THORChain halted trading after an Ethereum one-block reorg at 11:34 UTC on October 31 caused a vault to pay out 10 ETH it never received. A deposit sat in a dropped block, but THORChain had already credited it; the swap missed its price limit and was refunded, and the sender's real deposit was also refunded. The solvency checker halted ETH swaps automatically, and node operators stopped signing within about two minutes, then halted all chains as a precaution. The user returned the 10 ETH, restoring solvency. Trading continues on AVAX, BASE, RUNE and XRPL, while ten chains including BTC, ETH and SOL remain halted pending fixes.
