Catalyx, a Canadian cryptocurrency exchange, has recently faced a setback as it decided to halt withdrawals and suspend all trading activities due to a detected security breach. The exchange suspects that one of its employees might be involved in the breach, leading to the potential loss of some crypto assets held on behalf of its clients. Although the specific amount of the lost assets remains undisclosed, the incident prompted the temporary suspension of both cryptocurrency and fiat currency withdrawals and all trading activities on the platform.
