DO_NOT_MERGE Exercise 6

[ashu26jha]

New Sync package using feeder gateway

[rianhughes]

Why not just use the starknetData interface? Adapting the types manually is a good exercise though

[rianhughes]

You should handle the error

[ashu26jha]

I will try to fix this through the manually, if it doesn't work I will switch to the starknetdata interface as you mentioned above!

I get it now, stateUpdate is null. That is why the memory leak error

[rianhughes]

Generally it looks pretty good, although I would recommend fixing the tests.

[ashu26jha]

Hey @rianhughes, smoke test (syncing first 100 blocks) are working 🎉, but there are some issues I would like to highlight

1. Can't fix all the lints as http is not added to ignore (could be fixed by adding //nolint comment)
2. It only works with mainnet

Should I try fixing these or move on?

PS:

I also added verifier_Task again just to have the sanity checks, this is my logs when synching:
