**USDh:** The first **Bitcoin-backed synthetic dollar** that yields up to **15%**.

Until now, the Bitcoin ecosystem lacked an essential building block  -  a dollar asset that is fully backed by Bitcoin, yield-bearing, and native to Bitcoin L1 and L2s.

Hermetica’s USDh accomplishes all the above and finally brings the ideal synthetic dollar to the Bitcoin ecosystem. USDh lets you hold dollars and earn yield without leaving Bitcoin. No banks, no fiat — just Bitcoin.

#### Get Started

1\). Buy USDh - Available on Stacks through [Velar](https://app.velar.com/swap?fromtoken=USDh) and [Bitflow](https://app.bitflow.finance/trade?x=USDh)<br />2). Stake for up to 15% APY - Stake USDh on [hermetica.fi](https://app.hermetica.fi/stake) and start earning<br />3) Use in Bitcoin DeFi - Trade, lend, and earn additional yield
