Approximately $125 million worth of multi-chain assets has been observed flowing out of the cross-chain protocol Multichain into multiple wallets. As a response, the Multichain team has temporarily halted the protocol, without providing a specific timeline for recovery.
Some analysts suggest that the situation may not be a result of a hacker attack. They point out that the asset transfer occurred gradually, with a small test transfer of 2 USDC before the larger outflow. Each asset was transferred to an independent wallet, and no further actions such as swapping or mixing took place. The receiving wallets remain completely clean.
Considering the technical characteristics of Multichain, it is possible that the transferor gained control of private key fragments exceeding the threshold through some means. The investigation into this potential exploit is ongoing.
