The cryptocurrency exchange Binance halted trading due to an issue with the API endpoint. CEO Changpeng Zhao said this.
Our system detected a potential matching error, and the matching was automatically suspended. We are looking into the issue. May take 30–60 min by initial estimate (may change). Will keep you updated. https://t.co/ryxkV5oRGW

According to Zhao, the system detected a potential order-matching error, after which the matching engine was automatically halted.
“We are studying the problem. Preliminary estimates suggest it may take 30–60 minutes (timing may change),” wrote the exchange’s CEO.
He noted that deposits, withdrawals and transfers had been paused. The futures market’s order-matching engine is operating normally.
Spot matching engine is in maintenance mode. All deposit/withdraw/transfer features are also paused.

Binance representatives assured users that their funds were safe. Before resuming trading, they would have half an hour to cancel orders, make deposits, withdraw funds or transfer assets.
Zhao later said that specialists had relaunched the order-matching engine.
“We are now checking other systems. Engineers tell me that this will take at least 30 minutes, so perhaps another 60 minutes,” the exchange’s CEO said.
Update: Changpeng Zhao said Binance was returning to normal operations. Trading would resume shortly.
