oh great!
thanks for the link 
makes perfect sense for using Bridgeless to "external" chains; but ZEL is Zano's own sidechain β so the question remains, "is ZEL itself privacy-preserving or just standard (public) EVM?" 
if it's the latter, fUSD in an AMM pool there would have visible amounts and balances β and perhaps be considered too big a (privacy) shift from the L1
not sure what the plan is, but here are 2 possibilities:
(1) Aztec is doing zk-powered private smart contracts with their Noir language β probably the closest thing to real private EVM execution β and definitely the one I'd favor 
(2) while Railgun takes a different approach β utilizing shielded pools on top of existing EVM chains rather than privacy at the execution layer
imo, both are pretty interesting β but also feel very different in terms of what they'd mean for (and how they'd integrate into) ZEL
any sense of which direction the team is leaning?
or perhaps it's still early
