 Let's now write a script for deploying your contracts to the Sandbox. We'll create an RPC client, and then use the `ContractDeployer` class to deploy our contracts, and store the deployment address to a local JSON file.

-Now we will import the contract artifacts we have generated plus the dependencies we'll need, and then we can deploy the contracts by adding the following code to the `src/deploy.mjs` file. Here, we are using the `ContractDeployer` class with the compiled artifact to send a new deployment transaction. The `wait` method will block execution until the transaction is successfully mined, and return a receipt with the deployed contract address.

 Note that the token's `_initialize()` method expects an `owner` address to mint an initial set of tokens to. We are using the first account from the Sandbox for this.
