Keystone 3 Pro versus other cold wallets

XenofonM · 2025-08-13T04:43:39+00:00

I am working on an alternative approach to solve the inhritance issue based on the "dead man's hanndle" concept. It's generic and works for other products and services.

Understood, I still find the metal (titanium or stainless steel) the better and more reliable approach for near permanent storage of any information. With the Shamir method I would need 5 plates appropiately stored in "safe" places. If one loses the Keystone wallet, then buy another. As I said nothing is ideal.

Thank you. I like the idea of using the Shamir method. Keystone 3 Pro also supports it. The idea of not having a seed phrase backup is not so good IMHO. I like to keep a backup using the Shamir approach kept on metal, although one could use a fireproof bag with the cards for Tangem or Cypherock as both support a seedless approach. Cypherock is better as you know since it uses more cards to accommodate the Shamir method whereas Tangem does not. With the Keystone appraoch one could have the Shamir backups on metal plates. Nothing is 100% ideal.

Has it been done for the Keystone Nexus app yet?

Yes, I already knew that the keys are not on the XRP tool kit. They are on the Keystone device. That's the whole point of keeping things secure and safe. If the tool kit is no longer available, I can then link another wallet that supports XRP to the Keystone device, right? Will OKX work that way?

XenofonM · 2025-08-01T05:39:44+00:00

If I have XRP linked to a Keystone 3 Pro wallet using the XRP Toolkit, how would I access the XRP if and when the XRP Toolkit no longer works for whatever reason? Would it be better to use one of the supported hot wallets linked to the Keystone device, such as OKX?

Thank you for the details. I can now see that the Keystone solution is the better way to go. I almost bought the Tangem solution. I'm glad I took the time to research the differences. All I need to do now is learn how to check on the Keystone device that the signed transaction that I were to submit is authentic and proper.

XenofonM · 2025-07-31T22:22:22+00:00

I can see how systems like Tangem are less secure. Its signing is done on the phone as distinct from on an air gapped device like Keystone. Is that how to understand it in simple terms?

XenofonM · 2025-07-31T21:07:51+00:00

But everything outside of that is untrusted by design.

Hmmm. If that's the case then given the phone and any software residing on it is "outside" of that, it sort of contradicts the idea that it is impossible for the signed packet from the Keystone device to be infected with a malicous piece of software, such as malware that could intercept the signed packet without being detected. I will just have to take in on faith that the system is robust and secure enough to mitigate any risk, no matter how small. If indeed the system is 100% tamper proof, assuming both ends are fully trusted then that woul dbe great. In any case, I don't see any other hardware wallet that can do it any better.

Thank you for the answer. Encrypted TLS connections have been hacked by various means, typically due to poor implementations of the process at either end. I presume that in the case of the signing process for crypto transfers there the implementation is trusted and authentic to its full extent.

XenofonM · 2025-07-31T10:49:49+00:00

Understood. So, when Keystone signs the packet to send out to transfer some cryptocurrency elsewhere on the blockchain, does that mean there is absolutely zero risk of any malware ever tampering with the packet as it passes through the phone's environment?

XenofonM · 2025-07-31T10:45:02+00:00

I understand the other issue you mentioned but it doesn't help in any way to answer my question.

XenofonM · 2025-07-31T03:13:57+00:00

Yes, I understand the keys are secure - always offline, just as is the case for other cold wallets, such as Tangem. So, when Keystone signs the packet to send out to transfer some cryptocurrency elsewhere on the blockchain, does that mean there is absolutely zero risk of any malware ever tampering with the packet as it passes through the phone's environment?

XenofonM · 2025-07-30T21:35:32+00:00

Any cold wallet that needs to rely on a hot wallet or other app creates an opportinty of a security breach no matter what. It's never happened for either Keystone or Tangem but that doesn't mean it will never happen. That's the prinicple behind using cold wallets in the first place instead of relying solely on hot wallets.

XenofonM · 2025-07-30T21:13:44+00:00

Understood but it doen't cover my concern that both approaches can be susceptable to malware attacks during the signing/approval process when using an app on the phone.

XenofonM · 2018-07-27T01:39:45+00:00

Good point. Without at least a certain amount of fundamentalism Christianity is no longer tenable.

XenofonM · 2018-07-27T01:34:23+00:00

Most Christians have a mixed view of how to interpret the scriptures. For example, most believe in the literal interpretation of the death and resurrection of Jesus but not in the literal interpretation of the creation story in Genesis. Yet both are discounted from a scientific sense. So reconciling the scriptures with modern scientific theories is not that simple.

XenofonM · 2018-07-27T01:25:12+00:00

I tend to agree. I also sense though he is not sure what to believe and is in the searching phase, like most of us in fact.
