The BNB token from cryptocurrency exchange Binance, the largest crypto exchange in the world, was stolen by hackers for about $570 million.
After the attack, Binance, handling 1.4 million transactions per second and moving $2bn worth of crypto assets per day, had to suspend its blockchain network temporarily.
The value of BNB sank more than 4 percent to $281.06 a coin on Saturday morning.
It was at $293.1 at noon on Friday when the news broke. BNB Chain suspended its blockchain for several hours before resuming at around 0630 GMT.
Binance losses kept below $100m
Company officials said that they minimised the losses to under $100 million, with CEO Changpeng Zhao tweeting: “An exploit on a cross-chain bridge, BSC Token Hub, resulted in extra BNB. We have asked all validators to temporarily suspend BSC. The issue is contained now.
