Base Blockchain is an Ethereum-based Layer-2 network developed by Coinbase as a solution to improve the scalability and efficiency of the Ethereum main network. Base Blockchain is designed to provide a more efficient blockchain infrastructure with wider scalability.

Base Blockchain is directly supported by the Coinbase development team, allowing developers to leverage their pre-existing products, user base, and tools. The main advantage of Base Blockchain is its broader scalability compared to Ethereum, with faster and more cost-efficient transactions. Each transaction on Base's second layer is said to be ten times more efficient than transactions on Ethereum's primary layer.
