Etherscan stands at the forefront as the premier block explorer and a comprehensive platform for Ethereum, encompassing search functionalities, APIs, and analytics. Established and introduced in 2015, Etherscan represents one of the pioneering and enduring independent initiatives tailored for Ethereum and its user base. Its fundamental goal has been to ensure inclusive accessibility to blockchain data, making it one of the earliest and most enduring projects dedicated to serving the Ethereum community. While not a wallet service, Etherscan helps users track Ethereum network activity. It's a free tool, though having an account offers extra features like address tracking and transaction notifications.

Users can explore assets held in any public Ethereum wallet, check balances, view transaction histories, and assess gas fees. Etherscan also allows for the verification of smart contracts and offers insights into on-chain metrics like gas costs. It's not involved in private transactions and doesn't store keys. Additionally, developers can access its APIs for building decentralized applications. Etherscan proves invaluable for keeping tabs on Ethereum blockchain activity, offering transparency and accessibility to users worldwide. Simply inputting a public Ethereum wallet address into the search field allows users to view associated transactions.
