Ethereum is a decentralized Layer-1 blockchain that enables developers to build and deploy smart contracts and decentralized applications (dApps) using the Ethereum Virtual Machine (EVM). As the foundational environment for EVM-compatible chains, Ethereum has become a standard for smart contract execution across a wide range of blockchain ecosystems. The native token on Ethereum is ETH. Block explorer: https://etherscan.io/
