If function can return err should we always check it's return value?

Just general question. Some functions can return errors, like setupTransaction. But it is not always checked. Should it be enforced or can be ignored sometimes?

Line 274 in d048ca2

this.setupTransaction({});

Good question. Most cases, it can be ignored. In this scenario, however, it might be helpful to enforce it since all we're trying to do is return fee information without subsequent calls to correct it or return an error.
