# The Polygon Network

The [Polygon network](https://polygonscan.com/) is a layer-2 Ethereum sidechain. As the Ethereum blockchain becomes more popular, it becomes more congested and expensive. The Polygon network, as a secondary scaling solution, enables cheaper and faster usage. For GG DAO, it allows you to use the same wallet address as you normally would on Ethereum. It also allows us to provide more diverse functionality to your tokens as well as avoid excessive network transaction fees. Not only does this save you money, but also provides a smoother user experience. The polygon network is environmentally friendly as all Polygon network processes are [certified carbon neutral](https://blog.polygon.technology/polygon-the-eco-friendly-blockchain-scaling-ethereum-bbdd52201ad/).

GG DAO NFTs are built on the Polygon network. Therefore, you will need [$wETH](https://polygonscan.com/token/0x7ceb23fd6bc0add59e62ac25578270cff1b9f619) or [$GG](https://polygonscan.com/) on the Polygon network to purchase them.
