Is your feature request related to a problem? Please describe.
Looks Rare's UI does not support EIP1271. It makes the usage of smart contract wallets impossible for certain operations e.g making an offer.

Describe the solution you'd like
Support EIP1271, it is pretty simple.

Describe alternatives you've considered

Additional context

Is there an API endpoint for listing via EIP 1271? Doesn't have to be a UI

[rodrigoherrerai]

You just need to check if the address has code, if it does:

1. Call 'isValidSignature()' with the hash and the signature.

If it returns the magic value, then the signature is correct.

The problem with not supporting this, is that wallets like gnosis and argent are unusable.

[treasureseth]

I know how to make the contract work. But to list it, you still need an API endpoint. That was what I was referring to

[rodrigoherrerai]

I don't understand, what do you mean by "list it" ?

The checks and auth should be done from the UI.

[treasureseth]

Just by creating the contract, you won't create a listing. You need to pass on the signature to LooksRare so that they can save it to their database. That is done by either an API call or by the UI.

That's why I was asking if there's an API endpoint to list it
