AI overview

THORChain halted cross-chain swaps on multiple blockchains following an Ethereum block reorganization that exposed a refund bug, resulting in the erroneous return of 10 ETH to senders. Nodes are evaluating chains to re-enable them as they are deemed safe. The pause follows reports that the disruption may affect actors linked to the Binance hack, though the primary cause is the technical bug rather than a targeted attack.

    Report first recorded Nov 2, 10:00

    THORChain paused cross-chain swaps on Saturday following an Ethereum block reorganization that exposed a refund bug. The bug allowed the protocol to refund 10 ETH that had already been deposited, inadvertently triggering an automatic pause. The disruption also slowed the movement of funds stolen in the $6.3 billion Binance hack, according to Chainalysis, which said the pause prevented North Korean hackers from using cross-chain swaps to launder the assets.
