Yes, it is a fork of Monero (which I also own, of course), so it has the same gold-standard privacy features as XMR. Basically it works like this:

It has a main coin, XHV, which can be used on its own just like Monero. What the Haven guys added was an exchange that is completely built-in to the protocol, where you can convert right in the wallet, so your coins always stay in your control, that was what I really loved about this project, I hate putting my coins at risk every time I want to trade! Your keys, your coins! It uses the "mint and burn" system, so if you have $100 worth of XHV, you can convert it to their 100% private stablecoin called xUSD, and it burns the XHV and mints 100 xUSD (small fee of 0.5%: this fee is split between miners, some goes to fund development, and the rest is burned). The best part is that there is 0% slippage, and there is essentially unlimited liquidity, since the asset you are swapping to is being minted at a set rate, plus it doesnt create any inflation this way.

Then, once you have xUSD, you can convert it back to XHV any time, or you can convert it to other private xAssets such as xBTC, xEUR, xCHF, xAU/xAG (gold/silver), and a few more. So its like a savings account that is completely private, that you can hold in the currency of your choice. A few small exchanges have a small amount of trading pairs for xAssets too, but it is pretty early, so its still very low volume. You can of course send and receive xAssets just like Monero or haven coins too. And everything being in one place right in the wallet is really convenient.

Anyway, I hope that helps! The project is still rather early, they just got everything working without issues a few months ago, but I am slowly seeing people mention it more, and am very excited about it. The haven and Monero community also seem to be very friendly with one another, and in fact the Haven devs even helped with some Monero development, they recently reported a critical Monero bug a few weeks ago that was a big help, someone mentioned it in the Monero reddit page.
