# Deploying

In this chapter, you'll deploy your ClownBeatdown contract to a local Seismic node for testing. By the end of this guide, you'll have a fully deployed contract that you can interact with using your CLI or scripts. *Estimated Time: \~15 minutes.*

### Writing the deploy script

Navigate to the script folder in your project and open the `ClownBeatdown.s.sol` file located at:

```bash
packages/contracts/script
```

and add the following to it:

```solidity
// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.13;

import {Script, console} from "forge-std/Script.sol";
import {ClownBeatdown} from "../src/ClownBeatdown.sol";

contract ClownBeatdownScript is Script {
    ClownBeatdown public clownBeatdown;

    function run() public {
        uint256 deployerPrivateKey = vm.envUint("PRIVKEY");

        vm.startBroadcast(deployerPrivateKey);
        clownBeatdown = new ClownBeatdown(3);
        vm.stopBroadcast();

        console.log("Deployed at:", address(clownBeatdown));
    }
}
```

This script will deploy a new instance of the ClownBeatdown contract with an initial stamina of 3. We'll add secrets separately in the next step, since `addSecret` performs shielded writes that need to be sent as on-chain transactions.

### Deploying the contract

1. In a separate terminal window, run

```bash
sanvil
```

in order to spin up a local Seismic node.

2. In `packages/contracts`, create a `.env` file and add the following to it:

```properties
RPC_URL=http://127.0.0.1:8545
PRIVKEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
```

The `RPC_URL` denotes the port on which `sanvil` is running and the `PRIVKEY` is one of the standard `sanvil` testing private keys.

3. Now, from `packages/contracts`, deploy the contract:

```bash
source .env
sforge script script/ClownBeatdown.s.sol:ClownBeatdownScript \
    --rpc-url $RPC_URL \
    --broadcast
```

The output will show the deployed contract address (e.g. `0x5FbDB2315678afecb367f032d93F642f64180aa3`).

4. Add secrets to the deployed contract using `scast send`. Replace `<CONTRACT_ADDRESS>` with the address from the previous step:

```bash
scast send <CONTRACT_ADDRESS> "addSecret(string)" "The moon is made of cheese" \
    --rpc-url $RPC_URL --private-key $PRIVKEY
scast send <CONTRACT_ADDRESS> "addSecret(string)" "Clowns rule the underworld" \
    --rpc-url $RPC_URL --private-key $PRIVKEY
scast send <CONTRACT_ADDRESS> "addSecret(string)" "The cake is a lie" \
    --rpc-url $RPC_URL --private-key $PRIVKEY
scast send <CONTRACT_ADDRESS> "addSecret(string)" "42 is the answer" \
    --rpc-url $RPC_URL --private-key $PRIVKEY
scast send <CONTRACT_ADDRESS> "addSecret(string)" "Never trust a smiling clown" \
    --rpc-url $RPC_URL --private-key $PRIVKEY
```

Your contract should be up and deployed to your local Seismic node with 5 secrets!

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.seismic.systems/tutorials/understanding-the-clown-beatdown-contract/writing-the-contract/deploying.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
