Upbit placed MultiversX's EGLD under trading caution after the project confirmed an attempted virtual-machine-level atomicity exploit caused invalid state changes and halted mainnet progression. EGLD deposits and withdrawals remain suspended, with withdrawals to resume before deposits if transfers reopen. Upbit will review the asset from Sept. 21 through the fourth week of October and could extend the review or end trading support. Bithumb also suspended transfers, while Kraken moved EGLD pairs to cancel-only mode and Coinbase reported delayed sends and receives. EGLD fell from $4.14 on Sept. 18 to $3.78 on Sept. 20 as trading volume increased, although the data do not establish that the incident caused the entire decline. MultiversX is testing a recovery fix through a shadow fork and plans to publish a technical report after the response is complete.
