Elliot from the Stellar Development Foundation demonstrates how to build passkey-authenticated smart wallets on Stellar using PasskeyKit and LaunchTube, eliminating the need for traditional wallet setup and seed phrases.
Elliot, a developer advocate at the Stellar Development Foundation, presents a comprehensive walkthrough of implementing passkeys for blockchain onboarding. He explains how passkeys, based on the WebAuthn specification and supported natively via SECP256R1 on Stellar protocol 21, eliminate friction in user onboarding by replacing seed phrases and wallet complexity with biometric authentication. The demo builds a guest book dApp using PasskeyKit (developed by Tyler) and LaunchTube, showing how users can sign up, create smart wallets, log in, and interact with smart contracts using only their fingerprint or face ID. The implementation covers signup, login, logout, contract invocation, and token transfers, demonstrating that non-technical users can transact on-chain without understanding blockchain fundamentals.
