# Deploy and verify a contract

{% hint style="info" %}
**Prerequisites**

1. This documentation assumes you have already installed MetaMask on your system. If not, please [install MetaMask](/learn/about-wallets/how-to-use-metamask/install-metamask.md) first, either the web-based extension or the mobile app.
2. For your convenience, pin 📍 the MetaMask extension to your preferred browser.

Building a smart contract is an essential part of the creative project that leads to a dApp for Chiliz Chain — or any blockchain, really.

There are two steps that you **must** go through once you have built your dApp's smart contract:

1. Deploying the contract on Chiliz Chain.
2. Verifying that contract.

These two steps are documented here.

{% hint style="success" %}
To ensure that your transaction doesn't remain in "pending" status for too long, you should include enough to cover the fees:

* Minimum gas fee: 2,500 gwei.
* Minimum priority fee: 1 gwei.
  {% endhint %}

## Step 1: Deploy your smart contract

You can use either of these options:

{% content-ref url="/pages/cwZqLlr1ee8FwupJJUCc" %}
[Deploy with Remix](/develop/basics/deploy-a-smart-contract/deploy-with-remix.md)
{% endcontent-ref %}

{% content-ref url="/pages/RFojVMHPNEiBunOWwzIL" %}
[Deploy with thirdweb](/develop/basics/deploy-a-smart-contract/deploy-with-thirdweb.md)
{% endcontent-ref %}

## Step 2: Verify your 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 possible.
{% endhint %}

Here are guides for each:

{% content-ref url="/pages/QmhlZEvcZGdhu1QvIR0p" %}
[Verify with Chiliscan](/develop/basics/verifiy-a-smart-contract/verify-with-chiliscan.md)
{% endcontent-ref %}

{% content-ref url="/pages/uYTtcHioYwh7WkNtwSzW" %}
[Verify with Chiliz Block Explorer](/develop/basics/verifiy-a-smart-contract/verify-with-chiliz-block-explorer.md)
{% endcontent-ref %}

Once your contract is verified, it will receive a "green dot" on the block explorer interface, indicating that your contract can be trusted.

See for instance the PSG Fan Token contract:

{% embed url="<https://chiliscan.com/token/0xc2661815C69c2B3924D3dd0c2C1358A1E38A3105/contract/code>" %}
PSG Fan Token on Chiliscan
{% endembed %}

{% embed url="<https://scan.chiliz.com/address/0xc2661815C69c2B3924D3dd0c2C1358A1E38A3105/contracts#address-tabs>" %}
PSG Fan Token on Chiliz Block Explorer
{% endembed %}
