$ETH Ethereum (ETH) is more than a cryptocurrency—it's a foundational platform for decentralized innovation. Built to be programmable, Ethereum allows developers to create smart contracts and decentralized applications (dApps) that operate without downtime, fraud, or third-party interference. This flexibility has fueled the rise of entire sectors like decentralized finance (DeFi), where users can lend, borrow, and trade without banks, and non-fungible tokens (NFTs), which have transformed digital ownership. Ethereum is continuously evolving, with upgrades like sharding planned to improve scalability. As the second-largest blockchain by market cap, Ethereum remains a driving force behind the growing ecosystem of decentralized technologies and Web3.
