Creating a Subgraph

Create your subgraph from scratch or an existing contract.

If you already have a subgraph and are looking to deploy it on Alchemy Subgraphs, see Deploying a Subgraph.

From Scratch

To create a subgraph from scratch:

From an Existing Contract

To create a subgraph that indexes all events of an existing contract:

shell
$graph init \
>  --product hosted-service
>  --from-contract <CONTRACT_ADDRESS> \
>  [--network <ETHEREUM_NETWORK>] \
>  [--abi <FILE>] \
>  <subgraph name>

The ABI will be fetched from Etherscan. If it can’t be found, the --abi file will need to be specified.

From an Example Subgraph

Alchemy Subgraphs has several example subgraphs for you to instantly deploy. See your dashboard to get started.
