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
AI infrastructure operators face a financing gap for expensive GPU hardware while DeFi capital lacks access to high-yield real-world cash flows. Existing yield-bearing stablecoins are exposed to crypto-market funding rates rather than real economic activity.
The Solution
USD.AI originates non-recourse loans secured by GPU hardware and asset-level cash flows, then tokenizes the credit exposure as sUSDai. Depositors get yield from real AI infrastructure economics; operators get non-dilutive financing.
Why it Matters
First-mover in 'InfraFi' (compute-backed credit). Stablecoin layer (USDai) is fully isolated from credit risk and backed 1:1 by PYUSD; risk is concentrated in the staked sUSDai layer.

The CLARITY Act: How the Missing Half of US Crypto Law Reshapes Stablecoins, RWAs, and DeFi
GENIUS legitimized the dollar on-chain. The CLARITY Act is the second half — it decides who regulates everything the dollar trades against, hands stablecoin yield to venues like Pendle, and turns RWAs into a global gateway that finally lets non-US users reach markets they were locked out of. Here's how to trade it.
USD.AI: Turning the GPU Financing Gap Into On-Chain Yield
AI data centers need hundreds of billions in capital that banks are too slow to lend, while GPUs lose a fifth of their value every year. USD.AI closes that gap with GPU-backed loans and pays the interest to depositors. Here's how the protocol works, where the risk really sits, and the four ways to participate — ranked.
