Fact Check
Multiple authoritative and directly relevant sources confirm that IoTeX permanently froze approximately 45 million IOTX tokens following an exploit involving their ioTube bridge. Official statements from the IoTeX account and its co-founder provide primary confirmation of the token freeze and security responses. The freeze is corroborated through blockchain explorer data and consistent reporting by reputable crypto news outlets. Additionally, independent coverage from several trustworthy sources notes that IoTeX implemented a mainnet upgrade to version 2.3.4 after the incident, which aligns with statements describing the upgrade as a measure to address and contain the exploit. There is no credible source contradicting these claims, and the actions—both freeze and mainnet restoration—are described in consistent detail across official and reputable reports. The exploit is explicitly tied to ioTube in the majority of sources, reinforcing the linkage. Based on the coherence, specificity, and authority of the evidence, the statement is highly likely to be accurate.
Summary

IoTeX reported restoring Mainnet v2.3.4 on Feb. 24 and freezing 45 million IOTX following the ioTube exploit that caused about $4.4 million in bridge losses. Attackers minted 410 million CIOTX; 99.5% is locked or frozen and 0.4% was sold via DEX. The sale proceeds were moved to 2,183 ETH and then 66.78 BTC across four monitored addresses. The IoTeX Foundation stated it will 100% compensate affected users.

Terms & Concepts
  • IOTX: The native token of the IoTeX blockchain used for transactions, staking, and governance.
  • CIOTX: A bridged representation of IOTX used via ioTube for cross-chain liquidity; attackers minted CIOTX during the exploit.
  • DEX: A decentralized exchange where users trade crypto assets directly via smart contracts without centralized intermediaries.
