Get chain data

Immutable's Blockchain Data indexer supports multiple blockchains. The List Chains function returns a list of supported blockchains. This function is useful to get details on supported chains without need for hard coding them, and programs can use it to integrate new chains automatically.

List all chains supported by Immutable's Indexer

If a user wants to review all chains (Production and Dev) supported by Immutable’s search engine the `listChains` function should be used with the following parameters:

const ListChains = async () => {
const response = await client.listChains();
return response.result;

The result will return an array of Chain objects.
