The configuration ladder

The major self-custody setups arrange themselves into a ladder of rising complexity. Each rung solves a real problem — and introduces new ways to fail.

How to use it

Don’t ask “what’s the most secure setup?” Ask “what’s the simplest setup that adequately covers the risks I can actually name?” Find that rung, build it, test it — and don’t climb higher until a real reason pushes you up. Complexity you don’t fully control is itself a threat.

  1. 1 Single-signature hardware wallet One device, one seed, one backup. The simplest self-custody that isn’t negligent. Most newcomers · modest stack relative to net worth
  2. 2 Single-sig + BIP-39 passphrase Add a secret “25th word.” The seed alone opens a decoy; seed + passphrase opens the real wallet. Holders worried about seed-phrase exposure or coercion
  3. 3 SLIP-39 / Shamir backup Split the backup into shares — any M of N reconstruct it. No single share reveals the seed. Holders who want split backups without running multisig
  4. 4 DIY 2-of-3 multisig Three keys, any two sign. No single key — lost or stolen — can move or lose your coins. Substantial, hands-on holders willing to learn the tooling
  5. 5 Collaborative 2-of-3 multisig You hold two keys; a service holds the third — for signing help and inheritance, not custody. Inheritance-minded holders who want a professional safety net
  6. 6 3-of-5 multisig Five keys, any three sign. Maximum resilience — and maximum complexity. A small minority: large holdings, distributed trustees, real institutional needs

Reading the ladder

BIP-85 — the orthogonal simplifier

BIP-85 sits beside the ladder rather than on it: it derives many child seeds from one master, cutting how many backups you keep. Useful at any rung — but it concentrates failure on that one master, which must then be protected at the level of everything derived from it.

Where do you belong?

Three questions decide almost everything: how much are you protecting, who needs access if you die or are hurt, and what worries you most — losing it, getting hacked, or being coerced. A guided tool that turns those answers into a single recommendation is coming next; for now, the reading above places most people correctly.
