Who each is for

Fit follows the custody model, not the brand.

Unchained

Collaborative multisig

You hold most keys, the provider holds one, and no single party can move funds alone.

A good fit for
  • Technical-enough holders who want real control with a safety net — comfortable with hardware wallets, firmware updates, and a signing ceremony
  • People whose main fear is their own single point of failure: one lost device no longer means lost coins
  • Holders who want to verify rather than trust: the quorum is inspectable on-chain
The wrong choice for
  • The non-technical spouse, parent, or heir who will one day hold this alone — if they cannot run a signing ceremony, the arrangement quietly becomes single-provider custody the day you are gone
  • Anyone who will not maintain it: devices need firmware, backups need checking, and vendor diversity is your job, not the provider's
  • Holders under physical-security threat: keys at home mean the threat model includes your address
Circle (USDC)

Multi-institution custody

Separate institutions each hold a key under their own ceremony; no one of them can move funds.

A good fit for
  • Holders who want independence to be structural rather than a personal discipline — the separation survives your attention span, your health, and your heirs
  • The person planning for a non-technical survivor: the heir works with institutions and documents, not devices and dice
  • Advisors, trusts, and family offices that need no-single-point-of-failure custody they can explain to a fiduciary
The wrong choice for
  • Holders whose definition of bitcoin includes holding a key personally — you do not hold one, and no amount of structure changes that
  • Small balances: institutional fee floors make no sense under six figures
  • Privacy maximalists: multiple regulated institutions know the position
  • Anyone who wants to be able to move coins alone at 2am — the design goal is precisely that nobody can
