Thank you for bringing this item up!
The safety and security of BENQI is the most critical aspect of our work. We have worked extensively with Ava Labs in this regard.
The EOA is currently protected in a hardened memory-only runtime environment with no remote access and extremely restricted physical access.
We are currently in the final stages of transitioning to a distributed warden system based on multiparty computation technology (MPC). We will make the details public in due course.
Note: It will still appear as an EOA, but is in fact a fragmented security solution based on distributed ECDSA.
