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

The Zano team has announced plans to utilize the network’s developer fund, personal money from team members, and dedicated contributors to finance the recovery following an emergency blockchain rollback. This rollback wiped out roughly a month of previously verified transactions from the restored Zano chain. However, the update from the team did not provide a specific funding amount or a timeline for when payments will be distributed.

According to the team, the network has stabilized and they are currently collaborating with partners to review impacted activity. They also noted that ZANO supply and emission levels will stay the same. The listed funding sources represent a recovery strategy rather than a formal guarantee that all losses will be fully reimbursed, as specific eligibility guidelines and a claims procedure have not yet been established.

Published on Sept. 27, Zano’s emergency release rebooted the chain starting from block 3,833,000, which corresponds to Aug. 26 at 15:50 UTC. Any transactions logged on the older chain subsequent to that timestamp are missing from the current, recovered chain.

Core developers explained that a vulnerability in the Gateway Address let unauthorized amounts of ZANO and Freedom Dollar (fUSD) enter circulation. They confirmed that ordinary transaction privacy and wallet spend keys remained uncompromised, though a comprehensive post-mortem report is still forthcoming. Furthermore, the team pointed out that the rollback cannot reverse payments that were already finalized using USDT, DAI, or other assets on independent networks. This distinction is crucial for swaps or trades involving a Zano transaction on one end and an external asset payment on the other.

What affected users can do

Zano states that impacted users do not need to take any action regarding claims at this moment; instructions will be released after coordination with partners and counterparties concludes. In a reply from Zano’s verified forum account, the team noted that no claims process is currently active and advised users to preserve trade, exchange records, and transaction IDs. Users may open a support ticket to officially log their case, but claims cannot be preapproved prior to the official release of the rules.

The core team instructed users to update their software wallets and verify the ultimate status of any payment on the restored chain before attempting to resend it. While Zano is assisting exchanges, wallets, and payment services with the transition, each platform operator must complete its own updates and announce when they are ready. Users are advised to verify that a service has fully integrated the recovered chain before transferring funds to or from it.

Zano has committed to delivering an additional status update concerning exchanges, wallets, and services, alongside a detailed post-mortem analysis of the Gateway Address security flaw. Affected users must still wait for dedicated claims instructions to determine which records will be accepted and whether the announced funding pool will be sufficient to cover their individual losses.
