How to Add Polygon (MATIC) Network to MetaMask

Polygon (MATIC) is a versatile, scalable, and efficient multi-chain system that enhances Ethereum's capabilities. Discover the easy steps to integrate Polygon with your MetaMask wallet for a broader crypto experience.

Polygon, initially known as Matic Network, provides a scalable solution alongside the Ethereum blockchain. It stands out as a game-changer layer-2 project in the Ethereum ecosystem. Its interoperability with the Ethereum network facilitates a seamless transfer of assets and data between the two networks, making it easier for developers to port their projects and for users to access a broad range of dApps and services.

With a modified Proof of Stake (PoS) consensus mechanism, Polygon offers efficient transaction processing. The network's high transaction volume capacity, user-friendly interface, and robust security make it an appealing ecosystem for various crypto activities.

MetaMask, a self-custodial web wallet, is a popular choice among over 100 million users for its compatibility with Ethereum and other Ethereum Virtual Machine (EVM)-compatible blockchains. As a gateway to decentralized applications (dApps), web3 users need to know how to add the Polygon mainnet to their MetaMask wallets.

This guide will walk you through the process of integrating the Polygon network with your MetaMask wallet, a crucial step for those eager to delve into the depths of Web3 and DeFi spaces.

The Polygon ecosystem has experienced significant advancements in 2023, marking a year of substantial growth and innovation. Here are some key developments:

Web3 Gaming and NFT Initiatives: Polygon has been actively involved in the web3 gaming sector, leading in hosting the most Web3 games compared to other blockchain ecosystems. This is partly due to its collaboration with Immutable, a web3 gaming platform, and its partnership with Ubisoft to create new gaming experiences. Additionally, OpenSea, a major NFT marketplace, expanded its operations to include Polygon, enhancing the NFT ecosystem on the platform.
Immutable zkEVM Testnet Launch: The Polygon zkEVM chain, launched in March 2023, reached significant milestones in terms of transactions and bridge volume. This technology aims to improve scalability and efficiency within the ecosystem. Another notable advancement is the introduction of a new feature by Coinbase, allowing Polygon users to pay gas fees with the token they are swapping, and the implementation of a gasless mode for failed transactions.
Record-Breaking Transactions and User Growth: The Polygon PoS chain hit new highs in daily transactions in November 2023, reaching 16.4 million in a single day. This reflects the rapid growth of the ecosystem, with the number of unique addresses surpassing 385 million.
Polygon 2.0 and Transition to POL Token: With the Polygon 2.0 upgrade, Polygon is transitioning into a supernet of ZK networks, aiming for interoperability and near-instant finality on the Ethereum network. A significant aspect of this upgrade is the transition from MATIC to POL token, intended to enhance the network's functionality and enable holders to become validators.
Partnerships and Corporate Interest: The network has formed strategic partnerships with major companies like Starbucks and QuickNode. These collaborations aim to explore blockchain applications in various sectors, from the coffee supply chain to decentralized finance (DeFi) and lending platforms.
NFT and Social Media Integration: Polygon's integration with social media platforms, particularly Instagram's upcoming NFT trading platform, highlights its expanding role in the digital art and collectibles space. This integration is expected further to increase the utility and adoption of the Polygon network.

Overall, these developments indicate a strong and diverse growth trajectory for Polygon in 2023, with a focus on expanding its technology, user base, and applications across various sectors.

MetaMask doesn’t have Polygon added as a network by default, but you can add the Polygon network and explore its ecosystem in a few simple steps. Before you begin, ensure a MetaMask wallet is installed and configured on your device.

Go to the official MetaMask website, select the version suitable for your device (browser extension or mobile app), and follow the instructions to download and install. Open MetaMask and choose to either 'Create a New Wallet' (for new users) or 'Import Wallet' (for existing users). New users will need to create a password and store their recovery phrase safely.
