I have just been following this channel just recently. To your point, we at Bastion Trading, feel it would be quite a privilege for us to present a proposal to the OHMies to market make on CEXes - and join in on a RFP bidding process. Of course, to be fair, Wintermute and GSR are highly experienced trading firms no doubt who can get the job done.
However, I have been thinking that our proposal would be more of a proof of work proposal, as opposed to receiving so much economics (a large notional of call options and a large notional of borrow for free) up front - in fact - a proposal that may complement the two current firms' ideas.
I want to note that a RFP selection process doesn't even have to result in simply one market maker chosen for the requested set of economics, just like a in a IPO process in tradfi - all the bookrunners and underwriters share a fee pool and in most cases there's several firms working on a deal. I would argue that for trading - as for an issuer - its better to have many market makers competing on bid/offer, volumes, and positioning.
As a brief introduction, Bastion Trading is a crypto trading firm, that has been trading crypto (trading arbitrage, market making, stat arbitrage) since 2017, and has traded billions in that time period. Currently, there's many other qualified trading firms in crypto with many different ideas and solutions (it can be overwhelming as well) - but well worth a look to look at the many choices.
Since the proposal is seemingly live, I'll leave it brief here, and if all of you would like to see another proposal or eventually this all goes to a RFP, we'd be happy to post it in an appropriate place (and/or time). Thanks for reading!
