Lifetime seed phrase protection Encrypted, offline, and independent of any company.
Your hardware wallet secures spending. MyColdKey secures recovery.
🛡️ How MyColdKey Works
Encrypt — Create one encrypted recovery artifact. Finding it reveals nothing without your password.
Store — Distribute protected copies across multiple locations — without increasing plaintext exposure.
Recover — Restore through multiple offline paths, with just your encrypted backup and password.
One encrypted artifact — use it as a QR, a file, engraved metal, or Shamir shares.
Same backup, your choice of medium. If someone finds it, they still need your password. Nothing readable is left exposed.
Encrypted output — nothing readable without your password.
Multiple copies. Any location. Discovery reveals nothing.
Offline Recovery Kit included — no app install required.
One encrypted recovery design — multiple formats, multiple locations, multiple offline paths.
Recovery stays offline and vendor-independent. No future company required.
Why MyColdKey
Built for serious self-custody: hardened crypto on your machine, recovery that outlasts any software company.
Sovereign Recovery
Multiple offline recovery paths — decrypt in the app, from a backup file, QR, or pasted text, or use a Self-Contained Recovery Kit you export once (no fresh install required). No servers or login needed to recover; the kit still works even if we no longer exist.
Your Recovery, Your Way
Multiple formats — QR, file, text, or Shamir shares. Distribute encrypted copies across multiple locations. Each copy stays encrypted. Discovery reveals nothing.
Hardened encryption, local by design
Argon2id and AES-256-GCM protect your backups; keys stay in RAM and are zeroized after use. Runs locally on your device; Sovereign Mode (Pro) can block server access when you want tighter isolation. Security & Trust →
