Dreamcash, the non-custodial trading platform backed by Tether, will close its CASH perpetual contract markets, citing the integration of USDC on its platform. The closure will occur between June 30 and July 2, with positions settled at external oracle prices and funding rates set to zero during this period. The move aims to address user experience disadvantages in USDT markets. Despite the closure, Dreamcash assures users that account balances and rewards remain unaffected due to its non-custodial architecture. The platform will continue to support other trading activities and focus on enhancing its crypto trading mobile application.
