Losing Seed Phrases Without Losing Funds — Social Recovery Wallet Architecture — Losing Seed Phrases Without Losing Funds
Social recovery replaces the seed phrase backup with a set of trusted "guardians" who can collectively authorize wallet recovery. Vitalik Buterin designed it; Argent deployed it at scale.
