Trezor Shamir Backup (SLIP39)
Bitcoin Inheritance
Trezor's Shamir Backup, implemented on Trezor Model T and Trezor Safe 3/5, uses SLIP39 — an advanced cryptographic secret-sharing scheme — to split a Bitcoin wallet seed into multiple shares distributed among trusted family members or advisors. Unlike the single 24-word seed, Shamir Backup creates a user-defined threshold (e.g., 3-of-5 shares needed) so that no single person can access the wallet or cause loss. It is the most cryptographically robust hardware wallet inheritance mechanism available to consumers.
