Polygon is one of the leading scaling solutions for Ethereum. For those who have experienced trading with Uniswap and had to deal with high gas fees, with the Polygon network you won’t have to. Not only are transaction fees cheaper, transaction speeds are super fast.
Mass adoption for Polygon continues as newer crypto projects join the network. You have DeFi protocols such as Sushiswap, Aave, and Curve all compatible with Polygon. As of now, Ethereum and Binance Smart Chain (BSC) continue to dominate the DeFi exchange space. On the other hand, Polygon continues to carve out a bigger piece for itself.
In this guide we will show you how to add Polygon to your Metamask Wallet. This will allow you to use platforms such as Sushiswap, Atari, Polymarket, Decentraland (MANA), and more.
