BASE is a Layer 2 (L2) blockchain built on Ethereum by the company called Coinbase. It’s designed to make using Ethereum faster and cheaper.
Since Ethereum can be slow and expensive, BASE helps by reducing gas fees (the small cost you pay for transactions) while ensuring the security and reliability of your transactions.
To pay for gas fees on BASE (the fees you pay to the blockchain to execute the transaction), you’ll need ETH on Base (not regular Ethereum ETH).
