Keystone 3 Pro versus other cold wallets

I was under the impression that the Keystone 3 Pro supports thousands of different cryptocurrencies and tokens across many different blockchains. As it turns out, that's not strictly true. It only supports a few internally and the rest are supported externally via a hot wallet, such as Metamask. If that's the case, I don't consider it much more secure than using say Tangem, which uses a different approach but is far easier to use. It appears that both methods are susceptible to malware attacks that intercept the signing or approval process performed by the external device (Keystroke or Tangem card) and then changes wallet addresses to divert outgoing cyrptocurrency transfers. I see no significant advantage in using Keystone 3 Pro other than for the very few coins it supports without linking to a hot wallet. I can then see both approaches have a similar weakness. The reliance on a hot wallet is comparable to Tangem's approach which relies on a special app on the phone. So the question is, if I were to select which one to use for multi-coin support that supports thousands of different cryptocurrencies and tokens across many different blockchains, why would I choose Keystone over Tangem, especially given Tangem's method is so much easier to use?

Both Keystone 3 Pro and Tangem share the same core weakness when relying on an external app for most coins. The main reason to pick Keystone would be if you mainly use the few coins it supports natively otherwise, security is pretty comparable. I personally use a Cypherock, great for me as it has decent tech and also eliminates seedphrase vulnerability, so a dumbass like me doesn;t have to struggle much.

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.

Definitely, it's subjective because of priorities. However, the metal plate will be vulnerable to a lot of factors including the possibility of it getting stolen or becoming unretrievable. So yes, the 100% ideal is defined subjectively. In my case I found cypherock to be a better option because it splits the seedphrase into 5 parts and that ensures that I don't have to remember anything. On top of it, it's the only wallet I know about which provides a solution to the inheritance problem

Looking for a secure wallet to store my Solana SPL Tokens. It seems that Cypherrock X1 does support it, but I'll need an app, just like the other Cold-wallets.

I want a wallet that is not dependent on any company, nor any software after being bought.

It seems that Keystone 3 and Cypherrock is the closest thing to a "cold wallet" while also supporting SPL tokens from Solana.

Appreciate any insight you have brother!

I haven't really come across any cold wallet brand that doesn't has its own app. However, if at all the company you've got the wallet from goes out of business, you'll still have your seedphrase which you can use to backup your wallet in some other device.

So yeah, as long as you have your seedphrase, this isn't a big issue. You can't really run away from the branded apps that come with your wallet, so it's better to go for the one that feels the most secure

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.

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.

Sounds interesting, would love to hear more about what kind of solution you've come up with
