Architecture

This monorepo contains the following components:

1. frontend: A web frontend for Moonstream. Allows users to create dashboards and monitor the activity of accounts and smart contracts on multiple blockchains. Built in React.
2. backend': The Moonstream API allows users to programmatically consume data about transactions and events taking place on blockchains crawled by Moonstream. Built in Python using Fast API.
3. crawlers: This part of the code base contains workers which extract data from blockchains, transaction pools, and other sources. We have many crawlers and each crawler can utilize a different tech stack.
4. db: Moonstream stores blockchain data in Postgres. This directory contains the code we use to manage the schema in our Postgres database. For sources that send higher volumes of data, we use a separate Postgres database and interface with it using Bugout.
