RUNE Rebounds as THORChain Restores Most Network Operations
THORChain's native token, RUNE, climbed roughly 15 percent over a 24-hour window on Wednesday as the cross-chain swap protocol brought back trading functionality across the majority of its supported blockchains. According to CoinMarketCap data, the asset was trading in the vicinity of $0.64 after the rally, representing a significant recovery following the disruption that had gripped the network over the weekend.
The protocol's network status dashboard confirmed that 10 out of 13 listed external networks had returned to a fully operational state, with both trading and transaction signing marked as "OK." Among the chains that regained full functionality were Bitcoin, Ethereum, Bitcoin Cash, Dogecoin, Litecoin, Tron, and Zcash. Three additional networks—Avalanche, Base, and XRP—had already been running normally at the time the initial halt was reported on Monday, meaning the core issue affected a narrower set of chains than the full roster.
However, not all networks have been fully restored. BNB Smart Chain, Cosmos Hub, and Solana continued to display warnings on both trading and transaction signing functions, indicating that engineers were still working through residual issues on those platforms before clearing them for normal operation.
How a Single-Block Reorg Triggered the Outage
The chain of events that led to the multi-day pause began on Saturday, when a one-block reorganization on the Ethereum network effectively erased a 10 Ether deposit that THORChain's vault had already credited to a user's account. Because the underlying funds had been reversed at the protocol level, the swap in question failed to satisfy its predefined price limit.
At that point, THORChain's automated refund mechanism issued a payout against funds the vault had never actually received. Compounding the problem, the sender's original deposit was simultaneously refunded as well. The net result was an unintended extra 10 ETH flowing out of the system, which in turn triggered the protocol's built-in circuit breaker and an automatic pause of trading operations.
Following the incident, node operators across the network took the precautionary step of halting trading on multiple chains while the development team investigated the root cause and confirmed that no further exposure remained. The pause persisted through the weekend before most networks were gradually brought back online, with the three remaining chains still under review as of Wednesday.
Unintended Consequences: Delaying North Korean Hackers
Beyond the technical disruption to THORChain users, the weekend halt had an unexpected ripple effect in the broader crypto security landscape. Blockchain analytics firm Chainalysis reported that the temporary freeze on cross-chain swaps had inadvertently obstructed efforts to move proceeds stolen during the $6.3 billion Binance hack. Specifically, the company noted that North Korean-linked threat actors had been attempting to launder the illicit funds through cross-chain bridges, and the THORChain pause disrupted those transfer attempts, buying investigators additional time to trace the stolen assets.
The incident underscores how a single protocol-level bug—originating from a routine Ethereum reorganization—can cascade into a multi-chain trading halt with consequences that extend well beyond the affected protocol's own user base.
