Overview

DipDup is a Python framework for building smart contract indexers. It helps developers focus on business logic instead of writing a boilerplate to store and serve data. DipDup-based indexers are selective, which means only required data is requested. This approach allows to achieve faster indexing times and decreased load on underlying APIs.

Understanding DipDup​

DipDup is a software framework that helps web3 developers create selective indexers for decentralized applications. It uses blockchain data provided by various off-chain data sources. Some of the key features of DipDup include:

  • Ready for multichain: DipDup supports dozens of blockchains, and we are constantly adding new ones. You can easily reuse your business logic for different networks or even index multiple chains in a single project.
  • Declarative configuration: A whole indexer is defined by a single configuration file and a bunch of Python data handlers. Code is completely separated from the configuration and environment variables, making it easy to maintain and deploy your project.
  • Integrations: You can use SQLite, PostgreSQL, or TimescaleDB databases to store blockchain data, deploy to Compose or Swarm with a single command, monitor your indexer with Prometheus or Sentry, and more.
  • GraphQL API: DipDup automatically generates a GraphQL API for your data using Hasura, so you can query it from your frontend or other services. You can extend the API with custom queries and metadata requests.
  • CLI: DipDup CLI has everything you need to conveniently manage your project, from creating a new one to running and deploying. There are lots of templates for various blockchains and use cases, so you can start quickly.
