Gravita is a decentralized protocol that allows users to borrow GRAI, a decentralized currency, interest-free. Users can deposit assets as collateral into a Vessel and borrow GRAI with a one-time fee. The protocol supports borrowing against liquid staking tokens, enabling users to earn staking rewards on their collateral. Additionally, its Constellation feature, powered by NodeSet, aims to enhance decentralization and capital efficiency within the Ethereum staking ecosystem through products like xrETH and xRPL.
