Farcaster Devs

Warpcast now displays what client you sent a cast from

(For developers: It's the username of the FID of the signer of the cast. Supports ENS.)

Working on Farcaster and Warpcast. Longer thoughts at https://dwr.email

I don't know how helpful it is, maybe as a small way of advertising for clients.

Also there's a technical detail here, a signer that has its PK shared, can be used by anyone, so there's no 100/100 way to technically prove from which client the cast is sent.

For example I have a signer PK which the metadata was signed by firefly, but I can use that PK in any script then it would appear as firefly.

Generally the PK might not be shared, but again it's not possible 100/100 to guarantee a cast comes from a specific signer, just that the signer key used was signed by X FID.

So I guess the actually correct phrase is "Signed by - username" instead of "Sent from - username", signed by username also makes more sense because any FID can be a signer, and that FID by have a confusing name that is not a client, something like dwr, sds, gt, or any other such username.

Also you can create a signer from the same user that will send the cast.
