Financial Loss $107.0M (107,000,000 USD)

Incident Details

Only five days after $130 million was emptied from the Multichain blockchain bridge, another $107 million in a wide range of assets has been taken. After the first theft, Multichain urged users to stop using the project and revoke contract approvals, but a large quantity of assets remained on the service.People are becoming increasingly suspicious that the Multichain thefts may be an inside job, not least because Multichain’s CEO suddenly disappeared in late May and hasn’t been located since.

Total loss estimated at $107,000,000.
