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.
Cpay is a Web3-powered payment ecosystem that bridges the gap between digital assets and real-world transactions. It combines decentralized payment protocols with physical payment infrastructure to make crypto payments as seamless as swiping a card or scanning a QR code.
ClearDeal is a blockchain-powered freelance platform that connects clients and freelancers with secure smart contracts, transparent payments, and low transaction fees on Arbitrum.
🚀 Koan - No-Code DeFi Platform Koan is a powerful no-code platform that enables users to design complex DeFi workflows and deploy decentralized applications through an intuitive node-based visual interface.

NEXA is a decentralized financing platform on the Arbitrum ecosystem that uses a tokenized Revenue-Based Financing (RBF) model. It connects Web3 investors, who collectively hold over $4 trillion in crypto capital, with boring businesses that have predictable revenue streams, such as laundromats, ATM machines, and vending machines. The platform's core focus is on transforming these everyday operations into Real-World Assets (RWAs), creating a new and transparent asset class. This ensures transparency and automation through smart contracts that track and distribute revenue shares.
Maxxit is a trustless, non-custodial agentic DeFi platform on Arbitrum that transforms Crypto Twitter insights into transparent, PnL-backed trading agents — powering a new agentic economy.
