THORChain Halts Trading After Suspected $10–11 Million Multi-Chain Exploit

The protocol remains paused pending a full incident report.

Overview

  • ZachXBT, who raised the alarm Friday, said at least $10 million was drained across Bitcoin, Ethereum, BNB Smart Chain, and Base.
  • THORChain triggered a global emergency halt that paused swaps and outbound signing to contain losses, while the chain itself and RUNE transfers kept running.
  • Arkham Intelligence and PeckShield flagged attacker wallets now holding about 3,443 ETH, 36.85 BTC, and 96.6 BNB, with additional funds in stablecoins.
  • RUNE fell roughly 10% to 15% after the alert, and trading activity jumped as spot volume climbed and futures open interest rose.
  • As of Sunday, trading remains paused and no technical post‑mortem has been published, underscoring persistent risks for cross‑chain protocols and THORChain’s history of prior incidents.
