Digital Asset Markets, Intertrade, and AndGo said they have completed a proof of concept integrating AndGoWallet with Fireblocks, a digital asset custody and transfer platform used by financial institutions. In a May 13 announcement, the companies said the test verified the technical feasibility of a custody setup that blends in-house key management with international standards. The result points to a model aimed at institutional digital asset storage, where firms seek tighter control over private keys while still using established custody technology.
