Solstice is a Solana-native synthetic dollar protocol issuing USX (overcollateralized stablecoin) and eUSX (yield-bearing receipt), backed by delta-neutral strategies and tokenized treasuries.
How a reserve-backed deposit becomes USX, then a yield-bearing eUSX position
Solstice mints USX 1:1 against deposited stablecoins. The collateral is held in Solana program vaults and at off-exchange custodians Copper and Ceffu, with reserves attested on-chain in real time by Chainlink Proof of Reserve. Drag the deposit to mint more USX and watch the backing gauge.
KYC participants mint at no spread; retail can swap USX on Raydium, Orca or Jupiter.
Reserves exceed issued USX (overcollateralized). The white line marks 100% backing — the green fill sits above it because the diversified collateral book holds a buffer beyond the 1:1 peg.
