Safepal is close source. Its secure element is close source...
All secure elements are closed-source even in open-source hardware wallets. There is no such thing as an open-source, no NDA-having secure element. Not yet at least.
...but the use of passphrase while generating the keys and addresses on the wallet will make this attack impossible because as passphrase is added, new keys and addresses are generated which is different from if only seed phrase is used to generate the keys and addresses.
Not impossible, but harder. The passphrase mitigates the non-fixable hardware vulnerability that Trezor has, but the chosen passphrase has to be complex enough. Using "duck" as your passphrase is easily bruteforceable in contrast to a set of 6-8 English words, for example.
Also, it requires a desktop device to operate and most users use mobile phones to manage their crypto wallets. So it will be better to suggest a wallet that is available on mobile phones also trustworthy. I am using trust wallet since its creation time and I can say it's one of the best multi-wallet for mobile users.
OPs question was which one is the best. A mobile wallet installed on a device that is constantly online and uses all kinds of weird software and games that people download and install these days certainly doesn't fall in that category of one of the best options. Trust Wallet might work OK for you, but it remains a closed-source multi-currency wallet.
I tend to agree, you can have a secure wallet through an air-gapped wallet using your mobile device and never connect to the internet.
It's almost impossible to create a properly airgapped mobile phone. That entails removing all hardware that can establish a connection to the Internet. Mobile phones come with all kinds of antennas and you won't succeed in removing them without breaking the device.
A ledger wallet is also what I've got but not an X version. It's known for having a lot of bugs but I don't know if they get to fix most of those bugs that has been existing on that version.
The new models of the Nano X are terrible and shouldn't be purchased. In the first couple of years, its production was much better than what we see today.
i will buy Ledger Nano X hardware wallet. I show some videos in YouTube about Ledger Nano X. I think it’s perfect for me, and it is easy to use.
I suggest you visit the
hardware wallet section of Bitcointalk and look through the threads created there. Pay attention to how many problems there are with Ledger's Nano X device. If I wanted a new HW tomorrow, it would not be the Nano X.
