Deploying a Contract on Neon EVM with Foundry

Introduction

• Speaker: Daria, Developer Relations Engineer for Neon
• Purpose: Video walkthrough on deploying a smart contract using Neon EVM with Foundry.

Setting Up MetaMask

1. Install MetaMask:
   • Link provided in the tutorial.
2. Add Neon EVM to MetaMask:
   • Access chain list page through links in the docs.
   • Click 'Connect Wallet' to add Neon DevNet to MetaMask.
   • Switch network to DevNet.

Acquiring DevNet Tokens

• Get DevNet Tokens:
  • Navigate to the Neon faucet.
  • Connect MetaMask wallet.
  • Request 50 Neon tokens.
  • Confirm the transaction was successful.

Installing Foundry

• Installation Process:
  • Follow instructions in the Foundry book.
  • Run the curl command in the terminal to install.

Initializing the Foundry Project

1. Create Project Folder:
   • mkdir neon_test
   • cd neon_test
2. Initialize Foundry:
   • Run forge init to create project files including:
     • Deployment script
     • Counter contract
     • Test files
3. Open Project in Editor:
   • Use preferred code editor (e.g., VS Code).

Customizing the Deployment

1. Create Environment File:
   • Store environment variables (e.g., RPC URL, Chain ID, Private Key).
2. Fetch Private Key from MetaMask:
   • Go to account details, press 'Show Private Key'.
3. Populate the env File:
   • Add RPC URL, MainNet URL, Chain IDs, and Private Key.
4. Load Environment Variables:
   • Run source .env in the terminal to use the variables.

Deploying the Contract

1. Run Deployment Command:
   • Command format: forge create --rpc-url <devnet_url> --private-key <your_private_key> <contract_path> --legacy
   • Use counter.sol from the source folder for the contract.
2. Verify Deployment:
   • Check the transaction hash and deploy address in the terminal.
   • Visit Neon Scan, paste transaction hash, ensure it's set to DevNet.

Conclusion

• Successfully deployed contract on Neon using Foundry.
• Encouragement to try it out and ask questions in the comments.
• Thank you for watching!
