Fund manager trades being routed through 3rd-party DEXs are subject to protocol-specific trading fees. However, it is conceivable that significant volumes of fund managers’ trades will have another fund manager as the counterparty. This presents a potential fee-saving opportunity for fund managers if the trade can take place on the SolStreet protocol (the potential lower bound for fees is zero when summing the maker and taker fees). This could be achieved by having fund managers' limit orders simultaneously sit on a SolStreet order book AND a Serum order book. This should also help attract market makers to the protocol.
