Deployment

Step 1: Install Hardhat.

npm install -g hardhat

Step 2: Create Example smart contract project.

mkdir example-project
cd example-project
npx hardhat init

Step 3: Make .env and input your private key.

PRIVATE_KEY=<your_private_key>

Step 4: Install dotenv module.

npm install dotenv

Step 5: Import environmental variables to hardhat.config.js.

require('dotenv').config()
const private_key = process.env.PRIVATE_KEY

Step 6: Establish endpoint settings.

By default, the script will be using your local host "127.0.0.1" - If you are not running a localhost, you may leverage the public endpoint https://testnet.cascadia.foundation/ by making changes to networks in hardhat-config.js, for example:

networks: {
    cascadia: {
      url: "https://testnet.cascadia.foundation",
      accounts: [private_key]
    }
  },

The total result code in hardhat.config.js is the following:

require('dotenv').config()
const private_key = process.env.PRIVATE_KEY
/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  solidity: "0.8.17",
  networks: {
    cascadia: {
      url: "https://testnet.cascadia.foundation",
      accounts: [private_key]
    }
  }
};

Step 7: Deploy Contract.

npx hardhat run -netork cascadia scripts/deploy.js

Step 8: Obtain contract address from console.

~/deploy-doc$ npx hardhat run --network cascadia scripts/deploy.js
Lock with 1 CC and unlock timestamp 1706489110deployed to 0xA32C3d322b9e35071c42D03237176D53e15D464

Step 9: Confirm successful deployment on Cascadia's block explorer.

Type your deployed contract address into the block explorer search bar or https://explorer.cascadia.foundation/address/<your_contract_deployed_address> to confirm successful deployment.
