FxDEX liquidity

Watched the FxDEX interview with Ryan Matta with great interest.
One of the challenges mentioned, concerning the DEX, is liquidity.
For example, Gold/BTC or Tesla/Eth pairs.

Out of curiosity, what is the plan to build up this liquidity?
Can there be given some insight about that by team?

F.e. will liquidity has to come from community, or will certain companies come in to give liquidity?
Can anyone with certain stocks, let’s say Tesla, deposit them to trade for BTC for example?
Wonder how that works and what the filosophy behind it is?
