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
Sygnum

Qualified custodian

A regulated institution holds keys in segregated accounts under a legal framework built for it.

A good fit for
  • Entities that must satisfy a regulator, an auditor, or an investment-committee mandate
  • Holders who want institutional process — SOC audits, segregation, named accountability — and accept institutional control
  • Estates and trusts whose lawyers need a counterparty that courts already understand
The wrong choice for
  • Anyone whose core requirement is that no single institution can move the coins — one institution can
  • Privacy-focused holders: the custodian, its regulator, and its subpoena inbox all know your position
  • Small balances: minimums and fees are built for institutions
