THORChain, the decentralized cross-chain liquidity protocol, has officially resumed swapping operations on 11 external blockchains following the deployment of version 3.21.1. The restoration of services comes after an emergency halt triggered by a refund bug related to an Ethereum (ETH) block reorganization. The pause inadvertently interrupted the movement of funds associated with a recent $6.3 billion Binance exploit, which authorities have attributed to the North Korean hacking collective TraderTraitor (Lazarus Group).
Network Recovery and Node Synchronization
According to official communications from the project, the latest software patch has enabled swaps for AVAX, BASE, BCH, BTC, DOGE, ETH, LTC, RUNE, TRON, XRPL, and ZEC. However, the recovery is currently partial, as three major networks—ATOM, BSC, and SOL—remain suspended. The protocol’s team emphasized that while many services are back online, 14 active nodes have yet to upgrade to the new version.
- All active nodes must complete the 3.21.1 upgrade to resolve lingering swap performance issues.
- The protocol currently operates with 111 active nodes securing the network.
- Trading on Solana and BNB Smart Chain will remain restricted until node operators deem them safe for reactivation.
Impact on Stolen Funds and Privacy Coin Integration
The temporary suspension of the protocol had a significant impact on illicit financial flows. Blockchain analytics firm Elliptic and security researchers tracked addresses linked to the Binance hacker, finding that the emergency pause effectively delayed the laundering process. However, once trading reopened on November 4, 41 swaps related to the hacker were completed within a 25-minute window, totaling approximately 368 ETH.
THORChain has historically maintained a stance of protocol neutrality, operating as a permissionless infrastructure that does not internally censor specific addresses, leaving such decisions to individual node operators.
Beyond security fixes, the 3.21.1 update represents a technical milestone for the ecosystem's roadmap. The developers stated that this release brings the protocol "one step closer" to the highly anticipated launch of Monero (XMR) support.
This update brings THORChain one step closer to launching Monero.
The integration of XMR is expected to undergo a "soft launch" phase featuring shallow liquidity and extensive testing due to the complexity of the privacy coin's signing algorithm.
In conclusion, while the majority of THORChain's bridges have returned to functionality, the network remains in a phase of stabilization. The successful mitigation of the Ethereum reorg bug protects the protocol's solvency, but the continued suspension of Solana and Cosmos highlights the ongoing challenges of maintaining a decentralized cross-chain environment. Investors and users are advised to monitor official node status dashboards as the remaining 14 nodes synchronize with the latest security standards.
