Hi,
when I create a SafeAuth ERC-4337 account abstraction wallet for a web3auth user and they send a transaction, who pays the transaction fee for the transaction?
Does it come out of the web3auth wallet of the user, so that we would need to fund the web3auth wallet with gas tokens in order to be able to make transactions? Or is it possible to pay transaction fees with assets within the SafeAuth wallet? If yes, what assets are supported to pay transaction fees (on Polygon PoS in our case).

Thanks for your patience.

It is the Safe AA wallet that needs to be credited. Polygon is one of the supported networks with SafeAuth.

We have an offer for creating a Safeauth Project with us, you can read more here

You can schedule a call with our Business team at Calendly - Web3Auth to better understand your requirements and answer further questions.

Do I understand correctly that on Polygon for example the Safe AA needs to be credited with MATIC tokens to pay for tx fees? Other tokens are not supported to pay for tx fees?

Yes, that is correct. For Polygon Network, gas fees is paid in MATIC.

Do check this article about transaction fees with Safe

You can post on the Safe Dev Community regarding using other tokens for gas fees(if possible): Newest 'safe-core' Questions - Ethereum Stack Exchange
