GraphQL Data Sources and Indexers

Blockchain developers are often faced with the challenge of obtaining data from various API and data sources. Traditional methods may involve directly interacting with each network's API, which can be time-consuming and complex. However, leveraging GraphQL data sources simplifies this process, enabling developers to fetch data from multiple sources seamlessly.
