Sama-sama merupakan wallet yang mengusung fitur air-gapped, dan masing-masing punya kelebihan dan kekurangan.
Dari artikel yang saya baca di-quote berikut, setidaknya ada beberapa poin yang mungkin perlu diperhatikan kalau mau 'main-main' dengan SafePal S1 dan mungkin ini masih bisa di-improve oleh developer pada rilis firmware/hardware versi berikutnya:
-Despite all the security measures, SafePal doesn’t provide an option to bail out of a duress (gunpoint!) situation. Support for BIP39 passphrase is an important feature that’s missing at the moment.
-Even though SafePal supports a large number of ERC20 tokens, currently it doesn’t have the option to add custom ERC20 tokens and you can only add the ones that are available on the pre-defined list of supported tokens.
-Since SafePal is closed-source, there’s no way to verify whether its hardware wallet uses a TRNG to generate the mnemonic phrase. Getting some random input from the user (e.g., taking multiple images using the on-device camera) would introduce an external entropy factor which would be unique for all users. Thus, the trust factor could be reduced.
