1. Preface

The evolution of global digital infrastructure is driving wearable devices beyond their role as simple health monitors into intelligent terminals with enhanced interactivity and data processing capabilities. According to a Statista report, the global wearable device market reached $74 billion in 2024 and is projected to surpass $120 billion by 2028. Among these, smartwatches, as the most representative form factor, account for over half of the market share and have gradually expanded into diverse scenarios such as fitness management, sleep tracking, and daily reminders. However, mainstream products still exhibit significant homogeneity in functionality, data management, and intelligence, struggling to meet growing user expectations for data autonomy, secure payments, and deeply personalized services.

The rise of Web3 is reshaping the relationship between users and data. With the maturation of foundational modules like on-chain identity, encrypted payments, and privacy computing, users now have the opportunity to truly own their data and unlock its value within an open, transparent, and user-controlled framework. According to the latest data from Crypto.com, the global cryptocurrency user base surpassed 600 million by early 2025, with mobile wallet usage continuing to rise. Crypto payments and on-chain interactions are becoming mainstream behaviors, yet these functionalities remain confined to mobile apps or browser extensions, lacking a truly secure, convenient, and habit-aligned physical terminal.

In the AI domain, the rapid advancement of generative artificial intelligence is driving model capabilities toward edge devices. With ongoing optimizations in edge computing and lightweight models, features like personalized health analysis, real-time behavior prediction, and intelligent suggestion generation are gradually migrating from the cloud to local devices, equipping terminals with "perception + comprehension + decision-making" capabilities. This shift suggests that smart wearables should no longer be mere data collection tools but active participants in users' lives as intelligent agents.

However, the design philosophy of current smartwatches remains rooted in the centralized era. Data is stored in closed systems, leaving users with no control over its flow or any means to benefit from it. Devices lack support for on-chain identities and assets, failing to meet user needs in a decentralized world. AI services also heavily rely on cloud-based delivery, lacking truly private, personalized, and real-time intelligent experiences.

Against this backdrop, we introduce VitaWatch, a Web3 smartwatch for the future. VitaWatch integrates a multi-chain encrypted payment stack, enabling users to manage and transact on-chain assets securely and conveniently. It establishes a data autonomy framework, empowering users to govern and monetize their health and behavioral data while preserving privacy. Additionally, VitaWatch features a proprietary AI model with on-device inference capabilities, delivering real-time health analysis, personalized recommendations, and extensible AI Agent services. As an innovative terminal merging Web3 capabilities with AI intelligence, VitaWatch is dedicated to becoming a trusted digital assistant truly owned by users, redefining the digital gateway to future personal life.
