Nonetheless, Bonq reportedly carried out a Group Liquidation Characteristic the place 45 Troves with BEUR publicity had been liquidated as a result of incident. In line with CertiK, the assault additionally impacted Troves containing roughly 110 million Alliance Block tokens (ALBT). That stated, not one of the Alliance Block sensible contracts had been breached through the incident, and the challenge has stated it is going to airdrop new tokens to compensate affected holders.
Bonq protocol was uncovered to an oracle hack, the place exploiter elevated the ALBT value and minted massive quantities of BEUR. The BEUR was then swapped for different tokens on Uniswap. Then, the value was decreased to virtually zero, which triggered the liquidation of ALBT troves.
