-import a reactive android library to handle the reactive stream being passed into your module.  For instance I used the following:
-
-
-    implementation 'io.reactivex.rxjava2:rxandroid:x.y.z'
-    implementation 'io.reactivex.rxjava2:rxkotlin:x.y.z'
 
 
 Optional: Call `ApiKey.takeOff.setApiKey("[your api key here]")` in your module's application class when recording api usage in the etherscan.io console. [see [example implementation](https://github.com/EbenezerGH/etherscan-android-api/blob/master/etherscan-sample/src/main/java/jfyg/etherscan/helloetherescan/EtherscanSampleApplication.kt)]
