I want to buy a Keystone, just for use with Metamask and to store altcoins, like ETH, Sol, USDT, USDC.
Considering that they only communicate through QR codes, and the firmware of Keystone and the Metamask app are both open-source, and come from different companies, wouldn't that make it more secure?
It would make it safer to use that way..
Thanks for your suggestions.
...but I just never liked Metamask wallet and I don't care much about ethereum and all it's tokens, but Rabby.io wallet is much better eth alternative for metamask.
Watch out for Keystone wallet battery, you have to charge it on regular basis or it could stop working and die, this is the weak spot of new Keystone 3 devices, and it's not easy to replace batteries like in older version.
In the Google Store, Metamask has been downloaded 10 million times, while Rabby has been downloaded 100,000 times.
I may use hardware wallets very rarely, and the battery will die. At that time, it should be charged through a USB cable.
