solidity

Solidity devs: when looking at a stack trace, what does a function call to "0x" mean? (It's an unverified contract, hence the function signatures instead of function name.)

My hunch, based on my understanding of the previous function call, is that it's call to a library - perhaps it doesn't exist. However, the functions in that library are internal, and my understanding is that the internal functions are inlined instead of it being a separate contract.

In case anyone can share insights: https://warpcast.com/jem/0x7d43e6d0

I haven't run into a stack trace with the fallback function, tbh. Not sure how it would appear!
