Product Information
Overview
OneKey SeedCard is an encrypted recovery phrase backup card. One tap seals it inside the chip. Another brings it back to your wallet. Never in plaintext.
How It Works
Back up
Choose Back up, hold the SeedCard to your device and set a card PIN. Your recovery phrase is encrypted and written to the card's chip.
Restore
Choose Restore, tap the card again and enter the PIN. Your recovery phrase is imported straight into your wallet.
Features
No plaintext, ever
Backup and restore happen entirely between the card and your device — nothing goes to the cloud or through anyone's hands.
Nothing printed on the card
The chip stores only encrypted data, so no plaintext can be read from it.
Split across cards
Each card has its own PIN — keep one with you and another off-site.
Auto-wipe
Enter the wrong PIN 10 times in a row and the data is erased automatically (optional).
Flagship secure element
CC EAL6+ certified; firmware must pass the manufacturer's signature check to prevent tampering.
