USDX (by HT Digital Assets / Hex Trust)

USDX is a 1:1 USD-referencing stablecoin issued by HT Digital Assets, the tokenization ecosystem of licensed digital asset custodian Hex Trust. It is designed to be fully backed by US Treasuries and cash equivalents held with regulated custodians, with reserves subject to regular attestation reports. USDX is available on BitMart, Curve, and SparkDEX, and can earn yield through curated investment vaults on Clearpool.

USDX itself does not pay yield. The issuer (HTMI Limited) does not pass along any interest earned from the reserves backing USDX to holders.

Instead, yield is created separately when you take your USDX and put it into special Investment Vaults on Clearpool, which are run by professional asset managers. There are three types of vaults:

• T-Pool — yield comes from short-term U.S. Treasury Bills (1–3 months), meaning low-risk returns based on real-world government debt.
• X-Pool — yield comes from "delta-neutral" arbitrage (a strategy that tries to lock in small price differences between exchanges while avoiding market-movement risk).
• Pay-Fi (coming soon) — returns from lending cash to leading payment fintech companies.

When you deposit USDX into the Clearpool T-Pool on the Flare network, you receive cUSDX (a token that represents your deposit 1:1). You then automatically start earning yield, plus bonus FLR token rewards distributed by the Flare network.

There are no lock-up periods — you can deposit or withdraw anytime. You can also claim your rewards (both USDX and FLR) continuously without touching your original deposit.

The cUSDX token can also be used as collateral inside Flare Labs' FAsset system, which lets non-smart-contract assets like Bitcoin (BTC) and Dogecoin (DOGE) work in DeFi.

USDX is issued by HT Digital Assets, the tokenization ecosystem of Hex Trust. Investor information pertains to the parent company Hex Trust rather than a separate USDX funding round.
