$ETH

ETH refers to *Ethereum*, the second-largest cryptocurrency by market capitalization after Bitcoin (BTC). Ethereum is a decentralized, open-source blockchain that enables developers to build and deploy smart contracts and decentralized applications (dApps).

Ethereum's native cryptocurrency is *Ether (ETH)*, which is used to pay for transaction fees and computational services on the Ethereum network.

Ethereum has gained significant attention due to its ability to support decentralized finance (DeFi), NFTs (non-fungible tokens), and many other innovations in the blockchain space. The platform is undergoing a major upgrade known as *Ethereum 2.0* to improve scalability, security, and sustainability, moving from proof-of-work (PoW) to proof-of-stake (PoS) consensus mechanism.

The value of $ETH fluctuates based on market trends, network adoption, and technological advancements within the Ethereum ecosystem.
