@haochizzle @nulliedge @RAILGUN_Project @Ledger @Trezor @Keycard_ Also @glgrau if I'm mistaken here and you can confirm the JC can do all our curve math then we get a quicker answer haha but it's not 'not possible' just need to use the card core crypto libs for some expensive math otherwise from my first 'go' at it it was nearly 30+mins

one of my biggest asks for @RAILGUN_Project has always been... hardware wallet support.
in about a week's worth of work, @_zy0nn prototyped zk proofs that sign from a @Ledger 🤯

@NeuralBateman @safe @Keycard_ It's indeed the feedback we usually get when one starts using shell. I think we could do a better job to convey how liberating and smooth the overall experience of using a hardware wallet becomes.
regarding safe, have you tried shell+ambire btw?
ambire mobile is coming soon

Indeed it's recommended to use a webcam with autofocus. Those fixed focus webcams lenses are set at hyperfocal distance which means they are in focus from 'one distance' to infinity.
If this 'one distance' is too far from the computer (e.g 50cm) when you put your QR in front of the camera, it's too close :(

Unless @Apple's decision to terminate @craigraw's Apple Developer account is reversed by June 30, all new installs of Sparrow will fail, and development on macOS will end. If you value Sparrow, a repost would help. @AppleSupport

My attempt to protect users from scam apps on the @AppStore has gotten my Apple Developer account flagged for termination - ironically, for "dishonest activity". Unless it's reversed by June 30, all new installs of Sparrow Wallet will fail, and development on macOS will end. The context: since 2023, more than a dozen fake "Sparrow" apps have appeared on the App Store, as recently as April this year. Users have contacted me after losing their savings, in some cases their life savings, to these impersonators. I'm the developer of the real Sparrow Wallet, a desktop app, and I hold the registered US trademarks for the name and logo. I have publicly warned @Apple and the community about these fake apps from early 2024, but they keep appearing. The app @Apple flagged was a placeholder that was never published. Its only purpose was to warn users that Sparrow is desktop-only and that other "Sparrow" apps aren't mine. This approach may have been misguided, but there was nothing dishonest about it. I'm confident this is an automated misclassification that Apple would reverse on review - but I may be terminated before a human ever looks at my appeal. The cost would fall on @Apple's own users: blocked installs and no updates for a tool people rely on, which opens the door for more fakes. If you value Sparrow, a repost would help. @AppleSupport

@web_oko It's different from AC but good enough for me. One key thing is that it's much cheaper and much easier to install ofc.

Best investment this year for my home
I read sales of these ceiling fans are exploding and I understand why

@deepcryptodive I got one from CREATE
The one thing I'd be cautious about is what happen when you break the remote control though. Mine has some unidentified RF technology I need to hack to in some ways.

@glgrau Which ones did you get? I'm considering adding them to a new build

This is an excellent explainer and touches on a very real problem for anyone who has been in this space for a while: managing multiple hardware wallets is a pain.
And @Keycard_ Shell makes this problem go away.

Most people think buying a hardware wallet solves the security problem. I ended up with three of them. My security improved, but managing multiple hardware wallets became a hassle. One for trading. One for salary. One for staking. Managing multiple devices got old fast. @Keycard_ solved this for me. I keep separate wallets on separate cards, insert the card into the Shell, verify everything on the device, and sign through QR codes in a fully air-gapped flow. One Shell gives you access to multiple wallets, with less friction, better organization, and more control over your self-custody. Worth a look if you manage more than one wallet.

Just found a reliable organic way to showcase @Keycard_ Shell at crypto events.
1. Go to the crowded merch table.
2. Search for the donation QR.
3. Get your Shell out of your pocket, unlock it, and start prepping a transaction.
4. Someone will def ask what it is and how it works.
5. Turn stranger into cypherpunk.
Proved working at @web3privacy Cypherpunk Summit in 4/5 attempts.
The one fail: nobody asked.

1/ ICYMI: Clear signing is now live.
Hear how the Ethereum ecosystem is coming together to make transactions readable.

This one means a lot!
The people hardening Ethereum's mainnet, carrying a wallet built on the same principles. Couldn't have dreamed up a better home for @keycard_ Shell. 🙏
Protocol Guild@ProtocolGuild
Protocol Guild is excited to announce that all members will receive complimentary @Keycard_ Shell hardware wallets The tools they rely on should reflect the same values they bring to their work: open source, self-custodial, and uncompromising on security

This is going to be a great one! Put it in your calendars!
We can't wait to chat about:
- open source self custody
- clear signing
- @safe UI
- and overall .... how two cool projects created a great UI for power users 😊
ambire.eth@ambire
We'll host @glgrau from @Keycard_ and put the wallets to the test. Live stream on Wednesday, 1:00 PM UTC on @ambire.

@michal1980pl @PaulWilfrevx01 @Trezor did you consider a device where you can actually change the battery your self? like
@keycard_ Shell or
@COLDCARDwallet Q

@YTCryptoGuide @Keycard_ @SeedSigner would love to see your integration of @keycard_ in shieldsigner!

Had a look at the @Keycard_ Shell. Great option to split hardware in such a way as to remove vendor trust. (Works great with DIY flashed Javacard) youtu.be/5NPP4c0D2FM
Core functionally of my @SeedSigner fork (Shieldsigner) but available to normal folk as a retail offering :)

The cool thing about open source hardware is that you can make it your own 👇
I took @keycard_ shell 3d parts on github, ordered some 💁♂️pink parts on shapeways and assembled them without a hitch
