# Getting Test ETH

This guide provides step-by-step instructions on how to acquire test ETH and bridge it to the Arbitrum Sepolia testnet. Having test ETH is essential for interacting with the Cortensor network in the development and testing phases.

## **Step 1: Acquire Test ETH from a Faucet**

1. **Find a Test ETH Faucet**\
   Access a trusted faucet where you can get test ETH. Examples include:
   * [Sepolia Faucet on Alchemy](https://sepoliafaucet.com)
   * [Sepolia Faucet on Paradigm](https://faucet.paradigm.xyz)
2. **Request Test ETH**\
   Enter your wallet address and complete any CAPTCHA requirements. Click the “Send” or “Request” button to receive test ETH in your wallet.

## **Step 2: Connect to Arbitrum Sepolia Network**

1. **Add Arbitrum Sepolia Network to MetaMask (if not added)**
   * Open MetaMask, go to **Settings > Networks**, and click **Add Network**.
   * Fill in the following details:
     * **Network Name:** Arbitrum Sepolia Testnet
     * **New RPC URL:** `https://sepolia.arbitrum.io/rpc`
     * **Chain ID:** `421613`
     * **Currency Symbol:** ETH
     * **Block Explorer URL:** <https://sepolia-explorer.arbitrum.io/>
2. **Switch to the Arbitrum Sepolia Network**\
   Open MetaMask and select the Arbitrum Sepolia network from the dropdown.

## **Step 3: Bridge ETH to Arbitrum Sepolia**

1. **Access the Arbitrum Bridge**\
   Go to the official Arbitrum Bridge:\
   <https://bridge.arbitrum.io/>
2. **Connect Wallet**\
   Click on **Connect Wallet** and choose MetaMask or your preferred wallet. Ensure that it’s connected to the Sepolia network.
3. **Initiate the Bridge Transfer**
   * In the **From** section, select the Sepolia network and choose ETH.
   * In the **To** section, choose **Arbitrum Sepolia**.
   * Enter the amount of ETH you wish to bridge and confirm the transaction.
4. **Approve and Confirm**\
   After initiating the bridge, you’ll need to approve and confirm the transaction in your wallet. Once confirmed, your test ETH will be available on Arbitrum Sepolia.

## **Additional Notes**

* It may take a few minutes for the transaction to complete and for the test ETH to appear on Arbitrum Sepolia.
* If you encounter any issues, check the transaction status on the Sepolia and Arbitrum explorers linked above.

Once your test ETH is on Arbitrum Sepolia, you’re ready to interact with the Cortensor test environment!
