This schema defines a `MyTransfer` entity with fields such as `id`, `amount`, `source`, `designation`, and `signers`.

## Step 4: Generate Protobuf Files

To generate Protobuf objects in AssemblyScript, run the following command:

```bash
npm run protogen
```

This command converts the Protobuf definitions into AssemblyScript, allowing you to use them in the subgraph's handler.

## Step 5: Handle Substreams Data in `mappings.ts`
## Step 4: Handle Substreams Data in `mappings.ts`

With the Protobuf objects generated, you can now handle the decoded Substreams data in your `mappings.ts` file found in the `./src` directory. The example below demonstrates how to extract to subgraph entities the non-derived transfers associated to the Orca account id:

## Conclusion

You’ve successfully set up a trigger-based Substreams-powered subgraph for a Solana SPL token. You can now further customize your schema, mappings, and modules to suit your specific use case.
