The leading Korean cryptocurrency trading platform Upbit has issued an official announcement stating that it will suspend the deposit and withdrawal services for ADA (the mainnet token of Cardano) starting at 14:00 KST on September 1 due to the need for a Cardano network upgrade. This measure aims to ensure that platform users can safely conduct trading activities during the upgrade period. Cardano network upgrades typically involve improvements and optimizations of blockchain technology to enhance network performance, security, or introduce new features. For users who trade ADA through the Upbit platform, this means they will not be able to perform any fund transfer operations related to ADA during this period. Upbit advises users to plan their trading strategies in advance to avoid potential inconveniences. Once the upgrade is complete, the relevant services will resume.
