FAQ
Do you hold any keys?
No. Plan B Vault is designed for self‑custody; you control the keys.
What happens if a key is lost?
Quorum design and recovery drills ensure continuity; we document recovery paths.
Can we restrict spending by time or amount?
Yes — policies can require delays, multi‑approvals, and per‑day limits.
Does it support inheritance?
Yes — designate beneficiaries and enable time‑locked access with governance steps.
Is it multisig only?
We prioritize multisig for teams; single‑sig flows are available for smaller cases.
