Binance has vowed to raise the quality of its security in the aftermath of a hack that saw thieves make off with over $40 million in Bitcoin from the exchange.

The company — which is widely believed to operate the world’s largest crypto exchange based on trading volumes — said today that it will “significantly revamp” its security measures, procedures and practices in response. In particular, CEO Changpeng Zhao wrote in a blog post that Binance will make “significant changes to the API, 2FA, and withdrawal validation areas, which was an area exploited by hackers during this incident.”
