# GraphQL

The Spydra Hyperledger Fabric Base Contract has various utility methods which provide additional functionalities out of the box to any Chaincode that is deployed in a Spydra blockchain network. Simply extend your own Chaincode Smart Contract from the Spydra Base Contract to get these additional features.

Query the world state using GraphQL. For more details, refer to [GraphQL](/products-overview/private-network/graphql.md)

### Golang

1. Run `go get`

```
$ go get -u github.com/spydra-tech/fabric-contract-go/spydracontract
```

2. Extend your Smart Contract from the Spydra Base Contract

```
type MyCustomContract struct {
    spydracontract.BaseContract
}
```

3. [Deploy](https://docs.spydra.app/how-to/apps/deploy-app) the Chaincode on a Spydra Blockchain network and start querying on any attribute using [Graph QL](https://docs.spydra.app/products-overview/graphql).
