Step-by-step guide for verifying smart contracts on the Filecoin network using the Filfox explorer's web interface.

Contract Verification with Filfox

The following guide walks you through the process of contract verification using the Filfox Contract Verification page.

Prerequisites

  • A deployed smart contract on Filecoin
  • Your contract's source code (.sol file)
  • Remix IDE for flattening contracts
  • Contract deployment details (address, compiler version, license)

Step-by-Step Verification Process

Step 1: Prepare Your Contract Source Code

  1. Open Remix IDE:

  1. Flatten your contract:

    • In the File Explorer sidebar, under contracts, right-click on your contract
    • Select Flatten from the menu
    • This creates a <contract-name>_flattened.sol file with all dependencies included

  2. Verify contract details:

    • Ensure the license and Solidity version match your original contract
    • Click Save to save the flattened contract

  3. Download the flattened contract:

    • Right-click on <contract-name>_flattened.sol
    • Select Download to save the file locally

  4. Gather required information:

    • Contract deployment address
    • Contract license type (if any)
    • Solidity compiler version used for deployment

Step 2: Submit for Verification

  1. Access Filfox verification page:
  2. Fill in contract information:
    • Enter your contract's deployment address
    • Select the appropriate license type
    • Choose the compiler version used for deployment

  1. Upload source code:
    • Click Continue to proceed
    • Click Select .sol files
    • Choose your flattened .sol file
    • Click Verify and Publish to submit

Step 3: Verification Complete

Once submitted, Filfox will process your verification request. Upon successful verification, you'll see a success message confirming your contract is now verified.

Viewing Your Verified Contract

  1. Navigate to your contract:
    • Enter your contract address in the Filfox search bar
    • This will take you to your contract's page

  1. View verification status:

    • Scroll down and select the Contract tab
    • Look for the Contract Source Code Verified banner
    • Your contract's source code and ABI will now be publicly visible

  2. Explore verified contracts:
