 If you are interested in any of those chains, integration is a matter of Graph Node configuration and testing.
 
-If you are interested in a different chain type, you will need to build a new integration with Graph Node. Our recommended approach is development of a Firehose for the chain, and then integration of that Firehose with Graph Node.

 If the blockchain is EVM equivalent and the client/node exposes the standard EVM JSON-RPC API, Graph Node should be able to index the new chain. For more information, refer to [Testing an EVM JSON-RPC](new-chain-integration#testing-an-evm-json-rpc).
 
 **2. Firehose**
 
-For non-EVM-based chains, Graph Node will need to ingest blockchain data via gRPC and known type definitions. This can be done via [Firehose](firehose/README/), a new technology developed by [StreamingFast](https://www.streamingfast.io/) that provides a highly-scalable indexing blockchain solution using a files-based and streaming-first approach.
