Binance, the world’s largest cryptocurrency exchange, has said it’s investigating reports of a potential $6.3bn security breach that analysts said could amount to the most significant incident relating to digital assets on record.

It wasn’t immediately clear the extent of the damage hackers might have been able to cause, and Binance did not explicitly confirmed that funds had been stolen. The company said its teams are “working around the clock” to resolve the issue.
