The company's chief executive said that $200 million in cryptocurrencies had been stolen from the BitMart exchange's wallet.
The CEO of BitMart said on Monday that they discovered that the cryptocurrencies were withdrawn using a stolen private key.
"We have identified a large-scale security breach related to one of our ether hot wallet and one of our bscc hot wallet," Xia said.
The company said on Sunday that it had taken $100 million from the ethereum network and $96 million from the binance smart chain. The assets affected included meme coins.
The money was stolen using a simple technique called transfer-out, swap, and wash.
The hackers may have swapped the stolen token for ether after getting the funds out of BitMart. The money is difficult to trace if the hacker deposited it into a privacy protocol.
The centralized global exchange that is based in the Cayman Islands and BitMart suspended withdrawals from itscryptocurrencies were the two places that Xia said $150 million was stolen from.
The company hopes to resume the deposit and withdrawal functions on December 7. BitMart will use its own funding to compensate affected users and they are talking to project teams about the most reasonable solutions such as token swaps.
There are other exchanges that have been hacked using a private key. Boy X Highspeed, a cross-chain exchange, had $139 million taken in early November. The company's CEO Neo Wang said that it was probably an inside job.
Alex Mashinsky, CEO of the Celsius Network, said last week that the platform had lost $120 million from a hack.
More than $600 million worth of cryptocurrencies was stolen from the poly network in August, but nearly half of the money was returned.
