Hubble is a fee-sharing decentralized finance (DeFi) protocol built on Solana that will offer multiple DeFi services as the protocol and DeFi continue to mature and expand. Hubble begins its DeFi Phase 1 by offering zero-interest loans that can be collateralized by multiple assets including SOL, BTC, ETH, RAY, SRM, and FTT with other options for collateral deposits added as they are approved in the future (BNB, DOT, AVAX, LUNA etc).
Borrowers can increase the capital efficiency of their deposits by withdrawing Hubble's stablecoin, USDH, against their collateral so long as they maintain a collateral ratio above 110%. These loans are further guaranteed through a stability pool of USDH deposits made by guarantors who share the difference in liquidated collateral assets when a loan’s ratio collateral ratio falls below 110% and those assets are used to repay the loan.
