Ethereum (ETH) is a blockchain platform built for more than simple payments. It lets developers run smart contracts, which are programs that execute on the blockchain.
What ETH is used for
ETH is the native asset of Ethereum. It is used to pay network fees, secure the network through staking, and interact with decentralized applications.
Why Ethereum is important
Many crypto ideas became practical on Ethereum, including DeFi, NFTs, DAOs, and token launches. Instead of only moving money, Ethereum allows software logic to run without one company controlling the whole system.
Ethereum is powerful, but users still need to understand gas fees, wallets, and scams. A transaction sent to the wrong address or signed carelessly can be difficult or impossible to reverse.
