THORChain Halts Trading After Suspicious Multi-Chain Transfers Surface

On-chain investigator ZachXBT first reported suspicious transfers tied to THORChain wallets on Friday. Blockchain data later showed assets moving across several networks. This includes Bitcoin, Ethereum, BNB Chain, and Base.
According to the reports, wallets linked to the exploit currently hold around 36.85 BTC, 3,443 ETH, and 96.6 BNB.

THORChain later paused trading and signing operations through its Mimir governance module. Meanwhile, node operators activated a temporary network halt. The protocol has not yet released a post-mortem explaining how the exploit happened.
RUNE fell between 12% and 15% following the news, dropping from around $0.58 to nearly $0.50, according to recent data.

Cross-Chain Protocols Remain a Major Target for Exploits
THORChain operates as a decentralized cross-chain liquidity network that allows users to swap native assets across different blockchains without using wrapped tokens or centralized bridges. Cross-chain infrastructure has remained one of the most targeted sectors in decentralized finance over the past few years. According to a report from Chainalysis, bridge and cross-chain related exploits have accounted for more than $2.8 billion in losses since 2021.
The latest incident adds to a growing list of security breaches affecting DeFi protocols this year. Earlier in 2026, Drift Protocol and KelpDAO were also linked to major exploit-related losses.
At the time of writing, THORChain had not publicly confirmed the exact amount stolen or provided details about the attack vector. Investigators continue tracking wallets connected to the exploit across multiple chains.
