@v @gt It's interesting that Farcaster wallets leave no trace on Farcaster. There is no way to tell which wallet I used to approve signers. (Right? Or am I missing something?) 

I think future versions of app keys, should include some way for the wallet to leave a trace. Obv use is Farcaster Connect (knowing which wallets a user used in the past), but there may be other uses, we have not thought of, too.

So, how can you tell which wallet I used to generate the signer I approved today (real case)? I don't think you can (the answer is fario).

And there's no way to enforce it, but it might be a good idea for the wallet to include an id or something if they like, in the tx.

Hmm... I see what you mean. But that's not the same as the app used. It's easy to tell for Warpcast, because it uses a specific flow, and (I guess) a specific address to fund the transactions. But not in general.

you can check the chain and reconstruct this from events, but it's not easy to read:

If you add a key directly with add(), you can work back from the Add event to the transaction to the sender. 
If you did it with addFor(), you can work back from the Add event to the signature, which recovers to the approving wallet. 

But you'd want to index all this to use it.

No, no, that's not what I mean. 

For any signer right now, you can tell the app and the fid. But you can;t tell which Farcaster wallet I used to create it. Did I use Warpcast? Fario-signers? Neynar? Something else? It would make some use cases simpler, if you knew that I usually use Warpcast as my Farcaster wallet.

1. Signers are onchain

2. Sign in with Farcaster / Farcaster Connect -- think of this like Sign in with Google via OAuth. Do you want that publicly visible for everyone to see what websites you use?
