DAI Transaction tracker

Apr 2023 - May 2023

I have an interest in web3 and smart contract technology so I wanted to do a side project to understand this better.

  • I built a docker container that listens to the DAI smart contract & submits data to a containerised postgres instance about the send, receiver & amount.
  • I then created a backend API that allows users to fetch the top 10 senders in the past 24 hours.
  • I then went on to create an api for managing blacklist records, these allow users to blacklist a wallet address meaning they wont be accounted for in the top 10 API call.
  • Kubernetes cluster to run the local images for the service & db
  • Full jest unit testing both unit & integration tests.
