The Seed Phrase Companion (SPC) is available.
Every bitcoiner knows the rule: never share your seed phrase.
But there's another side to self-custody that gets much less attention.
What information can someone safely know about your setup?
Which wallets exist.
Which devices are still relevant.
Whether multisig is involved.
Who is allowed to help.
And what nobody should ever ask to see.
That information isn't a substitute for your keys. It's the context that helps prevent confusion and dangerous mistakes.
That's why I created SPC.
A digital Bitcoin continuity workbook for organizing the non-secret side of self-custody.
Keep the secrets private. Make the safe instructions understandable.
21k sats. DM for a private invoice.
