Can I Add Polygon Mumbai to MetaMask?

Absolutely, Polygon Mumbai is built to be fully compatible with Ethereum's Solidity coding language, making it a breeze to connect with MetaMask. This is because Mumbai is based on the Ethereum network. This feature allows users to interact seamlessly with decentralised applications on the Polygon Mumbai network via their MetaMask wallets.

How to Add Polygon Mumbai to MetaMask

To incorporate Polygon Mumbai into your MetaMask wallet, ChainList is the most reliable option. ChainList is a blockchain aggregator that provides accurate and verified information, such as  RPC settings and Chain ID, on various EVM-compatible networks, including Polygon Mumbai. Once you have added the chain to your MetaMask, you can easily interact with DApps on the network.

Begin using the Polygon Mumbai network by following this easy guide:

  1. Visit the ChainList website and connect it with your MetaMask wallet.
  2. Make sure to check the box that reads 'Include Test Networks'.
  3. In the 'Search Networks' bar, input "Polygon Mumbai".
  4. Locate the specific Polygon Mumbai network you're interested in, and click 'Add to MetaMask'. Your wallet will now effortlessly incorporate the new network.

What is Polygon Mumbai?‍

Mumbai is Polygon's testnet, serving as a layer-two scaling solution for Ethereum. Designed to facilitate risk-free testing for developers, Mumbai replicates the features and functionalities of Polygon's mainnet. It uses a proof-of-stake (PoS) consensus mechanism and offers high throughput and low transaction fees, leveraging Ethereum's robust security architecture. 

Developers can use Mumbai to deploy, test, and execute decentralised applications (dApps) without incurring any costs. The testnet uses its own version of MATIC tokens, which hold no real-world value, allowing developers to test their projects extensively. Mumbai is particularly beneficial for those looking to migrate Ethereum-compatible dApps to Polygon, as it provides a seamless testing environment.


To summarise, Polygon Mumbai Testnet is a powerful and cost-effective layer-two solution that enhances the Ethereum network's capabilities and offers seamless integration with MetaMask wallets. This makes it easier for users to engage with decentralised applications on the Polygon Mumbai network. ChainList is a reliable resource for adding the Mumbai network to your MetaMask, ensuring you have all the verified information you need to get started.
