No. Zerocoin in it's current state is basically broken technology with most big projects moving away from it completely (For example: Zcoin and Veil are developing brand new protocols to replace Zerocoin).

In regards of Solaris though, we don't see a privacy protocol being as a point of attraction. No one used Zerocoin on XLR since it was activated over a year ago.

Stratis are working on a trustless coin mixer which we may integrate in the future as well, but it's not a priority.
