A hacker could assemble different devices in my network though, right?

We designed Gridlock so that only the user's device can access their crypto. Even if a hacker guessed your account credentials, they would be put into 'Read Only' mode, which prevents them from doing anything.
For a hacker to steal your crypto, they would need your device and the other devices in your network. The distributed nature of Gridlock ensures that hackers cannot make transactions, only your device can.
