Crypto derivatives platform quality — how do you evaluate it before trading real size?

Question for the community for those who trade both traditional futures (ES, NQ, CL) and crypto derivatives (BTC/ETH perps, futures):

How do you evaluate the infrastructure quality of a crypto derivatives platform before committing serious capital?

With CME futures, infrastructure quality is guaranteed by regulation Globex matching engine, SPAN margin, standardized clearing. But crypto derivatives platforms are all over the map.

I’ve been researching what separates a well-engineered crypto derivatives exchange development from a poorly-built one specifically looking at matching engine throughput, mark-price methodology, liquidation engine design, and insurance fund depth. The differences are significant and directly affect execution quality during high-volatility periods.

A few things I look for:

Mark price vs last traded price — does the platform use a composite spot feed to calculate margin and liquidation prices, or last traded price (which can be gamed)?
Partial vs full liquidation — does the engine reduce position size gradually before full close-out, or dump everything at once?
Insurance fund size relative to open interest — is it meaningful or cosmetic?
Funding rate transparency is the formula published and verifiable?

Curious what criteria others here use when choosing a crypto derivatives venue. Or do most traders here stick entirely to CME-regulated products and avoid crypto platform risk altogether?

Trading futures involves substantial risk of loss. Educational discussion only.
