The most secure Bitcoin wallet
For enhanced security, your funds are secured on the bitcoin network with two physically separated keys.
A master key is the only thing that needs to be backed up, no matter how many Bitcoin addresses get generated from it.
Yubikey, Google Authenticator, or SMS can be used to further secure funds against unauthorized access.
All our technology is fully open sourced. You can review the code and run it on your own hardware.
We are a vault for keys, and we cannot spend your bitcoins, even if we wanted to.
You set the conditions required to spend your funds e.g. you can set daily, weekly or monthly withdrawal limits.
