Sky

Sky is the successor to MakerDAO, the pioneering DeFi protocol that first introduced decentralized stablecoins on Ethereum. It governs and issues USDS, a crypto-backed stablecoin designed to maintain parity with the U.S. dollar without depending on banks or centralized custodians. Sky operates entirely through smart contracts, ensuring that decisions and risk management are handled transparently onchain. Guided by a global community of token holders, it emphasizes decentralization, censorship resistance, and the long-term resilience of open financial systems.

Self Protocol

Self Protocol is an identity verification system that leverages zero-knowledge proofs to enable Sybil-resistant token distributions and user authentication without compromising personal data. By validating user attributes such as age or location through passport verification, Self Protocol ensures that decentralized applications can authenticate real users while maintaining privacy.

Giveth

Giveth is an open, non‑hierarchical global initiative that empowers social, environmental, and humanistic impact projects using modern blockchain technologies. Built on Ethereum, the platform enables zero‑fee donations and ensures full transparency so donors and communities can see exactly where every contribution goes. Through the GIVeconomy, donors receive GIV tokens via the GIVbacks program and can participate in governance and project visibility via mechanisms like GIVpower and Quadratic Funding .
