What our users say

EK Han

"Usually, the mnemonic key is stored in the phone notepad. If I lose my entire cell phone, it will be useless, so I was wondering where to write this down for safety. I think it's really comfortable that you don't even have to write it down in the first place."

Jeny Kim

"Storing the mnemonic key in the cloud, or leaving my key intact, no matter how large a company is, was a bit anxious, but I can trust that it is key encryption and distributed storage."

Anonymous user

"If I lose my paper or USB that contains mnemonic or change my phone, I will use it as a last resort"

Allen Choi

" The subscription fee is quite reasonable for protecting all wallets I have. I use 7 wallets. It's been hard to manage all."

David H Wong

" It's like an insurance for all my assets."
