And just to clarify, I discussed generating a seed with dicerolls using multiple devices. This is done to ensure your device is not compromised. For example, using 2 devices, one will be your main device and and one the verification device. You should generate some test seeds by inputting the rolls into both devices to verify that they give the same outcome. Once you have verified that the outcome is the same, then you should generate a new seed only on the main device!
How to install Sparrow Wallet on Tails persistently #bitcoin
Tails is a portable and FOSS operating system that protects against surveillance and censorship, and can run on a USB stick.
Sparrow is a FOSS Bitcoin wallet for those who value financial self sovereignty. Sparrow’s emphasis is on security, privacy and usability.

If you don't already have Tails, the instructions on their website are straightforward, just select the OS you will be using to create the USB stick and follow them.
https://tails.net/install/index.en.html
Once you have Tails, you will need to enable Persistent Storage and Dotfiles so that you can install Sparrow Wallet and add it in the navigation bar.
You can enable them during setup or from: Applications > Tails > Persistent Storage.
Once you have that set up, you can continue with installing Sparrow.

1. Start Tor browser and go to
https://github.com/sparrowwallet/sparrow/releases/latest
The version listed there will be the version downloaded. Currently the latest version is 1.9.1, if a new version comes out, just replace 1.9.1 in all the commands below with the version number you are installing.
2. Go to Applications > Utilities > Terminal to open a terminal and run the following command to create a Downloads directory:
mkdir ~/Persistent/Downloads
3. Next we will change to the newly created directory and download Sparrow Wallet:
cd ~/Persistent/Downloads
wget https://github.com/sparrowwallet/sparrow/releases/download/1.9.1/sparrow-1.9.1-x86_64.tar.gzhttps://image.nostr.build/a6877b3f7acdcf40190cfce73702005bc184fa5e4881b8791ebacf41a56f86ae.png
4. Next, let's download the manifest files to verify the software:
wget https://github.com/sparrowwallet/sparrow/releases/download/1.9.1/sparrow-1.9.1-manifest.txt
wget https://github.com/sparrowwallet/sparrow/releases/download/1.9.1/sparrow-1.9.1-manifest.txt.asc
curl https://keybase.io/craigraw/pgp_keys.asc | gpg --import
5. Now let's verify Sparrow Wallet with the following 2 commands:
gpg --verify sparrow-1.9.1-manifest.txt.asc
sha256sum --check sparrow-1.9.1-manifest.txt --ignore-missing
For the first command, you will see "This key is not certified with a trusted signature!". This means that PGP doesn't place a high level of trust in the key downloaded from the internet. For this step to be considered successful, look for Good signature.
If the output of the second command does not end with OK, do not proceed. If it ends in OK you are good to go.
https://image.nostr.build/d79025ffa277c9b8db15b88df5ea18ef544dd9395b57540ec54c1f112282c88f.png
6. Unzip the downloaded version in the Persistent folder:
tar -xvzf sparrow-1.9.1-x86_64.tar.gz -C ~/Persistent
7. Create a Desktop icon to more easily access the application:
mkdir -p /live/persistence/TailsData_unlocked/dotfiles/.local/share/applications/
nano /live/persistence/TailsData_unlocked/dotfiles/.local/share/applications/sparrow.desktop
8. Paste the following in nano, then press CTRL + X, followed by Y to save:
[Desktop Entry]
Name=Sparrow Bitcoin Wallet
Exec=/home/amnesia/Persistent/Sparrow/bin/Sparrow -d /home/amnesia/Persistent/Data
Terminal=false
Type=Application
Icon=/home/amnesia/Persistent/Sparrow/lib/Sparrow.png
https://image.nostr.build/5120ad6abb7f1cb295bd731622c641609dbd949c34fc87c3946385dc8cf05fb7.png
And there you have it 💪, restart and then you can open Sparrow Wallet from the navigation bar in Applications > Other > Sparrow Bitcoin Wallet
or from from the terminal:
~/Persistent/Sparrow/bin/Sparrow -d ~/Persistent/Data
https://image.nostr.build/0a9246005f01d6afdbde64f0f835809903ce59fad9cac7cedda9026d3ae9199a.png
Sparrow is now installed in ~/Persistent/Sparrow/ and your Sparrow confs and wallets will be in ~/Persistent/Data allowing for easy updates.
To update Sparrow when a new version is available, just repeat steps 3 to 6 replacing the version number.

