base_mainnet substreams modules

This package was initialized via substreams init and is being updated with custom modules to support the Base Mainnet blockchain streaming service using substreams.

Nodes available for streaming:

https://docs.substreams.dev/reference-material/chains-and-endpoints

Usage

substreams build
substreams auth
substreams gui       			  # Get streaming!

Optionally, the substreams package can be published to the Substreams Registry

https://substreams.dev/packages/substreams-base-main/v0.1.1

substreams registry login         # Login to substreams.dev
substreams registry publish       # Publish your Substreams to substreams.dev
