After deploying your contract to the Vector Smart Chain mainnet, the next step is to verify it on the official VSC Block Explorer. Verification allows anyone to view, read, and interact with your contract’s source code directly through the explorer interface, increasing transparency and trust.

Why Verify?

• Builds trust with your community and users.
• Makes it easier for developers and auditors to review your code.
• Enables direct contract interaction (read/write) via the VSC Block Explorer.
• Helps prevent scams or copycats by proving authenticity.

Steps to Verify Your Contract

1. Navigate to the Explorer

   Go to: https://explorer.vscblockchain.org

2. Locate Your Contract

   • Paste your contract address into the search bar.
   • Open the contract’s page.

3. Start Verification

   • On the contract’s page, click “Verify and Publish”.
   • Fill in the following details:
     • Compiler Type: Solidity (Single file or Multi-file depending on your project).
     • Compiler Version: Match the exact version used during compilation.
     • EVM Version: Usually default, unless you specified one.
     • Optimization Settings: Must match your deployment configuration (on/off, runs).

4. Submit Source Code

   • Paste or upload your contract’s Solidity code.

   • If using Hardhat or Foundry, you can generate flattened code for easier submission:

     # Hardhat flatten
     npx hardhat flatten > FlattenedContract.sol
     
     # Foundry flatten
     forge flatten src/MyContract.sol > FlattenedContract.sol
     
     

5. Confirm Verification

   • Once verified, the contract’s page will show the source code and a green “Verified” badge.
   • You will now be able to interact with functions under the “Read” and “Write” tabs directly from the explorer.

Pro Tip: Automated Verification

For larger projects, you can automate contract verification using Hardhat or Foundry plugins with the explorer’s API. This saves time when deploying multiple contracts.

• Hardhat Plugin (example config):

  require("@nomicfoundation/hardhat-verify");
  
  module.exports = {
    solidity: "0.8.20",
    networks: {
      vsc: {
        url: "<https://rpc.vscblockchain.org>",
        accounts: [process.env.PRIVATE_KEY],
        chainId: 420042,
      },
    },
    etherscan: {
      apiKey: {
        vsc: "YOUR_VSC_EXPLORER_API_KEY" // if supported
      }
    }
  };
  
  

• Foundry Verification Command (if supported):

  forge verify-contract <DEPLOYED_ADDRESS> \
    src/MyContract.sol:MyContract \
    --chain-id 420042 \
    --etherscan-api-key YOUR_VSC_EXPLORER_API_KEY
  
  

Once verified, your contract will be fully transparent, auditable, and interactable through the VSC Explorer — a best practice for any production deployment.
