Chains and endpoints

StreamingFast Substreams chains and endpoints

Chains and endpoints overview

The different blockchains have separate endpoints that Substreams uses. You will use the endpoint that matches the blockchain you've selected for your development initiative.

Supported blockchains and protobuf models

Protobuf definitions and public endpoints are provided for the supported protocols and chains.
Tip: All of the endpoints listed in the documentation require authentication before use.
Important: Endpoints serve protobuf models specific to the underlying blockchain protocol and must match the source: field for the module.
Streaming a sf.near.type.v1.Block from an Ethereum endpoint does not work!
