On May 12, the L1 blockchain TAC team experienced a security incident, which has now been largely resolved. According to Foresight News, the attackers have voluntarily returned approximately 90% of the funds dispersed across Ethereum, TON, TAC, BNB Chain, and Zcash, retaining 10% as a bounty. TAC has stated that the imbalance in cross-chain layer funds will be fully rectified, with a detailed update and comprehensive post-incident analysis report to be released soon.
Previously, on May 14, TAC confirmed that the cross-chain layer security incident resulted in the transfer of approximately $2.8 million in assets (USDT, BLUM, and tsTON) to specific addresses. TAC indicated that if the attackers returned the funds, it would be considered a white-hat rescue, with a bounty of about 10% offered.
