Justin Sun Vows to Cover All Losses After Crypto Hack

Blockchain security company Cyver had flagged suspicious transfers amounting to $85 million earlier today. According to a message Cyver sent to CoinDesk, the attack was likely due to a leak of private keys. This would have allowed hackers to access the bridge between Heco Chain and Ethereum, enabling the transfer of tokens between the two.

Heco Chain was established by HTX, which has remained one of its maintainers. A spokesperson for HTX said that HTX and Heco Chain operate independently.

This incident comes after HTX suffered a smaller exploit in October, when hackers stole 500 ether worth around $8 million from the exchange. HTX covered all losses in the days after that hack.

While HTX has pledged to reimburse customers, major hacks can deal lasting damage to platforms through loss of confidence and strained finances. Heco Chain and HTX will need to identify and fix the security vulnerabilities to regain user trust. For now, the companies must focus on supporting affected customers as investigations into the hack continue.
