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.
https://image.nostr.build/ee9edfd97e783adf722f62e39f007ed71a82f2141103eacfab47ba1f54cd8e6b.png
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.
https://image.nostr.build/e48576bd1d61296d4016a455a2d24678134d87d11881458ab52aa31cdb11cf41.png
https://image.nostr.build/169626b3efb136a2f47aa4b3f27989fdd8c820cacb38a8017216e5d44ea94a2e.png
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.gz
https://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.jpg
https://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)
Any other best practices? Comment below 😀
These are the seed plates I recommend https://svrgnty.com/resources/storage-backup/

8/ Conclusion
👍 @npub1wu4…3vw0 Coldcard Q, @npub16s4…4p24 3 Pro, Krux, @npub1wu4…3vw0 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

2024-05-26 15:22:22

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 @npub1wu4…3vw0 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

2024-05-26 15:20:34

5/ Good @npub16s4…4p24 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.jpg

2024-05-26 15:16:11

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

2024-05-26 15:14:27

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

2024-05-26 15:13:35

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.

Upgrading some of my #Bitcoin nodes to Raspberry Pi 5 with PineberryPi HatDrive! Bottom and 2TB NVMe.
RaspiBlitz and Citadel working like a charm with latest release candidates. And with rsync was able to sync everything over 💪. MyNode works on RPi5, but cant get NVMe to work as data drive, does work as OS drive though...
Got Umbrel up (set boot from nvme, install Raspberry Pi OS, then install umbrel, then rsync) and it works perfectly for 15-20 min then crashes, HatDrive ACT light starts flashing 😕
Start9, no luck at all... 😭
Raknex fit is tight at the moment 😅

/9 What is my favorite? They all have pros and cons, but I do have some preferred nodes:
1. StartOS - Currenty is my main node and the one I use the most
2. RaspiBlitz - I just love the screen, and love looking at it every time I walk by it
3. Citadel - Still in the early development phases, it resembles the first versions of Umbrel, though with better privacy. I really look forward to the Nirvati release, good chance this becomes one of my top 2
4. @umbrel - My first node and still in use for apps not available elsewhere, but the security and privacy issues, + switch to home server are a turn off.
5. MyNode - The license requirement can be a turn off for some, but an advantage is that it is bitcoin only node

8/ Citadel
Pros
+ Https: local network communication is encrypted, though it needs to be setup
+ FOSS (free and open-source software)

Cons
- Still in heavy development, and lacking many apps (temporary)
Neutral
~ Though still in development, it is very promising. With the release of Nirvati I expect this to be a top tier node

7/ @umbrel
Pros
+ Nice interface
+ Probably the most popular node (and the one I've had the longest) so there is a large support community
+ Biggest selection of applications, also has apps not available on other nodes like Nostr Wallet Connect from @getAlby
Cons
- Telemetry collected seems unneeded and a privacy concern. https://twitter.com/runcitadel/status/1680227793106247681
- Connecting wallets can be confusing (Bitcoin Core, Electrs, Lightning)
- It is currently in beta and is not considered secure. Would not use as a primary node. https://github.com/getumbrel/umbrel/blob/master/SECURITY.md

6/ MyNode
Pros
+ Just Bitcoin
+ Https: local network communication is encrypted
Cons
- Does not require a license, but does "unlock" certain features like updates, which otherwise would be much more difficult.
- Out of all nodes, probably my least preferred UI

5/ RaspiBlitz
Pros
+ Though not required, I do recommend the screen. It provides details about your node without the need to access the interface. It is also eye candy
+ Just Bitcoin
+ FOSS (free and open-source software)
+ Https: local network communication is encrypted
+ Nice CLI
Cons
- Unlike all other nodes, it does not provide a url to access the interface, but instead you need the IP (it is displayed on the optional screen)
- The installation process can seem more complex for a noob, e.g. having to select a Lightning client
- No update notifications
Software versions on 12 July 2023:
Bitcoin Core: 24.0.1
Mempool: 2.4.0
Specter: NA

4/ Start9 StartOS
Pros
+ Nice interface and easy to use
+ Though not as extensive as Umbrel, the marketplace has enough applications to easily get up running quickly
+ Https: local network communication is encrypted
+ Most up-to-date
Cons
- Specter seems to be a bit buggy. Not sure if it is due to the newest version having more bugs, the computing power of the Raspberry Pi, or the implementation for StartOS. Though refreshing the page usually resolves issues, it is frustrating
- Missing Bitcoin Explorer

2/ Off topic, but for those curious what the 5 screens are, they are nerdminers by BitMaker_ on a #nerdminer 1U rack by sulfuroid. Nerdminer is a lottery miner. It is great FOSS project that allows you to learn about bitcoin mining
https://image.nostr.build/48536295f5720ef19da32a42b1cdab0dc13b48b9316e679560b5c52bc040aa90.jpg

1/ Over the past months I've tested various #Bitcoin nodes that run on Raspberry Pi. The nodes tested are pretty simple to setup and don't require technical skills, anyone can run one.
Before we jump in with my thoughts, some notes:
My main reasons for having a node:
- contribute to the bitcoin network's security and decentralization
- connect bitcoin wallets to maintain privacy
- explore the blockchain with @mempool and Bitcoin Explorer (bitcoinexplorer.org)
- create multisig wallets with Specter Desktop
- create lightning channels
Some of the nodes below take the home server approach, i.e. they want to be your private server used as a replacement for many cloud services. While this is a great way for users to learn about self-hosting and data ownership, I would not recommend it. My preference is to keep node and bitcoin related apps separate from other home server applications. Luckily you can simply opt to not install/remove any of these apps and keep it a pure bitcoin machine.
For each node I indicate software versions for Bitcoin Core, Mempool, and Specter on the date I started putting this together. All nodes receive updates regularly, but some are faster than others.

