FAQ

Find answers to some of the most common questions.

Transaction Check® is a new Ledger security feature that proactively analyzes before you sign them. It uses simulation technology, machine learning, and real-time threat detection to assess potential risks.

This helps protect you from scams, malicious contracts, and other transaction-based threats by giving you a clear risk assessment before approval.

While no system can guarantee 100% threat prevention, Transaction Check® significantly reduces risk by flagging suspicious activity and providing insights before you sign.

It leverages blockchain simulations, threat modeling, and community data to give a probabilistic risk assessment—helping you avoid common traps like fake token swaps or malicious contract approvals.

Yes, if you own a Ledger Nano S Plus, Nano X, Stax™, or Flex™, you must enable Transaction Check® by December 5, 2025 to avoid interruptions.

However, if you purchased a Ledger Stax™ or Ledger Flex™ after September 30, 2025, Transaction Check® is already configured, no action needed.

Failing to enable Transaction Check® could lead to:

Limited access to Ledger Live
Disrupted or unavailable Clear Signing
Issues with future updates

No. Transaction Check® requires a secure internet connection to send your unsigned transaction to external simulation providers.

However, all sensitive operations like key handling and signing still happen within the Secure Element, ensuring your private keys remain offline and secure at all times.
