NeuralTechs
Air-gapped wallet audits for people who already hold their own keys.
Private sessions in Seoul that walk through device hygiene, signing-log order, and the quiet habits that keep self-custody intact.

NeuralTechs runs focused, offline-first audit sessions—not software access. You bring the devices you trust; we bring a structured review of how those devices talk to the outside world.
Flagship session
Air-Gapped Wallet Audit
A three-hour private review covering firmware provenance, passphrase handling, destination address verification habits, and a written signing-log map you can keep offline.
Session detailsRelated work we take on
Supporting sessions that sit beside the flagship audit when your custody setup has grown beyond a single device.
Air-Gapped Wallet Audit
A structured three-hour review of firmware provenance, passphrase habits, address verification, and offline signing discipline.
Multi-Device Custody Review
Map roles across several hardware wallets, passphrases, and geographic storage so no single travel bag holds the whole story.
Signing-Log Organization
Rebuild the paper or offline digital trail that records what you signed, when, and against which policy—without exposing keys.
“They spent almost forty minutes just on how I labeled PSBT exports. Tedious—and exactly what I needed before rotating a cold vault.”
— Min-jae K., multi-device holder, Gangnam
