Stamp Seed’s Titanium Shamir Backup Plates are designed for securing SLIP39 Shamir Backup shares, giving you a more flexible way to protect your Bitcoin wallet recovery.
Instead of relying on one single recovery phrase, Shamir Backup allows you to create multiple recovery word lists, called shares, and set a minimum number required to restore access. For example, you may create 3 shares and require any 2 of them to recover your wallet. This helps reduce the risk of a single backup being lost, stolen, or damaged.
Each Stamp Seed Shamir Plate gives you a durable, offline way to store one Shamir Backup share in solid titanium. Use multiple plates to separate and store your shares in different secure locations, creating a backup setup that is resilient, private, and completely offline.
Built from commercial-grade titanium, each plate is made to withstand extreme conditions while keeping your recovery information legible and protected for the long term. Titanium’s natural oxide layer helps defend against moisture, saltwater, acids, and rust, while the solid single-piece design eliminates fragile tiles, rivets, screws, or moving parts.
