Score history
This rating is re-checked every month. A point is recorded for every check, so a flat line means we looked and nothing moved. Hover anywhere on the chart to see what moved that month, and by how much.
The Problem
Institutional-grade delta-neutral yield strategies are typically gated by capital minimums and accreditation, and Solana lacks a major native synthetic dollar with on-chain proof-of-reserve.
The Solution
USX is a Solana-native overcollateralized synthetic dollar with permissionless retail access, real-time Chainlink Proof of Reserve, and yield-bearing eUSX exposure to a multi-strategy delta-neutral book.
Why it Matters
First major Solana-native synthetic dollar at scale (~$378M TVL, 12th-largest on Solana). RWA-diversified collateral, Squads multisig + 24h timelock upgrade authority, and a Halborn-audited program stack with on-chain PoR.
