# Sky Ecosystem > Sky Ecosystem is a global savings and capital allocation network managing billions in diversified assets. It powers the Sky Savings Rate — engineered for the best risk-adjusted yield at scale — through a decentralized protocol and an independent network of capital allocators called Sky Agents. Sky Ecosystem evolved from MakerDAO, the pioneer of decentralized stablecoins and onchain governance since 2014. The protocol operates on Ethereum with open-source smart contracts, institutional-grade security, and over eight years of continuous development. Sky Protocol is the first DeFi architecture to receive a formal credit rating from S&P Global. The ecosystem is governed entirely onchain by SKY token holders. Core assets include USDS (a fully backed stablecoin and the upgrade of DAI) and sUSDS (the yield-generating savings stablecoin representing the Sky Savings Rate). The website is managed by Sky Frontier Foundation (SFF), an independent entity without authority over Sky Protocol, its smart contracts, or governance decisions. Typical audiences: DeFi users seeking yield on stablecoins, institutional capital allocators evaluating onchain deployment strategies, developers integrating with Sky Protocol smart contracts, and governance participants staking SKY tokens. ## Products - [USDS](https://www.skyeco.com/products#usds): The foundational stablecoin of Sky Ecosystem — fully backed, soft-pegged to USD, and the base unit of capital for borrowing and liquidity across the Sky Agent Network.
