Blockchain project IoTeX has announced that its L1 mainnet resumed stable operations on February 23, 2026. Following the recent security incident, the team activated an emergency response protocol, conducted a comprehensive system review, and deployed critical upgrades to reinforce network resilience.
According to the official disclosure, the network has been upgraded to version v2.3.4, introducing a default malicious address blacklist mechanism as a core enhancement. This mechanism automatically identifies and filters high-risk externally owned accounts (EOAs), strengthening security protections at the protocol level. Through predefined blacklist rules combined with dynamic updates, the system can intercept suspicious address interactions before abnormal activity escalates, thereby reducing potential attack surfaces.
IoTeX stated that the successful mainnet restoration was made possible through coordinated efforts between core developers and community representatives. Following the upgrade, network operations have stabilized and key infrastructure components have been fully reinforced. The team is also advancing a compensation plan for affected bridge users, with detailed arrangements expected to be released within 24 hours.
As multi-chain ecosystems and cross-chain interactions become increasingly frequent, isolated patches or single-version upgrades are no longer sufficient to address all risk scenarios. Beyond protocol-level reinforcement, continuous on-chain monitoring and dynamic risk identification frameworks are equally essential.
By integrating professional on-chain risk control systems such as Trustformer KYT, platforms can monitor abnormal address behavior, large transaction fluctuations, and cross-chain asset movements in real time, establishing a dual-layer security strategy that combines technical upgrades with proactive monitoring.
Amid tightening regulatory scrutiny and recurring security incidents across the industry, blockchain networks must build not only rapid response capabilities but also sustainable long-term risk management systems. By aligning mainnet technical upgrades with real-time fund tracing and monitoring solutions like Trustformer KYT, institutions can enhance compliance standards and operational security.
The restoration and upgrade of the IoTeX L1 mainnet demonstrate a proactive commitment to addressing security challenges. As the compensation framework is finalized and further transparency measures are implemented, the market will continue to assess IoTeX’s long-term strategy in network security and risk governance.
