Perps traders, can I ask you something?

I'm helping to build a perps exchange, and one of the features everyone is set on is multi-collateral margin (you'll be able to deposit tokens beyond the regular USDT). I think this is a cool feature, but I think there may be different opinions about which assets, and why people are using them.

This is going to be on ETH L1, for reference, so anything we add needs liquidity on ETH L1. Here's what we have:

1. Regular stable (that's a given, we're using USDT)
2. Yield bearing stable (sUSDe is what we're using, but stataUSDC from Aave is possible)
3. ETH LST (wstETH from Lido)
4. Wrapped BTC (we're using cbBTC)

Here's what I want to explore:

A. Deeply liquid ERC-20 tokens like LINK, UNI
B. Regular ETH (selling ETH for wstETH is a taxable event, and yields aren't that high to make the tax worth it for some)
C. RWAs (PAXG, a tokenized gold ounce, is probably the only liquid one, but I expect just announcing we're adding RWAs would be big)

So my question is this:

Do you think the direction we're already headed (points 1-4) is compelling at all? Is my personal list (A-C) more interesting? Is this not interesting at all, and maybe you just want to trade using USDC like everywhere else? Do you understand what's happening here and why?

My 2 goals here are to make sure we can offer something maximally useful, and also something easy to explain. My big fear with the assets we have already is they require a LOT of explanation, which doesn't mean supporting them is bad, but makes me wonder how we're really going to present this cleanly in a way that makes people go, "wow, I can use that".

Thanks in advance for any feedback!

And yes, I left the name of the project out intentionally. My goal is to get feedback about the idea, not spam you. 🙂
