Before

After

Motivation

Attempted to check an address of mine that only has ETH. Because of the token empty default line, it fails a number conversion in decimals and breaks.

Dependencies

None

How has this been tested?

• Manual testing was done on my own address. The current tests require a mock to be added with this edge case state. Added unit test and cassete in ethplorer_model.