It's crucial to secure your #bitcoin seeds on metal. Putting your seed to metal ensures durability and longevity, protecting it from physical damage, fire, and water, and safeguarding your bitcoin.
Here are some best practices and tips on how to do that:
https://image.nostr.build/a42197e005155d6b8f6808482bc3de76d6087dbf408f2f17350e339552df1c66.jpg
While there are many types of storage methods, I recommend a single center punched, stamped, or etched metal plate per seed. Center punched is the easiest with an automatic center punch. If you are making several plates, an automatic center punch with a palm rest will help.
https://image.nostr.build/335817fa403330919fba5d047c2e8f07efaf87151152efbfea66af134479480b.jpghttps://image.nostr.build/cf7a83e250015f46f89723bebe31d0933ef3d12fdec0a08384ab6751a533dd5c.jpg
When selecting a seed plate, ensure it is a high quality metal, at a minimum 304 stainless steel or better marine-grade 316L stainless steel. Titanium is also good. Lower grade metals have a higher chance of corrosion or melting.
https://image.nostr.build/b3fca5601f918027bc0fabbb0c432714fcb03d0ef6be4ae98ecf5ce648a818f3.jpg
Use one plate per seed. When multiple parts are involved, there is a higher chance of permanent loss of data if the parts are separated.
https://image.nostr.build/0c796f3e5268fe6c4b1e57d22eb2e1b2c3af0d7d1345970ec4bd3091ce2894d1.jpg
Unless you have a particular threat model, avoid seed plates that are too small. Smaller ones become more difficult to read and mark, not just for you but also loved ones (think inheritance). They are also easier to lose. Stick to a standard size.
Before handling your seed, check your environment. Make sure cameras are turned off, phones are put away and covered, window shutters closed, etc. This may seem extreme, and chances may be low, but you are protecting your wealth. Last think you want is compromising your seed.
Use a permanent marker to mark the seed before using the center punch or etching. Verify you have not made mistakes before marking. When marking, it is easy to mark the wrong letters for example mixing O and Q or N and M.
When you start the marking, stamping, etching, ensure marks do not remain on the surface, revealing data about your seed. Preferably, use an anvil. With the automatic center punch you don't need more than 2 punches per letter.
https://image.nostr.build/aaa61da7fdc46b13ef5a585ac31fd104fe8adf9e0632b0be53afd80687c380dd.png
If you use a center punch with a hammer, start easy, chances are you will hit too hard a warp/mark the other side of the plate too. Stamping or etching can be also trickier to mark and read, though e.g. a physical guide can help position the stamp.
https://image.nostr.build/7ca78dfb2ad46914ffa071006a5c6c7865d0e357ed89dbf2810444ef80f6b101.png
If you make an error, don't worry. Define a method and document it with your recovery process, e.g. add a second mark to the error square and then mark the correct square.
https://image.nostr.build/3c0e8ca79dad2f3e35b198c75b34a5b44e984a930070459a97d39152d44d92c8.png
Side note: you should have your recovery process documented. I would recommend having a copy in encrypted notes and a printed copy with your inheritance plan. (see privacyguides.org)
For a hardware device, if new, I would recommend deleting the seed from the device, re-importing it using the seed plate, and ensuring the fingerprint matches. This acts as an additional verification that the seed is correct. Never scan or type your seed into an online device.
Label your seed. Don't use the fingerprint, it can reveal the use of a passphrase. Don't use the device name, the device can change e.g. upgrading to latest model.
If the seed was initially on paper before putting it to metal, burn the paper, there should be no traces of the seed left.
Place the seed in solid cardboard envelope. This so the surface and markings do not reveal any information. Then place it in a tamper evident bag.
https://image.nostr.build/a92321f8087a05cbc13b6bd96902b79f3fcf048ddfd31297430d831cc2a56912.jpg
Store the your seed plates in a secure location. This will get a post of it's own at some point 😅.
Conduct regular health checks. Every quarter inspect the tamper evident bag for signs of tampering, and every year unpack the plate and check it for signs of damage or corrosion, then repack (remember environment)

8/ Conclusion
👍 @Coinkite (old npup) Coldcard Q, @Keystone 3 Pro, Krux, @Coinkite (old npup) Tapsigner, I like them all
🫳 Trezor Safe 3 is good
👎 Bitkey will have it's user base but I wouldn't recommend it to you
If you enjoyed, repost and like 🙏, and checkout https://svrgnty.com for the best #bitcoin resource
7/ Bitkey
For this one, no "good, bad, and neutral", as I was never able to complete the setup. I'm not writing-off bitkey, they delivered a high quality product, and I hope with future releases to see improvements, but this one is just too locked down.
To start you can only use it with their app. Not the main issue, but would be nice if it could be used with other wallets. Next, at least for android, it requires Google Drive. If you are a Bitcoiner, or on that journey, you will inevitably become more privacy conscious.
Depending how deep you go down that path you may not have Google, which is my case. Not having Google, I just abandoned it. Maybe with future software releases they will support other cloud providers, but for now nothing. I will wait and see.
I'm sure it will appeal to some user base, but if you are on bitcoin twitter/x, you are not one of them, all other hardware wallets mentioned above are better options for you.

