Gateway Layer

• Web3 Payment Gateway: Connects wearable devices with blockchain payment systems, supporting offline QR code payments and near-field (NFC) payments via smartwatches or bands. Compatible with major stablecoins and ASTRA tokens, automatically completing on-chain transaction signing and submission for a seamless “pay-with-a-lifted-hand” experience. Integrates with traditional payment institutions, supporting exchanges between Web3 assets and fiat.

• Web3 Health Data Gateway: Serves as a hub for user health data flow, connecting wearable devices with ecosystem applications via APIs. Uses Zero-Knowledge Proof (ZKP) technology to encrypt data for “usable but not visible” access. Employs NFT technology to confirm data ownership, allowing users to authorize medical or insurance institutions and earn revenue.

• Web3 Insurance Gateway: Connects insurance providers with users’ on-chain health data, enabling dynamic adjustment of insurance premiums based on historical health data and activity habits. Supports personalized health and sports insurance products. Users can complete policy purchases and claims submission via wearable devices, with smart contracts automatically executing claims to enhance efficiency and transparency.
