Various blockchain watchers noticed suspicious transfers from a hot wallet known to belong to the CoinEx cryptocurrency exchange. CoinEx later confirmed a “security incident” involving “unauthorized transactions”. They wrote that the “precise amount of the loss is still being determined”, but tried to reassure customers that it was “just a very small portion of CoinEx’s total asset[s]”. Independent blockchain observers have estimated the losses at at least $30 million in various assets, including the ETH, Tron, and Polygon (MATIC) tokens.
CoinEx is based out of Hong Kong, and was recently forced to stop serving US customers as part of a settlement with the New York Attorney General which also required them to pay a $1.7 million fine.
