 ## Querying the Chain
 
-On Flow, you can interact with a contract by reading from the chain with a script or changing its state with a transaction. Reading is free and is done with FCL by passing a Cadence (the smart contract language of Flow) script to `fcl.query`. For our example we are going to read from a `HelloWorld` contract deployed to the account `0x9dca641e9a4b691b` on `testnet` (you can [view the contract here](https://f.dnz.dev/0x9dca641e9a4b691b/HelloWorld) to see what it looks like).

 In the same `src/App.js` file, let's create app state to store our greeting and query the chain when the component renders in order to fetch the greeting state from the `HelloWorld` contract.
