ARP Digital says it's the "first and only central bank-licensed OTC service provider specialized in digital-asset structured products." Digital asset services firm ARP Digital, which boasts a former Goldman Sachs partner as one of its co-founders, received a license from the Central Bank of Bahrain to operate in the Middle Eastern country, providing services including crypto trading, custody, and portfolio management services to customers. The firm got the category-3 license over the weekend and is the only over-the-counter (OTC) service provider focused on structured products that Bahrain's Central Bank regulates, ARP Digital said.
