What Clients Report

They found that my second passphrase copy was stored in the same physical location as my hardware wallet — a detail I had rationalised away for years. The written report gave my family clear steps without exposing any secrets.
— K.H., Wallet Archive Review, Bundang · 2024
The session ran longer than quoted because my multisig setup had an undocumented change from 2021. I appreciated the thoroughness, though the follow-up summary took an extra week to arrive.

My wife can now locate every piece of the archive without calling me. The documentation review was worth it for peace of mind alone, even if the suggested revisions felt pedantic at times.
— R.T., Recovery Documentation Review, Itaewon · 2023
I was sceptical about paying for someone to look at papers I already had organised. They identified that one of my steel plates had corroded along a single character groove — invisible until they held it at an angle under the desk lamp.

Extended Account: The Han Family Archive

Situation: A couple in their sixties holding bitcoin since 2016 across three hardware wallets and two steel backups. Preparing for their son to assume custodial knowledge.

Engagement: Full Wallet Archive Review over two half-day sessions (scope expanded after discovery of a fourth passphrase variant).

Findings: Steel backups were geographically separated but one envelope contained a sticky note with a partial passphrase hint. Recovery document referenced a device model no longer manufactured, with no migration notes.

Outcome: Revised documentation package, recommended device refresh timeline, and a sealed “executor envelope” protocol the family now maintains. Son attended the final hour of the second session.

Client note: “We should have done this three years ago when the setup was simpler.”
