  We consider the problem of being a cross-chain wealth management platform
with deposits, redemptions and investment assets across multiple networks. We
discuss the need for blockchain bridges to facilitates fund flows across
platforms. We point out several issues with existing bridges. We develop an
algorithm - tailored to overcome current constraints - that dynamically changes
the utilization of bridge capacities and hence the amounts to be transferred
across networks. We illustrate several scenarios using numerical simulations.
