Summary

This milestone delivers the core components required to support Interstellar’s secure Web3 account framework, developed as part of the testnet initiative. These components enable passwordless onboarding, secure authentication, attested transaction validation, and multi-option recovery for mobile-first users, leveraging a decentralized Substrate-based architecture.

The system’s core capabilities—such as instant user onboarding, trusted SE-based authentication, secure cloud backup via garbled circuits, and mobile-friendly recovery via NFC—are implemented through the combination of custom Substrate pallets and mobile-side logic. All features are aligned with regulatory-grade standards, such as DSP-SCA, and WebAuthn/FIDO2 while maintaining a decentralized and privacy-preserving design.

The architecture has been designed to scale across mobile apps, wallet SDK integrations, and dApps, offering a unified framework for secure account abstraction and transaction control.
