# Bridge ETH/USDC to Optimism

***

1. We recommend Brid.gg for ease of use: [Brid.gg](https://www.brid.gg/op-mainnet?amount=\&originChainId=1\&token=ETH)

2. Click **Connect Wallet**
3. Select the **From** network, this should be whatever network your funds are currently on
   * By default, the link above is configured to bridge ETH from the Ethereum Network to the Optimism Network (OP Mainnet)
4. Select **OP Mainnet** as your **To** network
5. Input $125-135 USD worth of ETH per .box domain you're planning on purchasing
   * We recommend bridging an extra $5-15 USD worth of ETH in order to cover gas fees incurred when purchasing and configuring your .box domain
6. Do not edit the **To address** unless you want the bridged funds to end up in a different wallet
7. Click **Review Transaction**, accept the terms and conditions, click **Confirm**, and finalize the bridging transaction in your wallet
8. You can now proceed to [Purchase a .box Domain](/docs/get-a-.box/purchase-a-.box-domain.md)

{% hint style="warning" %}
Bridging USDC will lead you to hold the wrong token (USDC.E) so we recommend bridging Ethereum to purchase a .box domain
{% endhint %}

{% hint style="info" %}
Gas fees can be high when using Brid.gg. Try the [Across](https://across.to/bridge) Bridge for cheaper gas fees. **When using Across, be sure to change the “To” chain from Arbitrum to Optimism.**
