For example, can a Trezor wallet with a passphrase be properly recovered in Keystone? I asked chatGPT, and it said no. If the underlying algorithms for their passphrases are different, then they cannot be used interchangeably.
If I set a passphrase and my hardware wallet broke one day. Then I need to buy a new one, and sadly discover that company has gone out of business. What should I do?
If it is true, then I will never use a passphrase on a multi-signature BTC wallet, and buy double wallets for every brand (single-signature with passphrases) to store altcoins.
Hey, Most of the hardware wallet manufacturers are compliant with BIP32/BIP39 protocols. When setting up a new hardware wallet, be sure to safely store your BIP39 Seedphrase, optionnaly you passphrase (if set up) and the derivation path (if you use a custom one). Then you will be able to enjoy multiple hardware wallet from multiple vendors. Even at the same time to get rid of a possible hardware failure.  |

Hey @Tibu I saw you are offering interesting new Satochip blank card in form of SIM card for making our own hardware wallet with Satochip code. If anything happening if this SIM card is entered in old smartphone, or we still need to use card readers and laptops for this card? And is there any other difference compared with other Satochip products? I think this is very cool idea   https://satochip.io/product/satochip-diy-and-developers-card-sim/Hey, Sorry for the long-delayed reply... Yes, you will need a chip card reader or a sim reader to read the chip. In fact, the phone SIM reader could be enough but I doubt you will be able to interract with it directly from a computer and there is no specific mobile phone application to allow such a use. But what about notebooks with a build-in SIM card slot? I think they need a special driver to interact with Satochip SIM card , is this correct? I have 10 years old HP Ultrabook with a SIM slot but don't know where can I get such driver either for Windows or Ubuntu to try your product. Any "SIM" card reader should work. Your 10-years old HP laptop can be perfect as long as you have the driver that comes with. We do not provide any specific driver as our reader are not thight to Satochip project. You can use any standard chip card reader. On Linux, the easiest way to get rid of the reader is to install the pcscd driver. It does the job. sudo apt-get install python-usb pcscd
sudo systemctl enable pcscd.service
sudo systemctl start pcscd.service
sudo systemctl status pcscd.service
But on Windows, it can be painful. Try the generic one that comes with Windows when you plug a SIM card into the SIM reader. It might work out of the box. Happy to help. |

Huh, that is interesting! I was just playing around with my Satochip when I decided to check out the HW wallet section to do a little research on it after the Ledger debacle, and I came across this old thread. The SIM format is probably over my head, but I do like the newer products coming out from the developers of the Satochip. By the way Tibu, this question was never answered and I'm curious about it myself (though I don't recall ever reading that on the Satochip site: "The Satochip hardware wallet has full BIP32 and BIP39 support and also supports the import of regular (non-BIP keys) such as vanity keys. Even more, private keys cannot be exported outside of the secure chip. Up to 16 regular keys can be imported on the chip. "
What does it mean? You can import into Satochip single private keys which were exported from, say, Core?
One by one?
One other thing that I hope isn't too far off-topic: As I was reading the description of the DIY SIM wallet I noticed that it's badly in need of some editing. As an example: You want to upload your own firmware (Satochip, Satodime or Seedkeeper) but wants to use the smallest form factor as possible ? That's sloppy English, and I always say if you're going to be writing English on a website it better be flawless (or as close to it as you can get). You've got a space between possible and the question mark for some reason, and that's in addition to the incorrect form of want. Isn't this much better: You want to use the smallest form factor possible when using the Satochip, Satodime, or Seedkeeper firmware? We've got you covered with a compatible javacard, pre-cut into a SIM card-sized chip. Yeah I'm a grammar Nazi, but when I see pages like that and the writing is....bad (sorry, just giving it to you straight)....it's a turnoff, even if I like your product very much. If you ever want some editing done, I'm cheap but thorough. Boy, I missed that link altogether when you posted it, and I'm going to check it out now. One of the reasons I was browsing this section for Satochip info was to get answers to some of those same questions. Hello, Sorry for the delay. I'm not very often here. Regarding the keys import, your previous assumption regarding Electrum was right. In fact, you can importe BIP39 seedphrase but also other type of seed. Maybe we should rephrase this to be more clear. I have update the SIM product page: https://satochip.io/product/satochip-diy-and-developers-card-sim/You are right, we should be more careful with English translation. This one is way better. Thank you! |

