What is the real risk involved in "Early Settlement" (BCHBull)?

"Any contracts that have this enabled will be at risk if both the liquidity provider and your browser are compromised."

According to this sentence, as long as my browser is not compromised there would be no problem, even if the liquidity provider has been compromised, right?

"You can early settle any contracts that have this enabled by paying a market premium."

Does this "Market Premium" correspond to the one I had when I started the contract?

Thanks in advance, I'm trying to understand how this system works before starting to use it.
