Summary: The Polygon Mumbai testnet is an Ethereum Virtual Machine (EVM) compatible environment that replicates Polygon mainnet and allows users to develop, test and deploy their applications. The easiest way to add Polygon Mumbai to MetaMask is by adding the verified network information and RPC endpoints to you your wallet.
We recommend doing this via ChainList, which is the largest EVM network information aggregator that allows you to join Polygon Mumbai at the click of a button. You can continue reading below for a step-by-step guide on how to get started.

How to Add Polygon Mumbai Testnet to MetaMask
Adding the Polygon testnet into your MetaMask wallet can differ slightly depending on the specific testnet you wish to access (e.g Mumbai, Goerli or Avail Testnet). However, ChainList streamlines the process for connecting to any Polygon testnet (as well as other networks) by compiling Chain ID and Network ID data, enabling users to establish connections with ease.
Follow this straightforward guide to begin:
- Navigate to ChainList and link your MetaMask Wallet.
- Tick the 'Include Testnets' option.
- Input 'Polygon' into the search bar and locate the desired testnet (Polygon Mumbai).
- Click 'Add to MetaMask', and the network will be integrated into your wallet.
What is Polygon Mumbai?
Mumbai is the testnet for the Polygon network (previously known as Matic). Polygon is a layer 2 scaling solution for Ethereum that aims to provide faster and cheaper transactions using its Proof of Stake (PoS) sidechain. Developers can use the Mumbai testnet to deploy and test their decentralized applications (dApps) and smart contracts before launching them on the Polygon mainnet.
What can I do on Polygon Mumbai?
On Polygon Mumbai, you can experiment with dApps and smart contracts in a risk-free environment before deploying them on the mainnet. Testnet tokens play a crucial role, as they simulate the mainnet tokens without holding any real value. They enable developers and users to test transactions, staking, token swaps, and other features without incurring actual costs, ensuring a reliable and secure transition to the mainnet.
Bottom Line
In conclusion, the Polygon Mumbai testnet offers a secure and efficient environment for developers and users to build, test, and deploy their dApps and smart contracts without risking real assets. By adding the Polygon Mumbai testnet to your MetaMask wallet through ChainList, you can easily access its functionalities and leverage testnet tokens for a seamless transition to the mainnet. This step-by-step guide simplifies the process of integrating Polygon Mumbai, allowing you to focus on innovating and enhancing your projects in the ever-evolving blockchain ecosystem.
