# Before You Get Started

Swan Testnet provides support for both the **Polygon Mumbai Testnet** and **Swan Testnet** (Built on OP Stack), offering the flexibility to pay for building Spaces, regardless of your MetaMask connection to both chains.

Here's what you'll need:

**Gas Fees:** Gas Fee is a type of transaction fee that you have to pay to execute a transaction. The fees vary based on the blockchain. For instance, transactions on **Polygon Mumbai** require **MATIC**, while **Swan Testnet** transactions require **Swan-ETH**.

**Payment to Computing Providers:** In addition to gas fees, you'll need to pay Computing Providers in **USDC** to exchange their computing resources for powering your Space (Application).

Before immersing yourself in the Swan Jupiter Testnet Campaign, ensure you make the necessary preparations:

**For Polygon Mumbai Connection:**

1. [Add Mumbai Testnet to MetaMask.](#step-1-add-mumbai-testnet-to-metamask)
2. [Fund your wallet with MATIC and USDC](#step2-fund-your-wallet-with-test-matic-tokens).

**For Swan Testnet Connection:**

1. [Add Swan Testnet/ETH Goerli to MetaMask](#step-1-add-swan-testnet-to-metamask).
2. [Fund your wallet with SWAN-ETH and USDC](#step-3-fund-your-wallet-with-test-tokens).
