# How to verify a smart contract?

          In the next part of this tutorial, we’ll guide you through the process of verifying your own smart contract on the ICB Mainnet and ICB Testnet.

          **ICB Mainnet verification:**\
          Contract address: `0x6171cB11F6137c47730415e806D61C101883f16A`

          **Steps to verify:**

1. Go to the deployed contract address on [icbscan.io](https://icbscan.io).
2. Search for the contract address.
3. Press the **Contract** tab, then click **Verify & Publish**.
4. Select the contract license.
5. Select the verification model or compiler type.
6. Select the compiler version.
7. Select the EVM version.
8. Enable or disable **“Optimization enable”**. If enabled, provide the number of runs.
9. Add the contract source code.
10. Press **Verify & Publish** after checking all the information.

          In our case will be:

&#x20;         You can start interacting with the contract directly from ICBScan. To do this, go to the **Read / Write Contract** tab.
