# USDX

Understand USDX, the mortgage-backed stablecoin built for global settlement and institutional liquidity.

## Real estate stability. Digital asset flexibility.

USDX is a USD-pegged stablecoin backed by a reserve portfolio of U.S. residential mortgages, agency mortgage-backed securities, and liquid reserves. Stable brings the assets, cash flows, and risk controls of mortgage markets onchain for transparent, programmable settlement.

## Staked USDX

[Staked USDX](/protocol/usdx/staking-usdx.md), or mUSDX, is a non-rebasing exchange-rate wrapper. Yield retained by the staking vault increases the amount of USDX redeemable per mUSDX rather than changing the holder's token balance.
