Solstice (@solsticefi) is building a Solana-native stablecoin system. $USX is its stablecoin. It is over-collateralized and backed on-chain. If you deposit $USX into the YieldVault, you receive eUSX which a yield-bearing version of the stablecoin. Instead of trying to guess whether prices will go up or down, Solstice helps you earn yield using strategies designed to work in either direction.
