Web3Auth
An embedded-wallet SDK using MPC and threshold cryptography to split a key across the user's device, social-login provider, and a Web3Auth share — no single party holds the full key.
Web3Auth (formerly Torus) splits each user's private key into three shares using Shamir secret sharing: one on the user's device, one derived from their social-login provider, and one held by Web3Auth's network. Any two are enough to reconstruct the key; no single party holds the full key.
The model removes seed phrases from the onboarding flow while keeping the key non-custodial. Web3Auth is used by many consumer- focused dApps that want social-login UX without trusting any single custodian.