Hi, I am the creator of a website where I compare more than 30 different hardware wallets, feature by feature: https://wallets.thebitcoinhole.com/I am adding Satochips to the site but I have some doubts about its features. Maybe here someone can help me to clarify them. 1- Does Satochip has any supply chain/physical attack protection? 2- The firmware inside the Satochip can be upgraded? How? 3- Does Satochip has passphrase support? How? 4- Given that Satochip can be connected with thirdparty apps like electrum, this means that it supports features like multisig, coin control, custom node and testnet? 5- Is any kind of user added entropy when generating the private key? Thanks Hello mate... We already had a talk recently but I will provide a detailed explaination for everyone. ... ... -> https://wallets.thebitcoinhole.com/ |

BREAKING NEWSI deprecated the Google Spreadsheet and launched a new website comparing 32 Hardware Wallets: https://wallets.thebitcoinhole.com/The site offers some advantages compared with the spreadsheet: - Improved usability and look & feel - Possibility to filter wallets so you can only see and compare the ones you are interested - Added more contextual information about each compared feature - Fixed some data errors. - It is open source, so everyone can suggest changes or fix errors: https://github.com/thebitcoinhole/hardware-walletsI plan to continue adding more features and wallets to compare. Wow... Website is clean and well designed. Good job. But its still missing Satochip hardware wallet ( https://satochip.io), wen sir ? Do you have a github page or something like that to allow contributions ? And I have the same request for the seed storage solution part : https://thebitcoinhole.com/seed-backup/  Have a great day. |

Hey, I you are looking for a reliable AND secure solution to gift #Bitcoin (or any other cryptocurrency), that is also portable and easy to use (with a mobile phone for exemple), I suggest you to take a look at Satodime: https://satodime.ioSatodime is a chipcard ( dual interface so you can use it on your computer but also on your mobile phone with the NFC) that allow you to: - create up to 3 keyslots (called "vault"). - Seal a new keyslot -> the chip will generate a pair of keys (public/private) and hide the private key within the chip memory. - Send funds to the provided public address (QR code flashing etc...). - Unseal a keyslot -> the chip will reveal the private key to the user. - Reset a keyslot -> the chip will erase any information regarding a specific vault. Desktop app to manage the card available on MacOS, Linux and Windows - also tested on TailOS for example. Mobile app available on Android - Google Play Store - and iPhone (currently on the Testflight but will be released very soon). Use cases: - Gift - no need to trust someone. You are able to check by yourself if a vault is seal or not and its balance. - Do transaction "off-chain" - if you exchange Satodime hand-to-hand, there is no record in the blockchain. - Use it as a tip jar: create a Bitcoin keyslot, print the corresponding QR code address and accept crypto-tips directly on your card. -... Advanced features: - It supports several crypto-currencies and non fungible tokens (segwit fir BTC is also supported). - You can provide part of the entropy used to generate the private key so you are sure that nobody has pregenerate the keys before (when you unseal a keyslot and get the private key, the entrepy used for its generation is shown to the user). - There is a "ownership" protection to avoid people scanning the card on street. Only the owner of the card can perform sensitive action (Seal, Unseal, Reset). Last but not least, the project is open source - yeah baby.  |

Hello, Seedphrase storage is a real HOT topic. While the HW market leader (aka Ledger) keeps asking its users to write down a sheet of paper their 24 words, I think it's a BAD PRACTICE and a non sense. Rules should be: never write down a sheet of paper your seedphrase and never in plain text. Take a look at Seedkeeper : https://seedkeeper.ioIt's a chipcard equiped with a secure element designed to store your seedphrase securerly. Access to the chip memory (where is encrypted the seedphrase) is protected by a PIN code (from 4 to 16 chars). Last but not least, this solution is fully open-source and affordable. You can get multiple chipcard for multiple backup.  |

