Problem Statement

The project aims to onboard millions of users on-chain, seamlessly and create an avatar for them, fully customisable and extendable.Webauthn is already available in every browser, including mobile ones like iOS Safari! Which means this approach will not need an approval from Apple, it's already on every iOS device. Users can start onboarding today!Every time user need to transfer something from the Smart Account, they need to do FaceID/Fingerprint verification and that's all 🤯

Solution

Excited to share details. Multiple interesting technologies are used here in combination. Webauthn (FaceID/Fingerprint auth), Account Abstraction (ERC-4337) and Paymaster. For users the experience is the same as web2. However, all assets are on-chain and only user can unlock account with FaceID, Fingerprint or YubiKey.Let's dive into details! Webauthn is used for Private/public key pair generation. Private key is stored on the user's device and even user can't read it. The only operation user can do is to unlock it by FaceId/Fingerprint and sign transaction.Webauthn is available in all major browsers, including mobile, Android/iOS, which means there is no need of application approval from authorities like Apple, Google to onboard users to web3 with this approach.
