26th September 2025 – CUDIS, a healthtech startup known for its AI-powered wearable ring, has announced its expansion to the Sui blockchain. The move was revealed during Korea Blockchain Week and marks the company’s entry into Asia’s growing digital health and wellness market.
The integration allows users to store and control their biometric data on-chain using Sui’s Layer 1 infrastructure. CUDIS will use Walrus for decentralized storage and Seal for privacy-preserving encryption. The goal is to build a decentralized health economy that offers users ownership, utility, and monetization of their personal health data.
Originally launched on Solana, CUDIS has since expanded to Worldcoin and now Sui. The startup raised $5 million in seed funding in 2024, led by Draper Associates. To date, it has sold over 25,000 rings in more than 100 countries and generated more than $6 million in revenue.
As part of the partnership, CUDIS is launching a Sui-branded version of its smart ring. The limited-edition product is priced at 113 SUI (approximately $350) and is capped at 1,500 units. Pre-orders opened immediately after the announcement, with a global shipping date set for December 2025.
The ring tracks over 30 physical activities and key vitals such as heart rate variability, blood oxygen, temperature, and sleep. Users can own their health data as NFTs, monetize it through a marketplace, and earn $CUDIS tokens for healthy behavior.
Sui Ring holders will receive a six-month benefit period, including point multipliers, access to exclusive challenges, and eligibility for ecosystem airdrops. Airdrop rewards include up to 13,000 tokens for top-ranking participants. CUDIS also plans to offer offline wellness events and early access to future longevity services.
CUDIS cited Sui’s performance, privacy features, and modular infrastructure as key reasons for the integration. The expansion uses Sui Stack, which includes support for execution, consensus, developer tools, and user-facing features. The data architecture supports secure storage and on-chain indexing of health data.
The integration aligns with Sui’s broader Asia strategy. The company recently partnered with T’Order, a Korean table-ordering app that uses Sui for stablecoin-based payments.
CUDIS is positioning itself as a hybrid of AI coaching, gamified health tracking, and user-owned data systems. It aims to build a multi-chain protocol for longevity and wellness that targets over 600 million users.
The company’s roadmap for the remainder of 2025 includes an upgrade to its AI coaching system, a new staking portal, and the launch of a health-focused dApp ecosystem. CUDIS also plans to expand into Europe in November through partnerships with Superteam UK and Germany.
Token holders and ring users will participate in future airdrops, product launches, and governance. The $CUDIS token currently has a fully diluted valuation of around $80 million.
The integration with Sui is intended to improve data interoperability and scalability, two long-standing challenges in digital health infrastructure. CUDIS aims to offer users greater control over their biometric data while supporting research, AI development, and community-driven health initiatives.
