THORChain pauses cross‑chain swaps after an Ethereum block reorganization creates a 10 ETH shortfall
On 31 Oct 2026 a one‑block reorganization on Ethereum dropped a 10 ETH deposit that THORChain had already credited, causing an erroneous payout. The protocol’s automatic solvency checker detected the shortfall and halted ETH swaps within about two minutes, then extended the pause to ten other chains as a precaution. Chainalysis said the pause delayed the laundering of funds stolen in the recent Binance hack.
Why it matters
The emergency halt slows the use of THORChain as a cross‑chain laundering route, which could reduce illicit activity but also curtails liquidity for users of ETH and other assets (the company said the pause delayed laundering of Binance‑hack funds).
