# 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](https://docs.nfd.gg/main/eng-combine-software/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 have several bridges to choose from: official bridges and third-party bridges;
* 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 through official bridges, you must have ETH on your balance in the Ethereum network;
* In the **Account Delays** section, set the delay between wallet launches in seconds;
* Clicking on **Pro** will open the **Gas guard** setting. If this delay is activated, your wallet will additionally go to sleep if several accounts in the same session are simultaneously ready to work after reaching the gas level you set for the software. We did this so that all these wallets do not start sending transactions simultaneously after reaching the gas level you set. The standard delay is set in the range of 30 to 150 seconds;
* In the **Chain from and to** fields, select 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;
* 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 use an official bridge: **All**, **Send range**, and **Leave range**, and two functions, **Send range** and **Leave range**, when using a third-party bridge:
  1. **All** - will transfer all available tokens on the wallet to the destination network;
  2. **Send range** - will allow you to send tokens within the specified range;
  3. **Leave range** - will allow you to leave a specified range of tokens on the wallets and send only what is above this range.
* Enter the amount range in the required fields and click **Apply to selected wallets**. The amount for each wallet will be generated randomly within the specified range. The amount that will be 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 in the Ethereum network at which transactions will be made. The software will wait for the gas to drop to the desired level and start making transactions when the gas drops to the value you specified. After launching the session, it is possible to change the upper Gwei limit in the **Logs & Progress** tab by going to the **Sessions** subsection;
* To make wallets start working in random order, leave the **Randomize wallets** checkbox enabled;
* To launch 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/layer-zero-module/logs-and-progress).
