Firmware Update
Required
Protect your crypto. Update your Tangem App & Firmware now.
We have identified a potential security risk in older firmware versions. To ensure maximum security, please update to the latest version and migrate your wallet now.
Why This Update Matters
Your security is our top priority. Here's what you need to know.
Security Advisory: Firmware Version 2.05.12 or Earlier
Older firmware builds may not guarantee the highest level of entropy (randomness) during private key generation. While the secure chip remains protected, updating ensures your keys are generated with maximum cryptographic strength.
The Risk
Private keys generated with lower entropy could theoretically be vulnerable. While no compromises have been reported, proactive updates eliminate this risk entirely.
After Update
Your new wallet keys will be generated with full cryptographic protection, leveraging the EAL6+ certified secure chip's maximum security capabilities.
