I have a stupid ethereum question.
Without using a smart contract, I am wondering if this is possible:
I have two addresses and two keys - wallet A and wallet B - one containing eth, the other containing erc20. Is it possible to pay to send the erc20 from wallet B with the eth for gas from Wallet A to third party (wallet c) in a single transaction.

You can have a look at something called meta transactions. In theory that is possible but it's a rather complicated topic and I'm unsure what kind of service providers are available currently for that

im actually trying to do it on layer 2

that won't help you, I'm afraid
as you'll need to first enter the L2 and then exit the L2 - that's at least two transactions

depends totally on the architecture

basically a person wants to pay for tokens that exist on a vault, so they deposit funds to a web wallet, then i have both keys.
but the tokens are here and the funds are there
the dicey part is that someone else has the ability to withdraw from the web wallet containing the tokens (the person that put them there) so there is an impetus to do it all in one transaction
