BlockSec: SushiSwap's KashiPairMediumRiskV1 contract has a logical loophole: On December 16, BlockSec stated that SushiSwap's KashiPairMediumRiskV1 contract suffered two attacks due to a logical loophole, resulting in a miscalculation of token prices and asset losses. The Sushi team then took action to protect some valuable but vulnerable pools from attack, and to provide a program to compensate users who lost funds due to the vulnerability.

BlockSec reminds that dozens of fund pools built on Ethereum and BNB Chain may be affected by this vulnerability. The temporary solution to this problem is to occasionally or periodically call the UpdateExchangeRate function to reduce or eliminate the deviation. [2022/12/16 21:49:06]

Blockchain startup BlockCrushr drops lawsuit accusing ConsenSys of stealing its IP: Canadian blockchain startup BlockCrushr has agreed to drop its intellectual property (IP) lawsuit against Ethereum-focused software engineering firm ConsenSys.

Earlier news, Canadian financial technology company BlockCrushr filed a lawsuit in New York, accusing blockchain technology company ConsenSys of stealing trade secrets. A day before BlockCrushr launched its product, ConsenSys launched an ETH-based recurring payments platform called Daisy Payments.
