Client Stories
Testimonials and assembly case notes from cold wallet holders
Testimonials
"I had three years of Ledger exports sitting in a folder my accountant refused to open. Cedarcore turned them into one CSV with fee columns my preparer actually used. The intake call was longer than I expected, but they asked the right questions about wallet migrations."
"Margaret's case was messier — paper notes from 2018 and a Trezor I had wiped before exporting. They recovered most of it through on-chain tracing, though two small transfers stayed unresolved. Honest about what they could not prove."
"The review session caught a labeling issue where I had marked exchange deposits as internal transfers. Saved me a back-and-forth with my tax office. Straightforward memo, no jargon."
"Response times slowed during the last week before filing — understandable given volume. Final logs arrived two days later than quoted, but the quality held up."
Case note: Multi-wallet migration year
Client: Holder with assets across Ledger Nano S, a paper backup wallet, and a one-time air-gapped setup from 2019.
Challenge: Device wipe in 2021 without full export; paper notes with approximate dates only.
Assembly: Analysts traced on-chain movements between derived addresses, matched paper note dates to nearest confirmed blocks, and flagged three transfers where date precision could not exceed ±48 hours.
Outcome: Filing-ready reference log with an appendix documenting unresolved ambiguities. Accountant accepted the package with two follow-up questions resolved in the included revision round.
Engagement: Cold Wallet Log Assembly, 4-week timeline, ₩620,000 final scope.
Case note: Expatriate dual-context filing
Client: U.S. citizen residing in Incheon with cold storage only — no exchange accounts.
Challenge: Needed reference logs formatted for both South Korean local filing support and U.S. preparer import requirements.
Assembly: Parallel CSV structures with consistent transaction IDs, separate fee notation columns per jurisdiction’s common expectations.
Outcome: Both preparers accepted documentation without requesting reformatting. Client has returned annually since 2022.
