Client Records
Testimonials and documented outcomes from small businesses that used Content Haven Hub for bitcoin reserve ledger audits and controls.
What clients report
Our import brokerage had three hardware wallets and a paper backup in a safety deposit box, but no single document explained which wallet corresponded to which ledger line. Content Haven Hub produced a custody map in two sessions. The accountant finally stopped asking us to "just check the blockchain" during quarterly closes.
The controls manual they wrote actually matched how we operate—not some idealised procedure nobody would follow. Our external auditor accepted the documentation without requesting a second round of questions. I wish we had done this before our first bitcoin audit, not after.
Monthly reconciliation sessions caught a mislabelled wallet address that had been sitting in our spreadsheet for eight months. The variance was small, but the accountant cared about the principle. Sessions are efficient—90 minutes and we leave with a signed sheet.
They were thorough on the audit itself, though the report delivery took six business days instead of the five they quoted. Kim called to explain the delay caused by a multisig mapping complication. The extra day did not matter for our timeline, but I would have appreciated knowing sooner.
Extended record: Bundang trading firm custody mapping
Client: Import brokerage, 12 employees, Bundang-gu
Situation: Three Ledger devices acquired between 2021 and 2023, one paper seed backup in a bank safety deposit box, spreadsheet ledger maintained by operations director. No reconciliation had been attempted. External accountant flagged the bitcoin line item during 2024 year-end close.
Engagement: Wallet Custody Mapping (half day) followed by Reserve Ledger Audit (two days)
Outcome: Custody diagram linked each device to ledger rows. Audit identified one wallet with ₩0 variance and two with minor timing differences explained by pending confirmations. Controls gap analysis recommended separating backup verification from daily operations—a change the client implemented within two weeks.
Follow-up: Client enrolled in monthly reconciliation sessions starting March 2025.
Extended record: Seongnam consulting partnership controls documentation
Client: Professional partnership, 6 partners, Seongnam
Situation: Partnership held bitcoin reserves across two Trezor devices with a 2-of-3 multisig arrangement involving one external advisor. Partners disagreed on withdrawal approval steps. External auditor requested written controls before signing off on reserve valuation.
Engagement: Controls Documentation with one review session
Outcome: Controls manual defined withdrawal thresholds, approval sequence, and advisor role boundaries. All six partners signed the acknowledgment page. External auditor accepted documentation without supplemental requests.
Note: Client chose not to enrol in monthly reconciliation, citing infrequent reserve movements. They scheduled an annual re-audit instead.
