Sample app

What is this app for?

Here is Console app to get block and transaction information from Etherscan Provider and store it in MYSQL database.

Infrastructure

This app was built against following there layers model

• Application layer
• Service layer
• Data access layer ( with help of EF Core)

Setup

• Create db using docker by running this command docker run -p 3306:3306 --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:latest
• Create new account on Etherscan , grab the api key and replace those key with [YOUR_API_KEY] in appsettings.json file
• Then execute the executable file - Sample.exe. That's it.

Pros

• Apply TDD
• Apply retry-pattern

What to enhance?

• Should apply some job service to retry the failed block or transaction stuff if there is some transient network issue
• Should apply some notification service to send a notification if there some request failed to Etherscan

Happy coding :)
