definition
Shamir's Secret Sharing splits a secret (like a seed) into N shares such that any M shares can reconstruct it, but fewer reveal nothing. Some wallets implement a standardized variant (SLIP-0039).

caution
- Poor storage of shares can still leak the secret
- Consider multisig + distributed backups as an alternative
- Practice recovery to avoid misconfiguration
