THORChain Briefly Halts 10 Chains After a Weird Ethereum Reorg
Nov 2, 2026
THORChain paused trading on ten chains after an Ethereum reorg triggered a phantom 10 ETH payout — the user sent the funds back and vaults are solvent again.
A Reorg Nobody Saw Coming
THORChain had a rough start to the week. On November 2, the protocol halted trading across ten different blockchains after an Ethereum block reorg triggered something nobody really expects to see: a vault sent out 10 ETH for a deposit that, because of the reorg, technically never happened.
That's the kind of edge case that keeps DeFi engineers up at night. A reorg flips a block that was already considered final, and suddenly the accounting doesn't match reality anymore. THORChain's node operators did the responsible thing and froze everything while they figured out whether the network was actually short on funds.
Problem Solved, Mostly
The good news: the user on the other end of that phantom deposit voluntarily sent the 10 ETH back, and THORChain's vaults are solvent again. A handful of chains, including AVAX, BASE, RUNE and XRPL, stayed live the whole time, and the rest are coming back online as soon as operators confirm everything is safe.
It's a small incident in dollar terms, but a useful reminder that even "final" blocks aren't always final, and cross-chain protocols have to plan for that.
