Zano rolls back a month of transactions as team plans to use personal funds for recovery

Zano’s team says it will draw on the blockchain network’s developer fund, team members’ personal funds and committed contributors to finance recovery from an emergency rollback. The rollback removed roughly a month of previously confirmed transactions from the recovered Zano chain. The team update gives no funding amount or timetable for payments.

The team says the network is stable and it is working with partners to verify affected activity. ZANO supply and emission will remain unchanged, it said. The named sources are a funding plan, not a published guarantee that every loss will be covered. Eligibility rules and a claims process have yet to be released.

Zano’s emergency release, published Sept. 27, restarted the chain from block 3,833,000, which the release dates to Aug. 26 at 15:50 UTC. Transactions recorded on the previous chain after that point are absent from the recovered chain.

The core team said a Gateway Address vulnerability had allowed unauthorized ZANO and Freedom Dollar, or fUSD, to enter circulation. It reported no compromise of wallet spend keys or ordinary transaction privacy, while a full post-mortem remains pending. The team also said the rollback cannot undo payments already settled in USDT, DAI or other assets on separate networks. That distinction matters for a swap or trade with a Zano transaction on one side and an external payment on the other.

What affected users can do

Zano says affected users need take no claims action yet; it will publish instructions after working with partners and counterparties. Zano’s verified forum account said no claims process was live in its recent reply and advised users to save transaction IDs plus trade and exchange records. It said users can open a support ticket to put a case on record, but nobody can preapprove a claim before the rules are published.

The core team has told users to update their wallets and check a payment’s final status on the recovered chain before resending it. It is supporting exchanges, wallets and payment services as they move over, but each operator must make its own update and announce when ready. Users should confirm a service has adopted the recovered chain before sending funds to or from it.

Zano has promised a further update on wallets, services and exchanges and a post-mortem of the Gateway Address flaw. Affected users still need the separate claims instructions to know what records will count and whether the stated funding can cover their losses.
