Full custody review

Who this is for

Investors who keep the majority of their crypto on hardware wallets and refuse exchange or portfolio dashboards as a source of truth. Typical clients hold two or more devices, may share signing duties with a family member, and want a calm, written picture of what each device has done lately.

What you walk away with

• A device-by-device activity log reconstructed from on-device history, receive addresses you provide, and your own paper records
• A custody notes packet (printed, not emailed) covering device models, firmware versions observed, passphrase use (yes/no only—never the phrase), and backup locations you disclose
• A short list of inconsistencies or forgotten test sends found during the session
• Clear exclusions so you know what we did not verify (for example, exchange accounts you intentionally leave out)

What is included

We work only with the hardware you bring into the room. The session covers unlocking under your control, reviewing transaction history available on-device or via a local viewer you already trust, photographing device labels for your packet (with your consent), and drafting custody notes you keep offline.

What is excluded

We do not take custody of coins, store seed phrases, sync wallets to our systems, or operate as a broker. We do not rebuild lost recovery phrases. Legal opinions on tax or inheritance are outside scope; we can refer Seoul counsel when asked.

Provider and process

A CognitiSec reviewer leads the session. You remain the only person who enters PINs or passphrases. We follow a fixed sequence: intake inventory → per-device activity logging → cross-check against your notes → custody packet review → questions. See the engagement page for timing and preparation.

Duration, place, preparation

Most reviews finish in two to four hours depending on device count. Sessions run at our Gangnam address or a private room you arrange nearby. Bring every device in scope, any metal or paper backups you are willing to discuss (not to photograph unless you ask), and a rough timeline of large moves since your last self-check.

Pricing basis

Sessions start at ₩850,000 for up to three devices. Additional devices and multi-day family handovers are quoted after a short intake call. Rates are informational; no payment is taken on this site.
