This is a bit of an advert, but I made a an iOS Bitcoin wallet that only supports Multisig (P2WSH) via QR signing. I made it for myself because I wanted it. It works great with Sparrow Wallet and SeedSigner. I named after the Eastern hellbender, North America's largest salamander. It’s still missing a few features I want, but it’s like 95% done. I feel like no one will ever use it except me. Even so, I was going to put it on the App Store but I’m not so sure now. I forgot Apple requires “cryptocurrency wallets” to be submitted by an organization/LLC. This would take me a decent amount of time and money on my end. All I really wanted was an easier way for me to install it on my own phone and share with others. I wish Apple allowed side loading so badly.

Anyway, if you have iOS and your interested in trying it out: https://testflight.apple.com/join/PuHVwJDJ%E2%80%A8 Repo: https://github.com/newtonick/hellbender-wallet
