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

There are different Substreams providers that you can use. StreamingFast and Pinax are the largest providers currently.

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!

Protobuf for the different supported chains

Protocol	Proto model	Latest package
Ethereum	sf.ethereum.type.v2.Block	ethereum-v0.10.4.spkg
NEAR	sf.near.type.v1.Block
Solana	sf.solana.type.v1.Block	solana-v0.1.0.spkg
Cosmos	sf.cosmos.type.v2.Block
Bitcoin	sf.bitcoin.type.v1.Block
Antelope	sf.antelope.type.v1.Block
Starknet	sf.starknet.type.v1.Block
Stellar	sf.stellar.type.v1.Block

EVM Extended vs Base Block Model

For EVM chains, the are two different types of Block models: Extended and Base:

• An Extended Block is produced by a full node instrumentation integration, thus containing a rich data model (balance changes, internal calls, storage changes...).

• A Base Block is produced by a RPC Poller integration, which essentially means that only the data exposed by an RPC endpoint can be included in the data model.

The following table summarizes the different data contained in each type of Block.

Base vs. Extended Block Data Available

The data missing in the Base Block makes the corresponding Protobuf field empty. For example, if you try to read internal call on a Base Block, the list will be empty.

You can support other blockchains for Substreams through Firehose instrumentation. Learn more in the official Firehose documentation.
