# How to Use the Test Environment

The Lagrange testing environment is a testnet connected to the Swan Proxima Chain, designed for users and partners to try out features and transactions. To get started, visit <https://testnet.lagrange.computer>.

You'll need [SwanETH](#step-2-bridge-eth-from-sepolia-to-swan-proxima) for gas fees, which you can obtain by swapping [Sepolia ETH](#step-1-fund-your-wallet-with-sepolia-eth-tokens) via a [bridge](https://bridge.swanchain.io/). Additionally, you'll need [tSWAN ](#step3-claim-testswan)to pay Computing Providers for the resources required to power your Space (Application).&#x20;

Follow the steps outlined below to begin using the test environment.

### 1.Set Up MetaMask

**Step 1: Add Swan Chain Proxima Testnet to MetaMask**

Swan, built at OP Stack, is currently available on the **Sepolia Testnet**. To engage with Swan, you'll need **Sepolia Testnet ETH**. Therefore, before adding Swan Testnet into MetaMask, it's essential to add the Sepolia Testnet to your wallet as well.

1\. Open MetaMask and click on the network name at the top ( "Ethereum Mainnet").

2\. Toggle **Show test networks** to reveal testnets.
