Client Reviews
Accounts from families who completed multisig device register setup and offline wallet tracking consultations with App Grove Field.
Extended Account: The Han Family Register
The Han family held a three-of-five multisig reserve across signers in Seoul, Busan, and Vancouver. When their father updated firmware on two Ledger devices without coordinating with siblings, derivation paths diverged and a test transaction failed.
They engaged App Grove Field for a full device registration. During session one, we discovered one signer had been using a non-standard BIP84 path. The register documented the correct paths, and session two included a coordinated firmware rollback and re-verification.
Six months later, when their father passed, the register allowed the remaining four signers to complete a recovery transaction within forty-eight hours. The family noted that the written procedure section — written for non-technical readers — was what their mother relied on most.
Testimonials
After our father passed, we discovered his Ledger had a different passphrase than we remembered. The register App Grove Field helped us build two years earlier listed every derivation path and the exact recovery phrase location. Without that document, three of five siblings would still be locked out.— Min-jun H., three-of-five family multisig, Gangnam
The key ceremony felt thorough, though I wish we had scheduled a follow-up sooner — six months passed before we verified our first offline balance check. Still, the written register has already prevented one firmware-update mistake.— Sarah L., two-of-three reserve wallet, Itaewon
We came in thinking we just needed someone to write down our wallet models. The audit revealed our fourth signer had never actually tested their recovery phrase. That alone justified the session cost, even before the full registration.— Thomas and Yuna R., four-of-six family trust, Seongnam
The documentation quality is excellent. My only hesitation was the price for our relatively simple two-of-three setup — we probably could have done a shorter engagement. But the bound register sits in our safe deposit box now, and that permanence matters.— James K., two-of-three reserve, Hannam-dong
Remote signers in London and Sydney joined via video. Coordination took longer than expected, but every participant confirmed their section of the register independently. The geographic distribution map in the document is something we reference quarterly.— Patricia M., three-of-five international family, Seocho
Project Evidence
Families receive a bound register document upon completion. While we cannot share client registers publicly, the structure includes: device inventory tables, signer responsibility matrices, derivation path records, xpub fingerprint verification logs, and plain-language recovery procedures.
