# Check ERC-20 Token

You can add and verify the custom token in MetaMask for ERC-20 tokens distributed using Remix.

ERC-20 contracts must be deployed in advance. Please refer to [Write ERC-20 Contract ](/en/tutorial/erc-20-token/write-erc-20-contract.md)for ERC-20 Contract deployment. 

We will proceed with the process of checking the ERC-20 token in the order below\..

* Step 1 :  Access MetaMask
* Step 2 : Check Token Contract Address
* Step 3 : Add Custom Token
* Step 4 : Confirm Custom Token

{% hint style="info" %}
All examples are based on WEMIX3.0 Testnet.
{% endhint %}

## Step 1 : Access MetaMask

You must run the MetaMask Extensions that are installed. If you do not have MetaMask Extensions installed, you must go to the [Chrome Web Store](https://chrome.google.com/webstore/category/extensions) to download and run MetaMask.

Once MetaMask is running, you can now change the network from Ethereum to WEMIX3.0 Testnet as shown in the picture below.

## Step 2 : Check Token Contract Address

A token contract address is required to add as a Custom Token. \
The ERC-20 Contract Address deployed through Remix can be found in [Testnet Explorer](https://explorer.test.wemix.com/).

After accessing [Testnet Explorer](https://explorer.test.wemix.com/), you can check tokens by selecting 'Token > Tokens List'.

Find the name of the token entered when creating the ERC-20 contract, check the Contract Address, and copy it.

## Step 3 : Add Custom Token

Return to the MetaMask and select 'Import tokens' and enter 'Token contract address'. \
When entering 'Token contract address', Token symbol and Token decision are automatically entered.

If you select 'Add custom token' in the picture above, a screen will be displayed to confirm whether you want to add the token finally. Select 'Import tokens' to complete token registration.

## Step 4 : Confirm Custom Token

Once the token registration is complete, you can check the ERC-20 Token deployed at the bottom of TWEMIX as shown below.&#x20;

Below is an additional example of Token with Token Name 'WT Token'.
