# Ontology Bridge Transfer

With the exciting launch of the Ontology EVM, we are pleased to provide the guide for bridging tokens from OEP-4 tokens to ORC-20 tokens. Doing so is necessary to participate in EVM applications. Currently, you are able to transfer ONG or bridge your WING, ONT, pETH, pWBTC, pUSDT, and pUSDC  tokens from Ontology to Ontology EVM.

Open the[ **Ontology Bridge website**](https://bridge.ont.io/) and click “Connect Wallet” in the upper right corner.

{% hint style="info" %}
Note: To bridge an ORC-20 token for a native token, click the double arrow between “From” and “To” so that “ORC-20” is under “From” and “Native” is under “To”. This requires the Approve operation first. After the Approve is successful, the process is the same as the Native token exchange for the ORC-20 token as described above.
{% endhint %}
