Key questions to ask vendors

To make sure they truly fit your use case, ask:

1. How is wallet segregation implemented?

   • Per-client, per-entity, per-subaccount, or per-policy?

2. What cold storage workflow do you support?

   • Air-gapped signing? Offline approval? Geographic separation?

3. How are approvals enforced?

   • M-of-N, dual control, threshold policies, human approvals?

4. Can keys be separated by legal entity or jurisdiction?

5. What audit logs and exportable records are available?

6. Do you support insurance, SLAs, and SOC 2 / ISO 27001?

7. Can we customize withdrawal limits, whitelists, and time delays?
