# Verify a Smart Contract

{% hint style="success" %}
After creating a smart contract, it is **necessary** to verify it. \
Only **you** can do it, and you should do it as soon as the contract is deployed.
{% endhint %}

Verifying a smart contract allows you to confirm that the contract's source code corresponds to a specific contract address on the blockchain. This is crucial for transparency and trust, especially in the decentralized world of blockchain. 

Once you have deployed your smart contract on Chiliz Chain, you can verify it by using a block explorer, such as [Chiliscan](https://chiliscan.com/) (by [Routescan](https://routescan.io/)) or [Chiliz Block Explorer](https://scan.chiliz.com/) (by [Blockscout](https://www.blockscout.com/)).

You can also verify your contract through the command line:

Note that it might be easier for you to validate your deployed smart contract using a flattened version of it. Here is how:

In any case, always follow the best practices!
