Abstract: Private keys are very important to blockchain users, as it verifies any transactions of one’s
crypto account. Therefore, private keys are supposed to be secret and never shared with
other users. However, private keys consist of a long string with a combination of numbers and
letters, making it very hard to remember. This paper introduces a system to store private
keys to hardware to address this issue. The implementation utilizes Arduino Nano 33 IoT as
the hardware wallet and fingerprint to secure the private keys. Therefore, users can control
and need not worry about memorizing their keys without using third-party key management
applications. The private key also can be paired with more than one fingerprint, so it can
be passed on to the owner’s heirs.
