AscendEX loses $80M following ERC-20, BSC, Polygon hot wallet compromise

Crypto trading platform AscendEX suffered a loss of $77.7 million in a hot wallet compromise that allowed hackers to access and transfer tokens hosted over the Ethereum (ETH), Binance Smart Chain (BSC) and Polygon (MATIC) blockchains.

Soon after realization, AscendEX proactively warned its users about the stolen funds, confirming that the hackers were not able to access the company’s cold wallet reserves.

According to PeckShield, a blockchain security and data analytics company, around $60 million worth of tokens were transferred over the Ethereum blockchain. Tokens stolen from the Binance Smart Chain and Polygon are worth $9.2 million and $8.5 million respectively, as evidenced by EtherScan data.

Some of the popular tokens stolen in this hack include USD Coin (USDC), Tether (USDT), and Shiba Inu (SHIB). However, AscendEX is yet to officially confirm the exact worth of the tokens taken away by the hackers. 

The company also announced to help the affected users by covering up their losses due to this attack.
