OneKey KeyTag is a titanium seed phrase backup solution engineered for maximum durability and portability. Weighing just 14g and smaller than a credit card, it stores up to 24 BIP39 recovery phrase words plus 2 passphrases using numerical index encoding rather than written letters — a compact and tamper-resistant backup method. Built from aerospace-grade TC4 titanium alloy with a melting point of 1,668°C, KeyTag withstands extreme heat, cold, water, and chemical corrosion. Waterproof, acid-resistant, and temperature-proof, it provides long-term physical protection for recovery data associated with any BIP39-compatible hardware wallet.

This is a physical hardware security accessory. It does not provide financial services, trading, exchange, or asset management of any kind.
