Can you share the config section where HDWalletProvider is used? Also, note that it's generally better to share text instead of images because text is indexable enabling a better search/help experience for all users.

• Use this file to configure your truffle project. It's seeded with some
• common settings for different networks and features like migrations,
• compilation, and testing. Uncomment the ones you need or modify
• them to suit your project as necessary.
• More information about configuration can be found at:
• https://trufflesuite.com/docs/truffle/reference/configuration
• Hands-off deployment with Infura

• ---

• Do you have a complex application that requires lots of transactions to deploy?
• Use this approach to make deployment a breeze 🏖️:
• Infura deployment needs a wallet provider (like @truffle/hdwallet-provider)
• to sign transactions before they're sent to a remote public node.
• Infura accounts are available for free at 🔍: https://infura.io/register
• You'll need a mnemonic - the twelve word phrase the wallet uses to generate
• public/private key pairs. You can store your secrets 🤐 in a .env file.
• In your project root, run $ npm install dotenv.
• Create .env (which should be .gitignored) and declare your MNEMONIC
• and Infura PROJECT_ID variables inside.
• For example, your .env file will have the following structure:
• MNEMONIC = <Your 12 phrase mnemonic>
• PROJECT_ID =
• Deployment with Truffle Dashboard (Recommended for best security practice)

• ---

• Are you concerned about security and minimizing rekt status 🤔?
• Use this method for best security:
• Truffle Dashboard lets you review transactions in detail, and leverages
• MetaMask for signing, so there's no need to copy-paste your mnemonic.
• More details can be found at 🔎:
• https://trufflesuite.com/docs/truffle/getting-started/using-the-truffle-dashboard/

This is the whole config file. Mnemonic and project ID are mentioned in .env file seperately.
