Proplex is a decentralized RWA platform on U2U Network enabling secure, compliant fractional ownership of real-world assets with sub-second finality and low fees.
ZYURA makes flight delay insurance simple and instant using Arbitrum. Travelers pay a small premium, and if their flight is delayed, payouts are triggered automatically through smart contracts. No paperwork, no claims, and no waiting, just fast, reliable coverage. We make travel insurance transparent, affordable, and accessible to everyone.
ArbSky is building the intelligence layer for decentralized finance on Arbitrum, combining verifiable on-chain computation (via Stylus) with user-sovereign data (via Skynet). Unlike existing AI-driven DeFi tools that rely on opaque off-chain systems, our platform enables trustless AI execution, portable strategy ownership, and transparent risk management. This creates a user-owned, composable, and monetizable intelligence layer—positioned to serve DeFi power users, DAOs, and eventually institutions.
