🔍 What is Transaction Simulation—and why does it matter? Just because a transaction looks safe doesn’t mean it is. With Ledger’s Transaction Check, your transaction is: ✅ Simulated using real blockchain state. ✅ Analyzed by 3 trusted providers — Blockaid, 🚨 Cyvers Alerts 🚨 & Tenderly — to detect hidden threats. ✅ Verified on your device to prevent malware swaps. 🛡️ Results are shown directly on your secure screen—before you sign. Security, the Ledger way. 🎥 Walk through the tech with our CTO Charles Guillemet below👇
