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:

packages/contracts/script

and add the following to it:

// 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);
        clownBeatdown.addSecret("The moon is made of cheese");
        clownBeatdown.addSecret("Clowns rule the underworld");
        clownBeatdown.addSecret("The cake is a lie");
        clownBeatdown.addSecret("42 is the answer");
        clownBeatdown.addSecret("Never trust a smiling clown");
        vm.stopBroadcast();
    }
}

This script will deploy a new instance of the ClownBeatdown contract with an initial stamina of 3 and populate it with 5 secrets.

Deploying the contract

1. In a separate terminal window, run

sanvil

in order to spin up a local Seismic node.

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

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.

1. Now, from packages/contracts, run

source .env && sforge script script/ClownBeatdown.s.sol:ClownBeatdownScript --rpc-url $RPC_URL --private-key $PRIVKEY --broadcast --skip-simulation

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