[#ZKSwap V2 Token Listing Feedback#] Errors with ERC20 tokens

I decided to go in and check how the updated ZKSwap works, at the same time leave a review.

I transferred the test tokens from the first to the second layer, I did not see any problems.
Pairs of tokens are added, but sometimes ERC 20 tokens are not suitable for listing and I get an error.

About the appearance, I think it is quite attractive.

I wish you good luck!
