About InterOpera

InterOpera is a Singapore-based fintech that develops and implements blockchain technology to provide the infrastructure needed for digitalization of capital markets products, by focusing on inter-chain bridging and interoperability across blockchain platforms. Shareable Assets Pte. Ltd. is its wholly-owned subsidiary operating under a capital markets services license from the MAS. 

To date, we have raised USD 9 million led by Korea Investment Partners. Among other investors, we are backed by Vertex Ventures and Kakao Investments. 

What we are building: Ultimate Bridge of Capital Markets

InterOpera is building an interoperable layer 1 network using proprietary RDOS (Regulated Defi Operating System) to directly interconnect investors. RDOS is a PaaS (Platform-as-a-Service) product of the interoperable blockchain infrastructure for capital markets participants (Governments, Financial Institutions, and Investors). RDOS acts as a gateway to unlock and enable blockchain-based efficiency within the current regulatory and securitization framework via smart contracts. As the ultimate middle-layer product for market participants, RDOS improves efficiency for participants of the existing system without sacrificing investor protections. RDOS contributes to financial inclusion by: 1) enhancing market accessibility, 2) enabling legal ownership of tokenized assets, and 3) reducing transaction costs in the long run.
