IoTex Suffers Massive $4.4M Hack Through Flawed ioTube Bridge

IoTex's cross-chain bridge, ioTube, was targeted in a $4.4M hack in February 2026. Halborn investigates. EIP-3529 security measures were supposedly implemented by IoTeX but failed to prevent the breach. The incident demonstrates the vulnerability of DeFi bridges despite claimed security updates. IoTeX has since paused all bridge operations to assess damage and implement new protections.
