Boy X Highspeed (BXH), a decentralised cross-chain exchange, was hacked in October in a hack that drained $139 million of funds. This was probably the result of a leaked administrator key, and possibly an inside job. With the private key, the attacker was able to digitally sign a transaction transferring $139 million in tokens from BXH’s account on BSC to their own account.

 

BXH’s CEO stated that an investigation was underway to identify the hacker. If the hacker is not found, BXH has said that it will devise a user repayment plan and is offering $1 million to teams able to help retrieve the funds.
