Abstract

This study proposes a novel model to address the security, usability, and scalability challenges of cryptocurrency wallets. The model is implemented as a web application that combines FIDO2 (Fast Identity Online v2) with Account Abstraction (AA), offering enhanced security by storing private keys within the Trusted Execution Environment (TEE) of users' mobile devices. By utilizing two types of private keys, the model supports three account types, allowing users to flexibly select security levels and functionalities according to their needs. The research findings show that the proposed model provides strong security against various attack scenarios while also improving usability and scalability. By integrating hardware wallet-level security with the convenience of software wallets, this new paradigm for cryptocurrency wallets is expected to contribute to the widespread adoption of blockchain technology
