Recovery Update: ZANO and fUSD Reconciliation with MEXC

Summary

This is an update on the recovery process described in the Hard Fork 7 post-mortem, The Gateway Address Vulnerability: What Happened and What Comes Next. The MEXC and Zano teams have completed reconciliation of ZANO and fUSD on MEXC. ZANO and fUSD deposits made during the affected period remain credited. Withdrawals to other exchanges and services are being re-sent, and withdrawals to personal wallets are being credited to MEXC accounts. Deposits, withdrawals, and trading in ZANO and fUSD have resumed on MEXC.

Why this was needed

The network upgrade continued the chain from block 3,833,000, so activity made between 26 August and 27 September is not part of the updated chain. As a result, various MEXC deposits and withdrawals were affected. Together with MEXC, we reviewed anonymized records to align balances with the updated chain.

Deposits to MEXC

ZANO and fUSD deposits made to MEXC during the affected period remain credited. The Zano team has provided the ZANO to reconcile these balances and is providing the fUSD. Deposits that MEXC had not yet credited remain uncredited. Those coins are back in the originating wallet on the updated chain.

The comprehensive review identified two significant outlier ZANO deposits that occurred immediately after the exploit. MEXC will not be crediting these deposits.

Note: If these deposits were generated from valid protocol consensus, the coins have been returned to the origination wallet on the updated chain. In any case, if coins have not been properly updated within your wallet, please contact the Zano team at [email protected] for further review.

Withdrawals to other exchanges and services

MEXC has re-sent ZANO and fUSD withdrawals to other exchanges and services. If you withdrew ZANO or fUSD from MEXC to another platform during that period, no action is required. The original transaction IDs of these withdrawals are listed at the end of this post.

Withdrawals to personal wallets

MEXC is crediting coins from self-custody withdrawals back to each user's MEXC account. If you withdrew ZANO or fUSD from MEXC to a self-custody wallet during the affected period, please confirm your MEXC balance once the updates have been processed.

What's next

The team is working with other exchanges and services and will post relevant updates.

If you observe any discrepancies with your records, please contact [email protected] or visit the Zano support page.
