Ethereum underwent a chain reorganization, causing THORChain to trigger an emergency pause.

An Ethereum chain reorganization caused the cross-chain protocol THORChain to mistakenly issue a double refund to a user who deposited 10 ETH, triggering an emergency pause. This unexpectedly delayed the process of North Korean hackers laundering funds stolen from Binance. THORChain's status interface shows that transactions on 12 of its 13 listed chains are paused, while outbound signatures remain enabled on most chains. (Source: TokenPost, The Defiant)
