Developer Call Q&A

What questions do you have?

We're planning to mix in questions live attendees and the top-rated replies to this cast (assuming they are developer focused).

Collectibles bug: When I tap a cast from the auction page and try to engage with it, I can’t

🚀 New Farcaster Wallet feature: Batched Transactions!

Our wallet now supports EIP-5792 `wallet_sendCalls`, a major upgrade that lets you batch multiple transactions into a single operation.
No more separate steps to approve and transact, you can now set allowance + execute in one go!

We provide same security guarantees with transaction scanning, the experience is just so much better. We still don't support atomic transactions or paymaster support, but are hopeful those will come soon with EIP-7702

Our wallet now supports batched transactions so you enable setting allowance + execute a transaction in one step for your users 🙌

📢 New Mini App feature: export full Mini App history

You can now export your full Mini App analytics history as a JSON file!

From your Mini App dashboard, you’ll now see a new dropdown option: “Download Extended Dataset” This lets you export your historical analytics in full.

We recommend loading the JSON file into a tool like Pandas or Claude to explore and visualize your data more easily.

As always, we love your feedback, let us know what you’d like to see next!

Our current mini app dev dashboard only displays the past 28 days and now you can export a file for full metrics history to better track

Thanks @codyb.eth and others for the feature request!

There's now a new art category for mini apps on the explore page! 

Thanks @pirosb3 for adding it and @cybershakti for the request! 

Congrats @stephancill @zeni.eth @chriscocreated @fxhash @miguelgarest.eth for being in the top 5 🔥

I make digital art that explores how we express ourselves together.

does farcaster not support inline audio player ?

Seeking feedback on Mini Apps devex

Any significant issues testing/using notifications for Farcaster Mini Apps?

Reach out, would love to hear your thoughts!

What do you want improved about Mini Apps?

any free hubs that allow write out there?

Curious: any out there that don't require an API key?

After updating the app, I no longer see actions under casts! Have they been removed or is there a UI bug? @v @deodad

For developers: Farcaster collectibles

1. Onchain stuff is on Base

2. Bids are USDC

3. To start, you need to use the Farcaster app + wallet to bid. And FID is required to bid.

4. Auction logic is offchain so we can iterate faster.

5. When auction ends, settlement of bids in onchain. Collectible gets created on onchain.

6. NFT is a single collection.

7. We're thinking about 1) NFT metadata 2) public APIs for auctions 3) other developer legos.

8. If collectibles is "working" (subjective, will take some time to figure this out), will figure out how to make more "protocolized" and easy for other clients that would want to add. Eventually, auction logic could also be onchain (after we're confident in the right configuration).

trying to implement sign in with farcaster for a project using cursor. this is what it said. is this a limitation?

"The authentication state not persisting on refresh is actually a common limitation with Farcaster Auth Kit. This is by design for security reasons - the authentication state is meant to be session-based."

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 :)

ns.com could use more social protocol devs these were mostly games and a couple friend/dating apps + a dao prototype interface
