Annual Custody Reviews: What Changes and What Stays
A guide to yearly reconciliation of custody records for private treasuries with offline wallet holdings.
An annual custody review is not a repeat of the initial ledger preparation. It is a reconciliation exercise: comparing what your documentation says against what your treasury actually does.
Common changes we find
Signer roster drift. A director who was a signer has moved to a non-signing role. A new finance team member was added to the multisig without updating the matrix. Contact information for remote signers is outdated.
Storage relocation. A vault box moved from one branch to another. A home safe was replaced. The ledger still references the old location.
Device lifecycle. Hardware wallets decommissioned but still listed as active. New devices purchased but not yet added to the inventory. Firmware updates that changed device identifiers.
Procedure gaps. Recovery contacts listed in the ledger have left the organization. The escalation path documented twelve months ago no longer matches current practice.
The review process
We request an updated inventory submission from your treasury lead, conduct brief interviews with any new signers, and compare the current state against your existing ledger. The deliverable is an updated ledger section plus a gap analysis memorandum highlighting discrepancies and recommended corrections.
When to review more frequently
Schedule an interim review after any of these events:
- A signatory departure or role change
- Addition of a new wallet or multisig participant
- Relocation of seed storage materials
- An external audit finding related to custody documentation
- A merger or restructuring affecting treasury governance
Annual reviews are the baseline. Event-driven updates prevent small drift from becoming an audit crisis.
