I have started work on an iOS native wallet for Grin. The idea is that I launch it as a testnet wallet to begin with, to allow me to bypass the cryptocurrency restrictions that Apple enforces on individual accounts. Once mature and fully audited, it can be launched as a mainnet app via a company or organisation. I look forward to hearing feedback in terms of functionality and behaviour. At this stage, the possibilities are pretty endless, so be creative. I have experimented with a payment wheel and shortcut buttons and I’m open to other ideas. I would certainly like to explore NFC on Android. iOS may be more of a challenge but the multi-peer connectivity is a good start. I think I still need to add HTTP addresses and QR code scanning whilst trying to avoid the UX getting crowded. The goal is to keep it usable by a wide audience.

Common restrictions are: unability to launch bridge for Tor (Apple limits memory usage for Network Extensions at 50Mb: [“Use Direct Connection” Always be 5% · Issue #94 · guardianproject/orbot-apple · GitHub](https://github.com/guardianproject/orbot-apple/issues/94#issuecomment-2395047362)) and LLC to publish the app. ---

Nice design! I particularly like the turning wheel to display the relative amount/total you are sending. Also being able to send via locally found devices is pretty cool. Perhaps to allow locally sending with Android add a QR button for the slate-pack and a read QR button for receiving. ---

Thanks. Yes I added the QR code generating and reading this morning lol. ![IMG_9750](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/2X/e/e2360bffcade1ae4b15abdb7ebc95998e79d6a12.png) ![IMG_9751](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/2X/4/4a1b2947dc235e7149c68b358b7d52a21d39663f.png) ---

Slatepack response is very big and can be hard to read for some cameras, check if Animated QR with UR resources can be added ([GitHub - BlockchainCommons/URKit: UR (Uniform Resources) reference framework for Swift · GitHub](https://github.com/blockchaincommons/URKit)) (also used by Blockstream’s Jade [https://help.blockstream.com/hc/en-us/articles/20347921365785-Send-air-gapped-Bitcoin-transactions-via-QR](https://help.blockstream.com/hc/en-us/articles/20347921365785-Send-air-gapped-Bitcoin-transactions-via-QR)) ---

This is awesome! Maybe you could take this in the [Venmo/Cashapp product planning](https://forum.grin.mw/t/venmo-cashapp-product-planning/9714) direction since it’s pretty open ended? I think people just expect and want something very very close to cash app these days. If we don’t have contacts and messages (and history with notes) built in to the app via a messaging protocol like chatmail, then I think users at least need something more than a plain slatepack text. Maybe wrap the slatepack in an app URI so tapping the slate auto opens your wallet and fills in fields with the slatepack text automatically? I think @ardocrat favors the file route because the slatepack is so very long though. It’s just that files are kinda spooky to people I think. So we sort of end up back thinking about a messaging protocol again. ---

Oh I guess Apple prefers developers using [Universal Links](https://developer.apple.com/library/archive/documentation/General/Conceptual/AppSearch/UniversalLinks.html) now instead of raw URIs. So like [https://gri.mw](https://gri.mw) instead of grin:// because the latter can be hijacked by malicious apps easier. Does Grim use a universal link for slatepack sending now? ---

After many late nights and early mornings, I have an important update to share. The following is a demo video of an alpha release of the Grin iOS testnet wallet. Source code to follow shortly. I’m currently in the process of publishing it in the App Store for direct download also. I’m approaching it from the angle that this version is for educational and research purposes so I am hoping that the cryptocurrency restrictions on individual accounts won’t apply. Fingers crossed on that. I’ll keep you updated on the progress.

The [source code](https://github.com/waynegeorge/grin-wallet-ios) is now public for anybody who wants to build and test. The FFI library is included so all you need is a Apple Silicon Mac with Xcode installed. ---

sound great! your wallet will connect to external node or can run local pruned node inside the app? ---

It would connect to an external node. Ideally one that you’d run yourself. Even if indefinite app background refresh was allowed on iOS, it’d likely drain the battery pretty quickly. ---

After a long delay, the App Store submission decision came through today with a decision of rejection. Their response follows below. In summary, they’ve essentially said that a testnet app is not suitable for the App Store and then if it was a mainnet app, it’d need to be submitted via an organisation as we know. I’m not sure about the second matter as I didn’t include the word “iOS” in the submission name. Nevertheless, the app can still be submitted via TestFlight. The App Store submission at this stage was an attempt to make it super accessible. I’m happy to discuss next steps in the meeting tomorrow.

Or you can work around by another name like grin chat? nickname based on grin address, able to create group chat,… connection to external nodes. interactive payment by slatepack only. remove all text related to crypto. ---

Why not call it iGrin or something similar, they would probably not accept it as name though​😜.