3. @foundationdvcs Passport
Followed by
- Trezor One & Model-T
- Specter DIY & Shield
- BitBox02
Least preferred
- @Blockstream Jade

- Ledger

2023-06-25 16:03:27

Ledger devices
I just cannot recommend their devices. While I have used several in the past (Nano S), the company not aligned with the values of the Bitcoin community, instead focusing on altcoins. In addition the company continuously discredits itself by (just to name a few):
- Promoting horrible security https://twitter.com/Ledger/status/1648657754834325504
- Making deceptive claims https://twitter.com/Ledger/status/1592551225970548736 and then the now deleted tweet "Technically speaking it is and always has been possible to write firmware that facilitates key extraction. You have always trusted Ledger not to deploy such firmware whether you knew it or not."

2023-06-25 16:03:01

Good @SeedSigner
+ Full-fledged software and great UI
+ Built with off the shelf components
+ Just feels good putting together your own device
+ Great community
+ Dice rolls for entropy, though limited to 99
Bad @SeedSigner
- In an era of government-imposed lockdowns impacting supply chains, it can difficult or expensive obtaining a Raspberry-Pi
Neutral @SeedSigner
~ Stateless, requires importing seed every time it is used
~ Best if used with a 3D printed case as the buttons and joystick on the waveshare hat can be rough edged
~ If not experienced, best get a Raspberry Pi with pins, as adding them can be difficult
https://void.cat/d/N13PzSvYRtej8cf7kbhLxu.webp

2023-06-25 16:02:06

Good Specter DIY & Shield (1 of each tested)
+ Built with off the shelf components
+ Just feels good building your own device
+ Large screen which makes it is easier to read and display information
+ Dice rolls for entropy with additional app https://github.com/xavierfiechter/specter-diy-app-dice-rolls
Bad Specter DIY & Shield
- Screen seems too reactive. If used with a 3d printed case, need to be careful with the case edges touching the screen
- (Shield only) Cannot remove battery without disassembling the device
Neutral Specter DIY & Shield
~ Large device
~ Stateless though with the Shield version you can use a smartcard
~ Specter Shield is probably more of a collectors item, difficult to obtain
https://void.cat/d/UFEUYPmkgPCZS8VH1iRf8C.webp

2023-06-25 16:01:22

Good BitBox02 (1 device tested)
Good
+ Solid product
+ Good for multisig
Bad BitBox02
- Not air-gapped
- Bitcoin-only firmware available, but also supports altcoins
- No dice rolls for entropy
- Wallet setup requires software
https://void.cat/d/AAcDtC4TigYtpCGnqf7Kp4.webp

2023-06-25 16:00:42

Good Trezor One (3 devices tested) & Model-T (1 device tested)
+ No closed source elements
Bad Trezor One & Model-T
- Not air-gapped
- Bitcoin-only firmware available, but also supports altcoins
- No dice rolls for entropy
https://void.cat/d/Sk5AjZ9pXAjNFBKqoNjNnE.webp

2023-06-25 16:00:01

Good @Blockstream Jade (2 devices tested)
+ QR signing
+ Price
+ Bitcoin only
Bad @Blockstream Jade
- Wheel feels flimsy, on first device, it often got stuck
- Built-in battery that cannot be removed. Impractical for long-term storage
- Wallet setup requires software
- No dice rolls for entropy
- Poor camera
Neutral @Blockstream Jade
~ Build quality
https://void.cat/d/Sw8W5wJRsGGfbnyQ89Pzr3.webp

2023-06-25 15:59:10

Good Coldcard Mk4 (5 devices tested)
+ Many security features such as duress pin and keypad scramble
+ Might seem complicated or overwhelming, but it is great for learning, and you quickly find your way around
+ Bitcoin only
+ Dice rolls for entropy
+ Overall good build
Bad Coldcard Mk4
- Initially the SD card got stuck, rubbing on the plastic casing. Of the 5 devices tested, had the issue on 2. After some usage it seems to no longer be an issue
- When using the magnetic USB adaptor, you cannot slide the protective cover on the back
- Controversial topic, but the code is not open source. Though not an issue for me, and they are free to choose the license they want, the discourse with the FOSS community often seems misleading and aggressive; unnecessary
Neutral Coldcard Mk4
~ Seems with firmware updates, menu items often move around, creating confusion
https://void.cat/d/7KenewsVhc9uTQHPcWuErn.webp

2023-06-25 15:57:55

Good @foundationdvcs Passport (2 devices tested)
+ Solid build (except keypad)
+ Camera and QR signing
+ Removable battery
+ Bitcoin only
Bad @foundationdvcs Passport
- Hard to remove the SD card, sometimes need to remove the back panel
- Lack of security functions like keypad scramble
- The keypad feels cheap and looks like it will wear out after some usage. Sometimes had to press keys more than once
- "Security Words" experience poor, often found myself continuing to type when it was paused on the words
- No dice rolls for entropy, though may be available in future
Neutral @foundationdvcs Passport
~ Color display, but really brings no additional value at the moment
~ Might be too simple. Understand KISS and the device works, but seems to be bare minimum in security features
~ Though accounts are in separate tabs, you do not need to be in a specific account to sign a transaction. Unexpected behavior but can avoid a heart attack if a transaction was rejected
~ Slightly larger than other devices and does not fit in "standard" faraday bags
