# Bridge mode
Thanks to the Bridge mode, you can replenish wallet balances with native tokens for further activity in the desired network. Bridge mode allows bridging tokens from any available network to another, without being tied to the module's network.
* In the **Mode** section, select **Bridge Mode**;
* In the **Run** mode section, choose how wallets will be launched:
1. **Parallel**: wallets will operate concurrently (multithreaded) with or without proxies;
2. **One-by-one**: wallets will be launched one after another with or without proxies;
3. **One-by-one (mobile proxy)**: wallets will be launched one after another using mobile proxies. Mobile proxies must first be added to the Settings -> [**Proxies**](https://docs.nfd.gg/main/eng-combine-software/section-settings/proxies) section and linked to accounts in the Account Manager.
* To launch a pre-prepared group of wallets, select the desired group in the **Select Accounts group to launch** section;
* In the **Bridge Type** section, select the bridge through which you want to send tokens. All modules offer several bridges to choose from: official bridges and bridges from third-party developers;
* If you want to send funds through an official bridge, select it from the list and proceed to the settings. Almost all official bridges work only with the Ethereum network. Therefore, to send ETH to an L2 network via official bridges, you must have ETH on your Ethereum balance;
* In the **Account Delays** section, set the delay between wallet launches in seconds;
* Clicking **Pro** will open the **Gas guard** setting. If this delay is activated, your wallet will go to sleep if multiple accounts in the same session are ready to work simultaneously after reaching the gas level you set for the software. This is to prevent all these wallets from sending transactions simultaneously after reaching your specified gas level. The standard delay is set between 30 to 150 seconds;
* If you are using an official bridge, select **Deposit** in the **Bridge mode** field if you want to send tokens from the Ethereum network to Linea, or **Withdraw** if you want to send funds from Linea to Ethereum.
* If you are using a bridge from third-party developers or an official bridge that allows selecting networks other than Ethereum, then in the **Chain from and to** field, choose the network from which tokens will be sent in the first window and the network to which tokens will be sent in the second window;
* Below the network selection fields, there are two informational banners: **Min amount**, which displays the minimum sending amount, and **Trading fee**, which shows the bridge's commission excluding gas fees;
* Click **Update Balances** to see the current balance on the wallets;
* Select the wallets you want to use in the session;
* In the **Amount** section, there are three functions if you are using the official bridge and two functions if using a third-party bridge:
1. **All** - transfers all available tokens on the wallet to the destination network;
2. **Send range** - allows you to send tokens within a specified range;
3. **Leave range** - allows you to leave a specified range of tokens on the wallets and send only the amount above this range;
* Enter the amount range in the required fields and click **Apply to selected wallets**. The amount for each wallet will be randomly generated within the specified range. The amount applied to the wallet can be seen in the **Amount to bridge**field. You can also manually change the amount in this field;
* In the **Max gas price** section, set the maximum gas price in the Ethereum network at which transactions will be made. The software will wait for the gas price to drop to the specified level and will start making transactions when the gas price reaches the value you set. After starting the session, you can change the upper Gwei limit in the **Logs & Progress** tab, under the **Sessions** subsection;
* To make the wallets work in random order, keep the **Randomize wallets** checkbox checked;
* To start the wallets, click **Launch**.
* Your wallets have been launched. You can track the process of work of your wallets in the section [Logs & Progress](https://docs.nfd.gg/main/eng-combine-software/modules/operation-and-launching-of-modules/linea-module/logs-and-progress).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://nfd-gg.gitbook.io/main/eng-combine-software/modules/operation-and-launching-of-modules/linea-module/settings-and-launch/bridge-mode.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
