Overdrafts?

What is Monzo’s plan for overdraft in the US? Overdrafts in the US are generally a bad thing resulting in a $35-$45 fee. Is Monzo attempting to take more line of credit like approach, as in the UK?

The overdraft fee is a large reason so many Americans are unbanked, or using high-fee prepaid cards.

I wonder if they can even offer overdraft without a full banking license of their own (as in, I don’t think it’d be happening anytime soon). But yes, I’d definitely be interested in an overdraft credit line that only charged interest if they offered it.
