ZKsync has announced the launch of its Smart Sign-On (SSO) feature, designed to enhance user experience by enabling walletless interactions and simplified transaction processing for Web3 applications. This new toolkit aims to address the challenges of fragmented onboarding processes, particularly for users unfamiliar with Web3 technology.
The ZKsync SSO offers a Web2-like user experience by integrating session management, allowing users to log in using biometrics such as FaceID. This eliminates the need for creating seed phrases, while users maintain control over their private keys. The session key feature enables users or applications to sign transactions within pre-approved rules, reducing the need for repeated transaction approvals.
Key Features and Developer Tools
The ZKsync SSO is built on the ERC-7579 standard, providing modular smart accounts that support passkey authentication and session management. Developers can integrate the SSO into their applications with minimal code using the provided SDK, which is compatible with most onboarding libraries. This integration aims to improve user retention by allowing users to authenticate once and approve a temporary session for transaction signing.
The system is wallet-agnostic, open-sourced, and backed by self-custody, ensuring security and transparency. The SSO consists of three main components: the Developer SDK, Auth Server, and Smart Contracts. The Developer SDK simplifies integration, while the Auth Server manages authentication processes. Smart Contracts handle account management and session enforcement.
Future Developments and Enterprise Solutions
ZKsync plans to enhance the SSO with additional features such as recovery options and multifactor approvals to bolster security. The company is also developing solutions for enterprises, including an embedded wallet SDK that allows self-custodial on-chain accounts without redirecting to an authentication server. This aims to streamline operations and enhance security within enterprise applications.
Developers and users can explore the ZKsync SSO on the testnet, with a mainnet release planned following an external audit. More details and a demo are available here.
