Switzerland’s SIX Digital Exchange (SDX), the digital asset exchange, and FQX, a SIX Fintech Ventures portfolio company, have agreed to collaborate to enable the use of FQX’s blockchain-based short-term debt instruments, eNotes, on SDX. An eNote is an unconditional promise to pay a specific sum to another party at a specific future date and can be modularly structured to fit any financing purpose. The eNote is based on blockchain technology and can be easily transferred to any third party.
