🚨 CRITICAL SECURITY UPDATE FOR $BTC COLDCARD HARDWARE WALLETS RELEASED ⚡
🔒 Institutional self-custody protection requires absolute structural precision. Coldcard has deployed firmware updates 5.6.1 and 1.5.1Q following a three-week security audit addressing recovery phrase entropy generation. 🛡️
💡 Affected users must patch their devices, generate a fresh seed incorporating manual entropy alongside hardware TRNGs, and migrate all $BTC reserves to newly established addresses. This patch also reinforces PSBT pre-signing verification and USB protection protocols to harden institutional storage. 🔍
