The challenge
Self-custody has no answer for what happens when the holder does not come back. A seed phrase kept properly — offline, private, known to nobody — is also a seed phrase nobody can recover, and everything behind it goes with it.
What it does
sBox keeps passwords, seed phrases and documents encrypted, and adds a nominee layer above them: the holder names who should inherit access, and the product releases it under defined conditions rather than leaving it to a note in a drawer. Setup runs in under five minutes, and a free tier means the recovery path can be tested before anything valuable goes in.
See it for yourself. Serenity is live and open to anyone — nothing on this page is a mockup.
