Ensure that all detail is correct then click on the **Issue Token** button. <mark style="color:yellow;">**The code here is only displayed in this step**</mark>. Hence It is recommended that you copy & store it to your file. So you can use it to perform the contract verification later on.

**If you didn't copy the source code here, there is no way for you to go back to copy it again**

**Step 2:** Fill in the following information

* **Contract Address**: **Fetched** the contract address **automatically**
* **Contract Name**: If you create a **token** via **Viction Issuer** then the name should be
  * **MyVRC25Mintable** for **Reissueable** token (selected when issuing)
  * **MyVRC25** for **Non-reissueable** token
* **Complier:** Select the compiler version **v0.7.6** for verifying the **contract is issued** from **VicIssuer**
* **Optimization:** Default is **No**. Refer: [![](https://cdn.sstatic.net/Sites/ethereum/Img/favicon.ico?v=40dede55262c)'Runs (Optimizer) ' and 'Optimization' while verifying source code on Etherscan](https://ethereum.stackexchange.com/questions/64172/runs-optimizer-and-optimization-while-verifying-source-code-on-etherscan)
* Click on the “**Add Solidity Source Code**“ to input the source code.

  * **File name** can be any thing without **space** or **special characters**.
  * **Solidity Source Code**: Copy & paste your source code from the VicIssuer screen.&#x20;
