# 4. Bridge (Optional)

{% hint style="info" %} <mark style="color:blue;">**Intermezzo:**</mark> **help, I think I have to bridge!**

No worries, this can be quite cheap if you know how to do this the most cost-efficient way. To minimize the extra costs for bridging one could choose to first deposit ETH on a network that is already known to have low fees. These are almost always Layer 2 protocols.

Just to name a few that are compatible with the (third-party) bridge discussed below: **Optimism**, **Arbitrum (One)**, **Arbitrum Nova** and **Polygon**. There are more options to choose from, as long as you try to **avoid Ethereum (mainnet)** as this will probably be the most expensive route to take.
{% endhint %}

## Choosing your bridge

If your funds are in your personal wallet but not yet on **zkSync Era,** then they have to be bridged over. For this we suggest **using a third-party bridge**. They are generally *cheaper*, *quicker* and have *more networks* to choose from.

There are a couple bridges that are compatible with **zkSync Era**. We suggest using [**Orbiter Finance**](https://www.orbiter.finance), but feel free to check out other third-party bridges in [zkSync's ecosystem](https://ecosystem.zksync.io).

{% hint style="info" %}
**Deposit with Orbiter Finance**

1. Head over to: <https://www.orbiter.finance/?dest=zkSync%20Era&token=ETH>
2. Connect your wallet.
3. Make sure to select the correct networks (the link should automatically select **zkSync Era** as the *destination*).
4. Enter the *amount* you'd like to bridge. Make sure you have enough to also cover for any bridging fees.
5. Click **Send** *(this will not yet initiate the transaction)*.
6. In the next screen you'll see all details pertaining to your upcoming transaction (including the *Withholding Fee* charged). If everything looks okay, click on **Confirm and Send** and **Confirm** the transaction in your wallet to finish your deposit to zkSync Era.
7. It usually **takes around 30 seconds to a minute** to have your funds on the **zkSync Era** network.

We suggested **using a third-party bridge**, but there are some pros to consider to using the official bridge over, in our case specifically, *Orbiter Finance:*

1. The list of tokens you're able to bridge is quite extensive in comparison,
2. You're able to bridge your tokens to a different wallet address and
3. You might feel more at ease using the official bridge rather than a third-party.

{% hint style="info" %}
**Deposit with txSync Bridge**

1. If you prefer to use the official bridge of zkSync, head on over to <https://portal.txsync.io/bridge>.
2. Connect your wallet.
3. Enter the *amount* you'd like to bridge. Make sure you have enough to also cover for any bridging fees.
4. Click **Continue** if you agree with the fee amount and the arrival time *(this will not yet initiate the transaction)*.
5. Click **Add funds to zkSync Era Mainnet** and **Confirm** the transaction in your wallet to finish your deposit to zkSync Era.
6. Normally it **takes around 15 minutes** to have your funds in your account on the **zkSync Era** network.
