTransaction

Executes a Safe transaction to to with value (native currency) and pays gasPrice * gasLimit in gasToken token to refundReceiver.

⚠️

The fees are always transferred, even if the user transaction fails. This method doesn't perform any sanity check of the transaction, such as if the contract at to address has code or not. It is the responsibility of the caller to perform such checks.
