"can integrated" meaning

I saw the following sentence in a paper:

Filament enables smart devices to blockchain transactions that can integrated in different distributed ledger architectures by use their Blocklet solution.

I have two questions:

1. I know "integrate" is both transitive and intransitive, but, shouldn't it be "can be integrated" when it is used after "can"?

2. What is the difference between "by use their ..." and "by using their ..."?

Solution 1:

1. You are correct. It should be "can be integrated". The paper most likely made a typographic error.
2. This again seems to be a typo. "By using their..." is the correct usage.

Hope this helps!
