Open Exchange (OPNX) will cease operations on February 14. The trading activity halt will begin on February 7 and users will be able to continue withdrawing funds until the final closing date. A new exchange called OX.Fun has emerged to replace OPNX. OX.Fun uses OPNX's native token, Open Exchange Token (OX), as collateral for the derivative transaction. The identity of the individuals or entities behind OX.Fun and their connection to OPNX remain unclear.
