### Add Sepolia USDC to MetaMask

Navigate to the [USDC Contract on Sepolia](https://sepolia.etherscan.io/address/0x1c7D4B196Cb0C7B01d743Fbc6116a902379C7238) and copy the address (it is also listed below);

{% code title="USDC address on Sepolia" %}

```solidity
0x1c7D4B196Cb0C7B01d743Fbc6116a902379C7238
```

{% endcode %}

You have done this dance before, but let's do it again. In MetaMask, under the "Tokens" tab, click "+ Import tokens":

<div align="left"><figure><img src="/files/8UQJ9rmyLXEgx4b18eML" alt=""><figcaption><p>Click "+ Import tokens"</p></figcaption></figure></div>

Paste in the USDC contract address on Sepolia and click "Next":

<div align="left"><figure><img src="/files/MW5jrF5fGJ5sQssm1HHA" alt=""><figcaption><p>Importing Sepolia USDC token</p></figcaption></figure></div>

On the next window, you will see the USDC token and it already has a `0.1` balance for you account! That was from our CCIP transaction previously. Pretty cool! Click the "import" button at the bottom:

<div align="left"><figure><img src="/files/hlOegl8VyB8sk5cJdHFX" alt=""><figcaption><p>Importing the Sepolia USDC token</p></figcaption></figure></div>

Back at the "Tokens" tab you will now see your USDC token and balance:

<div align="left"><figure><img src="/files/YCpGWQZBrBvUsQDMbHte" alt=""><figcaption></figcaption></figure></div>

### USDC on Sepolia Etherscan

Click on the 1. “TOKEN HOLDINGS '' pull-down menu and then 2. Click on the USDC token:

<div align="left"><figure><img src="/files/sS9eMYhpNMvYdMGlyAEP" alt=""><figcaption><p>Click the USDC token in your TOKEN HOLDINGS</p></figcaption></figure></div>

On the next page, you will see CCIP transaction you just performed:

<figure><img src="/files/3pdnjzlHoqG6eqdNUGm8" alt=""><figcaption></figcaption></figure>

Again, congratulate yourself!  You sent USDC from Avalanche Fuji Testnet to Ethereum Sepolia using CCIP!
