# About USDhl

#### What is USDhl?

USDhl is a fiat-backed stablecoin custom-built for the Hyperliquid ecosystem. It serves as a building block for HIP-3, FX, payments, and more.

Furthermore, unlike legacy fiat-backed stables, yield from USDhl is distributed back to users. 

**Additional Info:**

* USDhl is powered by [M0](https://www.m0.org/)'s stablecoin infrastructure - it is backed 1:1 by M, a wholesale dollar collateralized by short-term treasuries.
* USDhl is a public good built by [Felix](https://usefelix.xyz).
