no signing if gas costs are zero with Metamask

[planichttm]

Describe the Feature

Hi there,
I am not sure if this is more a Metamask Feature Request or for ether.js

I do use ether.js for my project/game and I do have an issue with dozens of signing activities since it is a game and many actions have to be signed. Since I plan it with IOTA as DLT there are no gas fees and the signing is obsolete imo.

Is there a chance to avoid those signing actions or have the possibility to auto sign all that costs no gas? Or is this a Metamask feature request? My dirty workaround would be to have a separate backend and the client sends his transactions to the backend and then the backend would do the job with the Wallet signer so the client does not have to sign it. But this would then be less decentralized and then I would to have some kind of identity provider for the communication between client and backend and I really would like to avoid this workaround

Thanks in advance and regards
Martin

If you are mentioning a popup for signing, then that's coming from Metamask. You can have a temporary wallet created for the user (using Wallet class) for the game and store the wallet credentials in the browser (since no funds it shouldn't be a problem), so signing can be triggered in user's browser automatically and doesn't need the user to click a button. This kind of thing is also done in Dark Forest game which involves signing transactions all the time.

thank you for your quick reply
unfortunately with a temporary wallet on the client site I would lose the context to the users address that would like to receive token and NFT.

my smart contract functions would lose all necessary checks for preventing fraud. the wallet would then be the sender and therefore the specific address would needs to be a parameter in the function. Everyone could then call functions and put any address into it

What I am missing here?

And yes I mean the popup for signing.

Any idea or should I create something in the Metamask github?

Thank you very much

If you really need to use the user's long-term wallet (instead of a temp wallet), you may explore reducing the signatures by combining things. Alternatively, you may discuss in Metamask GitHub as an option to ask for multiple signatures in one go or something (this might not go through and can take time for discussions).

Just to mention, the game Dark Forest also provided NFTs to the top performers and they had to withdraw them to that temporary wallet (it's stored in the browser). The users can then move the NFT stuff to their permanent wallet later.
