Zano Rolls Back Month of Transactions, Names Funding Sources

Zano’s core team published an emergency release on Sept. 27 that restarted the chain from block 3,833,000, a block the update dates to Aug. 26 at 15:50 UTC. Transactions confirmed on the prior chain after that block no longer appear on the recovered ledger.

The release attributes the rollback to a Gateway Address vulnerability that allowed unauthorized ZANO and Freedom Dollar (fUSD) tokens to enter circulation. The update reported no compromise of wallet spend keys or ordinary transaction privacy and described the network as stable while staff work with partners to verify affected activity.

The funding plan names three sources: the network developer fund, personal contributions from team members and committed contributors. The announcement did not include amounts, eligibility criteria or a timetable for claims. The plan is presented as a funding approach rather than a guarantee that every loss will be covered. ZANO supply and emission will remain unchanged after the rollback.

The rollback cannot reverse payments already settled on other networks in assets such as USDT or DAI. That limitation affects users who completed swaps or trades that paired a Zano transaction with an external payment. Users were advised to update wallets and to check a payment’s final status on the recovered chain before resending funds.

Zano is providing technical support to exchanges, wallets and payment services as they adopt the recovered chain. Each operator must implement updates and announce when it is ready to resume normal service.

Zano’s verified forum account posted that “no claims process is live” and urged users to preserve transaction IDs and trade and exchange records. The account recommended opening a support ticket to put a case on record but warned no claims can be preapproved until full rules and a process are published. A post-mortem on the Gateway Address flaw is pending.

The core team plans to publish a follow-up with details on wallets, services, exchanges and the claims process once coordination with partners is complete. Until then users should confirm any service has adopted the recovered chain before sending or receiving funds and keep records that may be needed for later verification.
