“Today, we’re excited to announce the testnet launch of Base, an Ethereum layer 2 (L2) network offering a secure, low-cost, developer-friendly way for anyone, anywhere, to build decentralized apps or “dapps” onchain,” Will Robinson, vice president of engineering at Coinbase, told CoinDesk.“We’re incubating Base inside of Coinbase, leveraging the last decade of our experience building crypto products, and plan to progressively decentralize the chain over time,” Robinson added.
