Why treasurers call us
Boards need evidence, not wallet access
When a club holds Bitcoin or stablecoins in cold storage, members rightly ask how reserves are verified without exposing private keys. We translate custody practices into dated attestations, transaction summaries, and reconciliation worksheets that non-technical directors can follow.
Our work sits between your wallet setup and your annual meeting — documentation that stands on its own when auditors or new members review the books.

Client notes
What treasurers report after delivery
Our Seoul investment circle had twelve members asking the same question every quarter: prove the cold wallet still holds what we think. Panel Birch Core produced a binder our chair could walk through in twenty minutes, with redacted transaction logs I could actually follow.— Min-jun K., treasurer, private investment club, Seoul
The documentation was thorough, though I wish we had started the intake earlier — gathering two years of signing records took longer than expected. Still, the final attestation package satisfied our external reviewer.— Hye-jin L., board secretary, Daegu alumni association fund
