A place for developers to talk about building on Farcaster.

/dev

If I need to verify a user who is connecting to my mini-app that their fid I’m receiving in the context is legit,  what is the go to way of doing this these days on farcaster?

I’m seeing AuthKit but also signIn in the frame SDK?

Engineer @ Syndicate, prev: Rainbow, Foundation & Cloudflare /poetic-web, builds caststorage.com

technically the best way to do this is using sdk.actions.signIn from the frame sdk, which uses SIWF/AuthKit under the hood and you get the exact same response data back

Ok awesome and does this happen seamlessly or requires a click to trigger the sign flow

This is really good to know. Have you come across useful way to persist the auth state so api calls for users can retrieve specific data

you choose whenever you want to call sdk.actions.signIn and as soon as you call it the UX is:
- on web, a toast immediately pops up asking you to confirm SIWF on your phone & once you do you can proceed into the mini app
- on mobile, SIWF happens behind the scenes(eg. no manual approval button needed from the user) & so this basically happens instantly
