Quick Start

Welcome to the WowChain deployment quickstart guide! This comprehensive walkthrough will help you set up your environment and deploy smart contracts on WowChain. Whether you’re a seasoned developer or just starting out, this guide has got you covered.

What You’ll Achieve

By the end of this quickstart, you’ll be able to:

• Set up your development environment to deploy on WowChain

• Deploy your smart contracts to WowChain

• Connect your frontend to your smart contracts

Set Up Your Development Environment

1. Create a new project directory

mkdir my-wow-project && cd my-wow-project

1. Install Foundry, a powerful framework for smart contract development

curl -L https://foundry.paradigm.xyz | bash
foundryup

This installs Foundry and updates it to the latest version.

1. Initialize a new Solidity project

forge init

Your Foundry project is now ready. You'll find an example contract in the src directory, which you can replace with your own contracts. For the purposes of this guide, we'll use the Counter contract provided in /src/Counter.sol

Configure Foundry

To deploy your smart contracts to WowChain, you need two key components:

1. A node connection to interact with the WowChain network

2. A funded private key to deploy the contract

Let's set up both of these:

1. Set up your node connection​

1. Create a .env file in your project's root directory

2. Add the WowChain network RPC URL to your .env file

WOW_RPC_URL="https://rpc.wowchain.io"

1. Load your environment variables

source .env

2. Secure your private key​

1. Store your private key in Foundry's secure keystore

cast wallet import deployer --interactive

1. When prompted enter your private key and a password.

Your private key is stored in ~/.foundry/keystores which is not tracked by git.

Deploy Your Contracts​

Now that your environment is set up, let's deploy your contracts to WowChain Mainnet.

1. Use the following command to compile and deploy your contract

forge create ./src/Counter.sol:Counter --rpc-url $WOW_RPC_URL --account deployer

Note the format of the contract being deployed is <contract-path>:<contract-name>.

1. After successful deployment, the transaction hash will be printed to the console output

2. Copy the deployed contract address and add it to your .env file

COUNTER_CONTRACT_ADDRESS="0x..."

1. Load the new environment variable

source .env

Verify Your Deployment

To ensure your contract was deployed successfully:

1. Check the transaction on WowChain Explorer.

2. Use the cast command to interact with your deployed contract from the command line

cast call $COUNTER_CONTRACT_ADDRESS "number()(uint256)" --rpc-url $WOW_RPC_URL

This will return the initial value of the Counter contract's number storage variable, which will be 0.

Congratulations! You've deployed your smart contracts to WowChain Mainnet!
