I am planing to do some LiftOver from hg19 to 38. Well there is the tool and UCSC chain file. However, I roughly remember that UCSC uses zero-based coordinates, which is different from others. Will this create a problem? Should I edit ucsc chain file first by adding 1?

A given format always uses the same coordinate system. This will work perfectly fine as long as the chromosome names are compatible.
So what you mean is that the effect of 0 vs 1 will cancel out, and I shouldn't be worried about it. Is that right?

No, what I mean is that there is no difference between UCSC and anything else. A format is a format, regardless of where it's from.
Edit: Perhaps I should mention that the tool itself has 0-based coordinates in mind.