6/ Good @Coinkite (old npup) Tapsigner
+ Convenience
+ Can carry in wallet
Neutral Coinkite Tapsigner
~ Backup password is printed on the back of the card and looks like it could rub off easily. Make a copy when you set it up!
~ Not a negative, but it has limited support. Some good wallets support it, but not all
Negative Coinkite Tapsigner
- Not a real hardware wallet, don't trust it's durability for cold storage
Overall
Great to use for e.g. signing on a mobile app, or as a signer in a multisig that is used regularly, for quick and easy signing
https://image.nostr.build/9139920e3344b37f6987c7372a28e13c7e5fa5484842a24e41644853e2f6bc53.jpg
5/ Good @Keystone 3 Pro
+ High quality build, solid materials, feels almost like a smartphone
+ Open source
+ Good size, not too big not too small
+ Allows up to 3 wallets, could see this coming in handy for some use cases
Neutral Keystone 3 Pro
~ Good experience though I found the "..." menu on top a bit hidden, found myself navigating through menus searching to then find the options I was looking for where there. For the dice rolls I had to search online, initially didn't find it
~ I am a fan of dice rolls for entropy, but it is a heated topic, as not doing it correctly can end with lost funds. I would improve the experience here by requiring either 50 for 12 words or 99 for 24 words. Right now you can create 24 words with 50 rolls
~ Would love to see a keypad scramble option for the pin, especially due to the touchscreen and fingerprints remaining
~ The bitcoin-only firmware is in the early stages, but it has a lot of potential, and I believe we will see quick improvements
Bad Keystone 3 Pro
- Not a fan of the SD card slot positioning. Really had a hard time getting cards in. That said, its not something used regularly, only used it for firmware updates
- Built-in battery that cannot be removed. Not optimal for cold storage
Overall
Better than expected. It's easy to use and feels like using a software wallet. I would recommend this to someone starting self-custody, a friend/family member, who isn't going to go all the way down the rabbit-hole. Also perfect as a signer in a multisig setup
https://image.nostr.build/124e4a3ec32764c6f9c7f08a936808a5dde001574bb3dc96f256daabcf031945.jpghttps://image.nostr.build/26a7bae573f0beec302a282a794becfc9347a1b3a69417d1f70c81f1047a0a70.jpg
4/ Good Krux
+ Awesome open source project that works on off the self devices
+ Supported on many devices. Don't want a battery? Get a device without. Want a larger screen? Get a larger screen device
+ No assembly required, just flash it (also very easy)
Neutral Krux
~ Stateless, requires importing seed every time it is used
~ Though supported on multiple devices, some are hard to get. I tested the M5StickV but really wanted to try the Maix Amigo, which is sold out almost everywhere
Overall
Nothing negative to say on this project, it's great 💪 and a perfect addition e.g. to a stateless multisig setup with @SeedSigner and @Blockstream Jade for a multi-vendor setup, reducing the risk of both supply chain attacks and device-specific attacks.
https://image.nostr.build/fbfdc8913b8053c225ba84c286edd0c6333f5548be4b39daf68f929c1983bba1.jpg
3/ Good Trezor Safe 3
+ First Trezor hardware wallet with a secure element
+ Open source
+ Easy to use and beginner friendly
Neutral Trezor Safe 3
~ It is basically a Trezor One with a slightly new look and secure element
Bad Trezor Safe 3
- Requires Trezor Suite (desktop or web) to initialize and install firmware, meaning you need to install software
- USB only, which means again that it requires additional software (trezor bridge) e.g. for it to work with Specter Desktop
Overall
Decent hardware wallet if you don't mind installing additional software. It is good to have as an emergency backup device stored with an inheritance/recovery plan, given there is no battery, it is small, and easy to use for beginners too
https://image.nostr.build/df3505fd109fab730e93b40e2e5a5000761a7c8d4915ba751fb6f71747a1cd63.jpg
2/ Good @`Coinkite` Coldcard Q
+ QR code signing, faster and easier
+ Keyboard 🙌, if you have ever tried importing a seed or used a passphrase on the Mk4, you will really appreciate it. The keys are small and it will feel strange in the beginning, but you quickly get use to it
+ Most fully featured hardware wallet, with never ending options
+ Standard size batteries that can be removed and easily replaced
+ Large screen, much easier to read
Neutral Coldcard Q
~ Larger than MK4, makes storage more difficult, won't fit in a faraday bag
~ Firmware (1.1.0Q) a little buggy. It crashed the first time I tried importing a seed. QR reader also remained on once with red light flashing, even though I had exited the function
~ Firmware (1.1.0Q) not fully updated from Mk4, e.g. when exporting the wallet to Sparrow, it seems only option is to export the json to an SD card (has not been updated), only once you proceed does it mention the option to use QR. All small thinks that will for sure be fixed with time
~ Found the keyboard scramble confusing 😅🙈 and disabled it. Maybe if it was at the bottom of the screen and the onscreen keypad looked like the buttons (a border around each number), it would be less confusing
~ Would be nice if the QR reader gave feedback while scanning
Negative Coldcard Q
- The build quality is decent and similar to Mk4, but it feels different. The clear case on the front is beautiful, one the back is looks a bit cheap. On the sides, where the case comes together there are some rough edges. You also have these rough edges on some Mk models but due to the form factor and being smaller, it is not noticeable. On the Q it is, and due to the size and how I held it, it actually bothered me and I had to smooth the edge with a razor blade.
Overall
The Mk4 is my favorite, but the Q is right there. The Mk4 is great for cold storage, locked away and only pulled out for regular audits. The Q is similar BUT it can also be a "daily driver". Large screen, QR signing, and keyboard, make it great for regular usage.
