Who each is for

Fit follows the custody model, not the brand. Both platforms here run the same model, so the honest answer is one answer.

Onramp Finance and Arch (Bitcoin-Backed Loans)

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
