Hubble Protocol is a financial platform building sustainable Decentralized Finance services on Solana. Hubble’s core service centers around a low-interest, stablecoin borrowing mechanism. Hubble’s US Dollar-pegged stablecoin, USDH, can be borrowed against a variety of assets, including ETH, BTC, and SOL. While collateralized, these assets earn continuous yields with Hubble’s Yield-Mechanism, through which Hubble is laying the foundation to a comprehensive Yield Protocol across the Solana blockchain. Hubble’s vision is to collaborate with innovators on Solana and beyond to promote the democratization of finance, and to educate financial users on the rapidly evolving world of DeFi.
