What is the Polygon ecosystem?

Polygon, formerly known as the Matic Network, was founded in 2017. Polygon is a layer-2 scaling solution that runs alongside the Ethereum blockchain.

Polygon (MATIC) is Polygon’s primary cryptocurrency, which is used to pay for transaction fees, also known as gas. You can also stake MATIC. MATIC has a limited supply, with about 7.4 billion in circulation. There will never be more than 10 billion coins in circulation.

The Polygon ecosystem is comprised of Polygon tokens, NFTs, DEXs, DeFi dApps, and every other type of Web3 app you can think of.

If you’re looking for blockchain data, the most popular block explorer for Polygon is PolygonScan 

What are some popular dApps and Web3 apps on Ethereum?

There are a lot of dApps and Web3 apps to explore, that cover everything from DeFi to staking to NFTs and more. Below, you can find some of the most popular Ethereum Web3 apps.

You can connect and explore without any funds in your wallet. But if you want to interact with Web3 apps, you’ll need some Polygon (MATIC) in your wallet to pay transaction fees, also known as gas.
