Metal Seed Backups

Metal seed backups are physical storage devices, typically made of stainless steel or titanium, designed to protect cryptocurrency recovery phrases from environmental damage. Unlike paper backups, which are susceptible to fire, water, mold, and physical degradation, metal plates provide a durable medium to engrave or punch the 12 to 24-word seed phrase.

These backups are critical for long-term cold storage security, ensuring that a user can restore access to their digital assets even if their primary hardware wallet is lost or destroyed. By utilizing high-melting-point materials, these tools offer a robust defense against catastrophic physical loss.

They serve as a foundational security measure for self-custody, mitigating the risk of single-point failure in hardware storage. Users must store these physical backups in secure, fireproof, and hidden locations to maintain the integrity of their asset protection strategy.

This method aligns with the principle of offline, immutable data preservation essential for high-value asset management.
