    About XREX:

    XREX helps blockchain-focused organizations save time and money with product development, production maintenance, security, scalability, and compliance efforts.

    XREX Crypto Services (XCS) is a compliant, secure, scalable stack of PaaS and SaaS offerings for organizations that build and run crypto markets (spots, futures, options), market-making, banking, custodial services, wallets, clearance and settlement proxies, payment gateways, value transmission services, and/or decentralized apps.

    XCS stacks are offered entirely through cloud-based APIs and billed by usage. After registration, developers can immediately initiate module instances and use APIs; there are no face-to-face meetings, contract negotiations, setup fees, or monthly minimums.

    XCS allows organizations to focus on building core business functions--not waste time and money in developing, maintaining, scaling, and securing the underlying stacks.

    Many XCS services are implemented using XBLOCK, a blockchain designed for high volume, low latency clearance and settlement across financial institutions.

    XREX also operates a standalone market -- the XREX Exchange -- which provides professional access to spot, futures and options trading.

    * Taiwan Government National Development Fund
    * CDIB Capital Group (TWSE: 2883)
    * E.Sun Financial Holding (TWSE:2884)