If by "durable" you mean only the material used to make the device, it is better to use metal than plastic.
But if by "durable" you mean "long lasting", it is better to choose the device with the least sophisticated electronic components. Yeah I agree with you, and I agree that credit card style hardware wallets could be most durable hardware wallet devices...they are so thin and small that you can easily make them fireproof and waterpoof. A smart card such as Tangem, Satochip or Satscard might be the best choice for long-term storage.
Since you are here, is Satochip and other cards you sell waterproof by design? Yeah... I'm a big fan of "the less tech you have, the longer you will stay". And yes, cards are "waterproof". You can immerse chipcard in (non-corrosive) liquid for several minutes without any effect on the hardware. I'm doing it everytime I drink a beer and show a demo of our cards |

If by "durable" you mean only the material used to make the device, it is better to use metal than plastic.
But if by "durable" you mean "long lasting", it is better to choose the device with the least sophisticated electronic components.
The biometric kit, the camera, the color screen and the battery do not have a long life (especially the battery).
And if you have to rely on these components, your hardware portfolio will not be "durable".
A smart card such as Tangem, Satochip or Satscard might be the best choice for long-term storage.
What if you could simply "detach" the secure element from the rest of the device? So that you can plug it into another compatible device when the first one dies? Thinking out loud...

Nothing fancy will be posted while I collect information, but this could be updated later.
Thank you for posting your suggestions and new wallets with links.Hey, How about add Satochip and Satodime ? Well, Satodime is not a hardware wallet because you can't sign using the device. It's more like an Opendime on steroid. Like a bearer cold storage solution. But Satochip is a hardware wallet and is NFC enable. Today you can't use it with your smartphone cuz we dont have develop the mobile app part - yet. But it will come later this year ! Hit me up if you need any other information in case you wish to add these two lil' open-source - super - products  |

Hello, I'm deeply sorry for this delayed reply. This thread was not monitored.
Yes, yes and yes, you can use your built-in smart card reader with our Satochip products.
In these laptops, you might also have a built-in NFC reader.
Have a great day.
Thank you for your reply. I haven't bought a hardware wallet yet, so it's better late than never. I've tested it with an old debit card, and at least it seems to detect that something with a chip has been inserted. Is there a more valid way to check that the port is working since, as dbkit98 mentioned, most of these have only been collecting dust? Moreover, one more question, in case you know: do I need any specific software to use it on my computer? I don't have NFC though, a smartphone would work just fine I guess? Thanks in advance If your laptop "detect" a card, it's enough. If you want to be completly sure, you can check and list all the chip card reader present on your laptop using this tool : https://github.com/martinpaljak/GlobalPlatformPro/releasesIt's a small tool that allow you to deal with chip card and card reader. Regarding our product, you will need a software client to interract with the card, like Metamask or Electrum, we provide such software with Satochip integration. And regarding the mobile integration, the card is NFC ready but we dont have a mobile app yet. Meaning you wont be able to use it out of the box with your smartphone today. But pretty sure you will be able to do so later this year. Have a great day. |

You think this could also work with older Thinkpad business laptops that have ID card readers and all other brands? I might have few of this laptops collecting dust and I never tested how this card readers work, but companies use this along with fingerprint scanners. This machines certainly don't have NFC support since this was invented later, but I I can always use smartphone for this. Yes. Had an old Thinkpad ans it's working well. Some high-end Dell or Lenovo laptop does have a built-in NFC reader. And it works too. Any generic chip card reader, built-in or not, work fine. |

Hello there, I find the whole concept quite interesting, it's quite convenient and stealth looking. However, it's mentioned in your website that the smart reader is also required. My question now is if that can be avoided, since my laptop (HP Probook) has a so-called smart card reader. Do you have any clue if there's any compatibility or is it a completely different thing? Excuse me if my question sounds stupid but I always wondered how that card reader could be used. Photo for reference  Hello, I'm deeply sorry for this delayed reply. This thread was not monitored. Yes, yes and yes, you can use your built-in smart card reader with our Satochip products. In these laptops, you might also have a built-in NFC reader. Have a great day. |

Hardware wallet ecosystem can be a jungle for newcomers... And it's even more true when the marketing kicks out (fancy screen, +10000 (shit)coins supported, finger print sensor...)
Imho, the best security is the one you can manage from A to Z, knowing the risk on each steps and how to mitigate it. No need the latest high end, fully equiped hardware wallet that will soon or later no more working because of a poor camera or a poor finger reader, right ?
I'll keep on eye on this thread...
By the way, thank you for this very helpful thread.
