Base, a new platform built on Ethereum, is gaining attention for its easy access to ETH through Coinbase and Coinbase Wallet. With a potential user base of over 100 million Coinbase users, Base is seen as a significant growth opportunity in the DeFi space. Users can directly buy Base coins on Coinbase, and the platform is expected to onboard all Coinbase customers, leveraging the massive user base of over 90 million registered users. Base operates as a custodial solution, allowing users to easily convert mainnet ETH to Base ETH without bridge fees or waiting time.
