Farcaster Devs

Neynar

We got a fair number of asks for two things:

1. Developer branded signers for SIWN - so it says "sent from [developer_brand]" instead of saying "sent from neynar"

2. Using SIWN inside mini apps

Both are solved now! 
- mini app developers can now use SIWN to get permissions without leaving the mini app to an external web page
- developers get their own branding

https://docs.neynar.com/docs/mini-app-authentication

In order to get the above benefits, the flow does require slightly more work than earlier (don't worry the earlier approach is still around if you need it). 

If you implemented SIWN previously, you don't have to many changes as a result of this. What you have will continue to work. If you're building new, there's more functionality available now. 

h/t @shreyas-chorge for the work and reach out with any feedback 🪐

We've made managing and using @farcaster signers quite simple, but requesting permissions for signers is still a complicated UX to build. 

We'd seen the hard work @ampsfun, @dashapp, and others had put in to get a system for sign-in + signer approval going within their mini app, and decided to simplify it to the point where it's as simple as a component.

It's secure - the signer identifier and API key never touch the client.

It'll work across 
1. Farcaster - iOS & Android apps + desktop web.
2. Web app - desktop & mobile. Yes, it works outside the mini app context as well.
3. @coinbasewallet - iOS and Android apps coming as soon as they build the signer approval flows. cc @aneri.base.eth @dylsteck.eth :)

these apps need to call sdk.actions.close after the openURL the deeplink, because the farcaster connect signer requestor opens behind the app

On Farcaster this happens? Mobile or PC?

I haven't had any reports of this. I've observed openUrl redirecting to the  browser outside of FC which then redirects back to FC approval page. 

Do you have a video? That would be helpful!

android. showed a QR code, but the deeplink opened behind the mini app, so had to close the mini app

i think this is on farcaster end though, the signed key deeplink doesnt behave like other deeplinks that would minimize the mini app

also weird behavior between Android and ios, have found farcaster:// to work best and /~/ routes to sometimes work on one but not the other

will send a vid when i can

ah ok I see. is this right?

- click create signer (or whatever prompts the signer flow)
- redirected to browser via signer link
- browser redirects back to FC via deeplink
- when you land back on FC the signer approval isn't visible because it's covered by mini app

exactly...some recent change it started happening or maybe when the domains switch idk

minor inconvenience to ux, ill send some screenshots

@compusophy we went though the pain to resolve the "connect screen opens behind mini app" in the solution we implemented above. 

Check out these lines of code, there's another deeplink URL format that doesn't encounter this bug. Hope this helps!

compusophy signer is a simple relay mini app for getting signers

a standalone signer "module", so you can build new signer-required apps without having to recreate the signer getting logic

when your app needs a user's signer, you can simply use sdk.actions.openMiniapp(compusophy signer)
 
this launches the compusophy signer mini app, which will automatically generate and open the signer deeplink. upon completion, the user is redirected back to the compusophy signer app and finally bounced back to your initial referring app

of course im not suggesting that app devs rely on me for managing their user's signers. more of offering this model as a solution to abstract out this complexity into a reusable component

the app itself is headless and has no ui, just handles everything under the hood and redirects. signers are stored under the key of their connected wallet

repo will be "open source ofc" and might even make this more meta, a mini app to launch a signer handler...though this involves users creating a new account to use as the app fid of their signer handler...thus unique branding and isolated handling that you own

dont really want to go the route of managing signers for devs

awesome! that's really good to know

i turned the signer getter logic into its own mini app auth relay, so if i need a user's signer i just launch this mini app, instead of building it into every project

Neat! How do I try the flow? Is it implemented in an existing mini app I can try?
