BitHarbour was architected from the ground up with one principle: your Bitcoin must be secured to the highest standard known to cryptography — without compromising your sovereignty.
Each layer is independently hardened. A breach at one level cannot compromise the others.
Private keys are generated and stored in an offline, air-gapped environment. They never touch the internet — ever. Even during transaction signing, keys remain isolated on your device.
Configure 2-of-3 or 3-of-5 multi-signature schemes. Distribute keys across different devices, locations, or trusted parties. No single compromise can move your Bitcoin.
All data — at rest and in transit — is encrypted with AES-256 in GCM mode, providing both confidentiality and authenticated integrity. Backups are encrypted client-side before leaving your device.
Industry-standard 12 or 24-word seed phrases with optional BIP-39 passphrase support. Add a 13th or 25th word — known only to you — that even brute force cannot crack.
Route all wallet traffic through the Tor network. Your IP address, location, and transaction patterns are obfuscated from network observers and blockchain surveillance.
BitHarbour never holds, sees, or has any access to your private keys. Your wallet is generated client-side and the keys remain exclusively on your device. If our servers disappear tomorrow, your Bitcoin is still yours.
Our core wallet code is open source and independently auditable. Trust, but verify — you can inspect every cryptographic operation and build from source yourself.
We collect zero personal information. No name, no email, no phone, no KYC. The platform works without an account. Your financial privacy is absolute.
BitHarbour seamlessly integrates with leading hardware wallets for the ultimate air-gapped security setup.
