Frictionless Wallets, Part 2: Social Login with a 2-of-3 Secret
3 min read
This is part two of a three-part series on making on-chain wallets feel like normal apps. Part one covered device-specific key-pairs - a browser key your main wallet delegates non-financial signing to. Part two answers the next question: where does the main wallet come from in the first place? For most people, "write down 24 words" is where onboarding ends. Social login replaces that with a sign-in they already use - backed by a 2-of-3 secret so no single party ever holds the wallet.
This is a Cardano capability first: the wallet derives a standard Cardano wallet (CIP-1852, payment and stake addresses) alongside EVM and Midnight wallets, all from one identity.
