That Pi Zero is cheap AF. And that supplier also has the solderless GPIO pins for like $7. Add the camera and you're good to go for under $30 including shipping. That's a great deal if you ask me. If you get one, I'd love to see a video walk through of your installation of Electrum. That sounds like a very cool project.
But the tradeoff is the additional attack surface, no?
What difference does the additional key make? If I have one encrypted offline key, shouldn't that be sufficient? Or is there some other benefit to using 4 keys that I'm not aware of?
Yeah! I think that's what I was referring to with my comment about enabling notifications, but you should definitely ensure background data and unrestricted battery use is enabled.
Would you do that with Pi OS? Or does electrum have their own OS for use with Pi?
There's no wifi chip on either the SeedSigner or the Portal. SeedSigner uses a no-communication Pi Zero, and the Portal's open-source board only includes NFC capabilities.
Inhave both single-sig and multi-sig wallets. With the multi-sig wallets, I want to have a 2/3 multi-vendor hardware signing configuration. I've already got a Tapsigner for one key, I want a different wallet/signer for the 2nd key, and the 3rd key will be encrypted and stored offline.
Have you updated your Minibits to the latest OTA version? I know they were having some issues a week or so ago, and they resolved whatever the problem was with the latest OTA update. Also, make sure you have notifications enabled for the the app because it uses the notification system to keep it running and able to process zaps. If none of that works, you should DM them because they're very responsive and willing to help with any problems.
I'm talking about hardware signers, not a software wallet. I already use Nunchuk and don't plan on switching. And I use Mycelium as a watch-only backup.
Has anybody tried to connect the NWC payments from Amethyst to nostr:nprofile1qqstxwlea9ah3u6kjjszu6a7lrnhqkfh8eptp2z6v0e9558tlkkl2rgpz9mhxue69uhkummnw3ezuamfdejj7l2r9yx using Citrine as the relay? Does it work?
Yes, works just fine. However, people should be advised that Minibits NWC takes a few extra seconds to process when sending a zap. It's not as fast as Alby, or Rizful, or Coinos. But it does work reliably.
I was just looking at that SeedSigner. Going the DIY route works out to be about $10 cheaper than buying an assembled version. It looks like a nifty little device, simple, straightforward, and purpose-driven. I think my only concern with it is there's no secure element.
Considering that the assembled version plus the necessary MicroSD card is about the same price as the Portal (about $95), I wonder if it would be a better value, and a more secure option to just go with the Portal. On the other hand, the Portal is NFC-only, and doesn't provide any QR functionality for air-gapped operation, and no MicroSD for backup and moving transactions between the device and your computer or phone. It's a tough call, and I'm getting lost in the weeds!
It really is going go crazy in the next 48 hours.
I think at one point overnight it was 2 sats/vB for priority handling.
I know sometimes the future looks bleak, but watching this kid makes me think we're gonna be alright 🤣
I've looked at the Passport, and it is really nice. But it's expensive. I'm just looking for something in the $100 range that's bitcoin only, open source, send secured with a secure element chip. It will be used primarily as a signer with Nunchuk Wallet, so I don't need a lot of the the bells and whistles the more advanced hardware has. I'm currently leaning towards the Portal, but I'm still looking.
Have you seen the Portal? It's another Bitcoin-only wallet/signer that's made for mobile devices. It's powered entirely by the NFC connection, which is pretty novel. It's also reasonably priced, currently selling for $95. I don't know if it's got a secure element chip, but I joined the official telegram channel and asked about it. Hopeful they get back to me in the next day or two. If it does have the chip, it will have ticked all my boxes, and could be the device I choose.
Do you know anything about the Jade? I'm looking at it because it's bitcoin only, and it's supported by Nunchuck Wallet. It's also made by a reputable company (Blockstream) and it's fully open source. It's fully air-gapped, but it does include Bluetooth which can be disabled by downloading the no-bluetooth version of the firmware. And it's cheap. It's selling for about $70.
The only thing that gives me pause is they're not using a hardware secure element chip. Instead, they have virtual SE which uses the security infrastructure to create a protected area of the data storage system that emulates the secure element chip. I'd be happier if they used a hardware SE chip, and bumped the price by $20. What do you think?
I was told birds aren't real.
Cool site! Excellent design, and a great view of the current state of the blockchain. Plus, you can go back in time and review any block. I bookmarked this one!
