How to Connect Polygon to MetaMask

Polygon is an Ethereum-based Layer 2 scaling solution. That means Polygon runs a souped up version of Ethereum that is faster and cheaper than the original network. Polygon helps Ethereum handle more transactions by processing them on various new ‘side chains’.

This frees up some space on the Ethereum blockchain and is similar to multi-chain projects like Polkadot and Cosmos. All of the transactions on Polygon are bundled together, checked for validity, and then written to the Ethereum mainnet, which also provides Polygon with robust security and “blockchain integrity”.

MetaMask supports Ethereum and any other token developed on the Ethereum Blockchain (ERC20 tokens), such as Tether, USDC, DAI, and the Uniswap token. It is also possible to add specific tokens or Blockchains, even if they aren’t officially supported or immediately compatible. Read more about MetaMask here.
