How to add Polygon to MetaMask

MetaMask supports the Polygon network because it is an Ethereum Virtual Machine (EVM) compatible network. This means that the Polygon blockchain is written in the same programming language as Ethereum, called 'Solidity'. The entire process of adding the Matic Mainnet to MetaMask only takes a minute.

Follow this easy guide to add the Polygon network to your Metamask account:

  1. Open your MetaMask, click ‘Networks’ and tap ‘Add a Network’.
  2. Add the verified Polygon RPC details into the MetaMask form and tap ‘Add Network’.
  3. Interact with your favourite DApps to start using the Matic Mainnet.

About Polygon

Polygon is a Layer 2 scaling solution enabling fast and inexpensive Ethereum transactions. It does this by using Plasma chains and sidechains that run parallel to the main Ethereum blockchain. This makes it possible to process transactions off-chain, which greatly reduces congestion on the Ethereum network. The blockchain is powered by the MATIC token, which is used to pay transaction fees on the network.

MATIC was founded in 2017 by three Indian developers: Jaynti Kanani, Anurag Arjun, and Sandeep Nailwal. Initially known as Matic Network, the project was rebranded to Polygon in 2021. It has been audited by several independent security firms and is backed by a number of large corporations, including Samsung and Microsoft.


To sum up, adding the Polygon network to a MetaMask wallet is a simple task that only takes a minute to complete. Once you have added the Matic Mainnet to your wallet, you can freely access all the applications and platforms on the Polygon network.
