Base is an Ethereum Layer 2 network built by Coinbase.
Base serves as both a home for Coinbase’s onchain products and an open ecosystem where anyone can build.
Base uses ETH as payment for network costs. You can explore transactions done on the Base network using https://basescan.org/
The Uniswap web app supports the Base Network. This means anyone can swap and provide liquidity using the Uniswap Protocol on the Base Network.
