SDAT Institutional Investor Alliance (SDAT Alliance) has been founded and the SDAT decentralized exchange has been created. There are two reasons for this. On the one hand, the enterprises can directly issue their own tokens in the innovative and unique DIYO (Do-It-Yourself-Offering) model as expected, and thus they can widen their trading channels by sharing trading depths in SDChain-supported decentralized exchanges such as the SDAT decentralized exchange and exchanges belonging to other SDAT Alliance members. On the other hand, the SDAT Alliance members who are very experienced in the investment industry, can utilize SDAT membership tokens, to access the rights and the interests of members at private fund-raising roadshows to perform due diligence on projects, and help support high-quality capital investment projects. Consequently, investors receive fair and transparent treatment in the private placement process.In other words, the emergence of the SDAT decentralized exchange is expected to cleverly beat the blind spots in the current market mechanism and truly open the way for a tokenomics-based investment industry.
