Who This Is For

Holders who have accumulated bitcoin over several years and maintain offline archives across multiple devices, steel backups, and written instructions. You may be preparing for a generational handoff, relocating internationally, or simply want an independent assessment before your next hardware refresh.

What We Examine

During a Wallet Archive Review, a senior reviewer at App Brook Field walks through your entire custody chain:

  • Seed phrase backups — material type, duplication strategy, geographic separation, and legibility after years of storage
  • Hardware wallets — device inventory, firmware versions, passphrase (BIP39 extension) handling, and manufacturer support timelines
  • Recovery documentation — written instructions intended for a spouse, executor, or successor, tested for completeness without requiring technical knowledge
  • Multisig and advanced setups — coordinator keys, xpub records, change-address policies, and gap between intended and actual configuration

We do not ask you to reveal seed phrases on camera or transmit them digitally. The review is conducted with you present, examining physical materials and device screens under agreed protocols.

What You Receive

Within ten business days of the session, you receive a bound written report covering:

  1. An inventory summary of reviewed materials (no secret content reproduced)
  2. Identified gaps ranked by severity
  3. Specific remediation steps with estimated effort
  4. A one-page emergency recovery outline suitable for a trusted family member

What Is Excluded

  • We do not move, consolidate, or transact with your bitcoin
  • We do not provide investment or tax guidance (see our Not Financial Advice page)
  • Ongoing monitoring or annual re-reviews require a separate engagement
