Hi Fireblocks,

Does Fireblocks SDK support armeabi-v7a architecture? Cause when I tried to run the app on device with armeabi-v7a processor Fireblocks SDK crashed with following exception:

Hi @dendan, as per the minimum requirements, you will need a `64-bit` mobile device (usually devices with at least 6GB of RAM).

The armeabi-v7a processor is a 32-bit processor and therefore does not meet the minimum requirements.
