# How to Use $USDC in Quest?

If you want to use tokens outside of the AO ecosystem (such as USDC) to publish public bounty quests, here is the tutorial you’re looking for. First, make sure you have a balance of USDC tokens on the ETH mainnet in your Metamask.

Then, open the AOX website <https://aox.arweave.dev/#/>, click on the Bridge button, connect your Metamask wallet, and sign in to access the cross-chain page.

1. **Select the Source Chain**: Choose the ETH network.                  &#x20;
2. **Select the Token**: Choose USDC as the token.
3. **Select the Target Chain**: Choose the AO network.
4. **Select the Token** : Again, choose USDC as the token.

6. **Confirm the Transaction**: Click confirm. The cross-chain transfer may take some time, so please be patient.

Once this step is completed, you will need to perform one last action to finalize the cross-chain process. Click on the "Transfer" button on this page to send all the tokens you just successfully traded to your **ArConnect** wallet. So please fill ou the block after To with your ArConnect  wallet address. After that, click confirm, and you will see the tokens in your ArConnect.

If you don’t see them, please add the token using its process id to ArConnect.&#x20;
