About NeuralTechs
A Seoul practice built around quiet rooms, offline devices, and the paperwork habits that keep self-custody trustworthy.
Why we exist
Self-custody fails less often from exotic attacks than from messy habits: unsigned firmware notes, unlabeled PSBT folders, and travel bags that carry every device at once. NeuralTechs formed in Seoul to give experienced holders a place to pressure-test those habits without surrendering keys.
Origin
The practice began after years of informal peer reviews among holders who met in quiet cafés near Guro Digital Complex. Those sessions needed a proper room, clearer boundaries, and written memos clients could file beside their metal backups. NeuralTechs is that room.
How we work
Sessions are appointment-only. We keep guest Wi-Fi physically switched off in the audit suite. Notes leave as paper or encrypted offline files you control. If a request would require seeing a seed phrase, we end the conversation.
People
Our facilitators come from operational security backgrounds and long personal use of hardware wallets—not from retail brokerage desks. We speak English for international clients and Korean when preferred; memos can be delivered in either language.
Values
- Physical control stays yours. Devices never leave your hands for “just a minute.”
- Paper before spectacle. Logging discipline beats dramatic threat demos.
- Honest limits. If a question is legal or tax-shaped, we say so and stop.
Community
We occasionally host small evening roundtables on signing-log formats for holders already comfortable with air-gapped workflows. These are not onboarding classes. Seats are limited and announced by email to past clients first.
