Zano disclosed a validation flaw in the Gateway Addresses introduced by Hard Fork 6. An attacker minted approximately 18.4 million ZANO in a single transaction on August 29, then minted an equal amount again on September 25, and minted fUSD in the same manner.The project team stated that the value of the illicit tokens involved exceeds $200 million, with potentially affected activity involving 117,941 outputs and 65,301 transactions. Zano has restored the chain state from block 3,833,000 and disabled Gateway Addresses. All affected balances will be fully restored, and the ZANO supply and issuance schedule will remain unchanged.

According to The Block (@TheBlockCo), the Zano network was recently subjected to a Gateway Address vulnerability attack, resulting in the unauthorized minting of ZANO and fUSD that have since entered the market. To contain the losses, the team has urgently restarted the blockchain. The team is currently actively negotiating with affected projects and relevant counterparties regarding compensation for losses, and will publish a formal compensation and claims process in the near future.
privacy blockchain project Zano has rolled back its blockchain to block height 3,833,000, before the 6th hard fork, deleting approximately one month of on-chain transaction records in order to address an inflation vulnerability involving Gateway Addresses.The vulnerability allowed unauthorized minting of the native token ZANO and the USD-pegged stablecoin fUSD. Zano stated that the core consensus protocol, wallet spending keys, and ordinary transaction privacy were not affected, and that nodes, miners, stakers, and service providers need to adopt the update.Freedom Dollar stated that millions of dollars in assets held by the project had been swapped into counterfeit fUSD, and that the related losses will be borne by the project. Freedom Dollar has asked fUSD holders to suspend economic activity involving the token until the stabilized Zano chain is confirmed after repairs. (Bitcoin.com News)
Odaily reports: Privacy blockchain network Zano has disclosed that an inflation vulnerability involving Gateway Addresses has forced it to plan a rollback of approximately 24 hours of blockchain history, and has urged users to immediately cease all economic activity related to ZANO and Confidential Assets.Zano has promised to compensate for losses caused by the rollback, but has not yet announced the target block height for the rollback, the patched version, the compensation process, the mechanics of the vulnerability, or the amount of unauthorized assets created. Gateway Addresses went live on August 26 with Hard Fork 6. (Bitcoin.com News)
Coinbase, a cryptocurrency trading platform, has disclosed in a technical sharing session that its internal multi-agent development tool "Mux" is reshaping software engineering workflows, transitioning the engineer's role from traditional code implementers to task orchestrators for AI agents.With the widespread internal adoption of AI programming tools such as Cursor, Copilot, OpenCode, and Claude Code, code generation efficiency has significantly improved. However, development workflows have long remained stuck in a traditional "single-task, single-branch, sequential execution" mode, creating a new collaboration bottleneck.Mux was born as an internal tool against this backdrop. By assigning each AI agent an independent git worktree, branch, and terminal environment, the system enables parallel multi-task development and conflict-free collaboration, allowing engineers to simultaneously direct multiple agents to handle tasks such as API development, test writing, vulnerability fixes, and code refactoring.Data shows that as of April 2026, Mux has covered over 600 users within Coinbase (including engineers, product managers, and designers), with 335 actively using it and 197 being high-frequency users. It has facilitated over 5,000 PR merges across 461 code repositories and 10 organizations. Engineers using Mux achieved an average of 39.6 PR merges, approximately 3.5 times the baseline of 11.4.Coinbase stated that Mux's success relies on its internal infrastructure capabilities, including an LLM Gateway, secure model access, and a code flow deployment system, enabling deep integration of multi-agent tools into real development workflows. This trend marks a structural shift in the software engineering paradigm: as AI reduces the cost of code generation, the core value of engineers is transitioning from "implementation capability" to "problem definition and agent orchestration capability."
According to an official disclosure by Hyperbridge, the losses from the Token Gateway vulnerability incident on April 13 have been revised upward from an initial estimate of $237,000 to approximately $2.5 million. The increase stems primarily from losses incurred in incentive pools on Ethereum, Base, BNB Chain, and Arbitrum. The attacker extracted roughly 245 ETH from related contracts, then bypassed the MMR proof verification mechanism by forging cross-chain messages, minting 1 billion bridged DOT tokens and dumping them onto illiquid markets. Currently, some of the stolen funds have been traced on-chain to Binance. Hyperbridge is collaborating with Binance’s compliance team and law enforcement agencies to investigate the incident. Polkadot-native DOT and products such as Intent Gateway remain unaffected. The Token Gateway and bridged DOT contracts on the four affected EVM chains remain suspended. An external audit of the patched MMR verification logic is underway, and bridging functionality will be restored upon completion of the audit.
According to PeckShieldAlert monitoring, approximately 1 billion Polkadot (DOT) tokens have been minted and dumped on the Ethereum network. Details of the incident are still under further verification. According to CertiK monitoring, the Hyperbridge gateway contract was attacked; the attacker forged messages to tamper with the admin privileges of the Polkadot token contract on Ethereum, and profited approximately $237,000 by minting and selling 1 billion tokens.
