Contract Verification

Guidelines for verifying smart contracts on MetaChain using the Metascan Explorer.

Verifying your smart contract allows others to see the source code of your deployed contract, ensuring transparency and trustworthiness.

Identify Compiler Version

Ensure you know the exact Solidity compiler version used. This can be found in your contract or Truffle configuration.

// truffle-config.js
compilers: {
    solc: {
      version: "0.8.0",  // Example version
    }
}

Verification

This step-by-step guide will walk you through the process of verifying your contract on MetaChain.

Step 1: Navigate to MetaChain's Verification Portal

Go to the MetaChain's contract verification portal (replace with the actual URL once known).

Step 2: Input Contract Details

• Contract Address: The address where your contract is deployed.

• Contract Name: The name of your main contract (e.g., MyContract).

• Compiler Version: The version you identified in Step 3.

• Optimization: Whether you used optimization during compilation.

• Source Code: Paste your contract's source code (or the flattened version from Step 2).

Step 3: Verify

Click on the "Verify" button. If all details are correct, you should see a success message indicating that your contract is now verified.

Tip: Always double-check the details before verification to avoid errors.

Tip: If verification fails, ensure that the source code and compiler version match exactly with what was used during deployment.
