What it is

Crypto assets require different thinking than traditional wealth. We design custody architecture, signer roles, transaction verification rituals, and recovery drills — without ever photographing seed phrases or compromising your cold storage.

Coordination with family office wire procedures and estate planning counsel is standard.

Ideal for: Families with material on-chain holdings or complex signer structures.

What's Included
  • Custody model design (hot / warm / cold)
  • Multi-signature and hardware wallet architecture
  • Signing ceremony and amount-cap protocols
  • Signer redundancy and break-glass drill
  • Family office coordination for large movements
  • Documentation for trustees and counsel

How engagements are delivered

Every engagement starts with what's actually at risk - then fixes what matters most. You receive a clear scope, hands-on remediation where it counts, and documentation your family can act on.

Identified in your Sanctuary Model?

If a private household briefing flagged this lane, this service is how that work is later executed - not another checklist.
