Breek sdk powers many bitcoin wallets. They are rolling out a way to store seed phares that is identical to how we already storing nostr keys at https://44billion.net
They use a client-side passkeys flow so that you don't have to remember your seed, although you may export it at anytime.
However, we went a step further to make sure we can never steal your keys even if we wanted to. The vault (login module) is on a separate domain we don't control. By default it is on Github Pages. You may point to your own fork there or to your self hosted version anywhere by changing the url on the settings page!
