iPhone 17’s MIE Feature Enhances Crypto Wallet Security with Hardware-Level Protections

Apple's iPhone 17 introduces Memory Integrity Enforcement (MIE), a hardware-software security feature designed to thwart memory-based attacks during crypto wallet transactions. Powered by the A19 chip and Enhanced Memory Tagging Extension (EMTE), the system detects and blocks exploits like buffer overflows in real-time—addressing 70% of software vulnerabilities exploited in wallet breaches.

Cobo founder DiscusFish highlights MIE's significance for high-net-worth crypto users and frequent signers, as it eliminates manual setup while providing always-on protection. The feature specifically hardens the signing process, a prime target for asset theft. Apple further mitigates side-channel risks with Tag Confidentiality Enforcement (TCE), creating a multilayered defense for digital asset security.
