Smart contracts: - Smart contracts are self-executing contracts with terms written directly into the code. Ethereum's platform facilitates the creation and execution of these contracts. 3. Decentralized Applications (DApps): - DApps are applications that run on the Ethereum blockchain, leveraging its decentralized and secure infrastructure. 4. Ether (ETH): - Ether is the native cryptocurrency of the Ethereum platform. It is used to compensate miners for securing the network and to execute smart contracts. 5. ERC-20 tokens: - Many tokens on the Ethereum platform follow the ERC-20 standard, allowing for the creation of various digital assets and tokens. 6. ETH/USD Trading: - ETH/USD is actively traded on several cryptocurrency exchanges. Traders use this pair to speculate on the price movement of Ethereum against the U.S. dollar. 7. Volatility: - Similar to bitcoin, the price of Ethereum is known for its volatility, which is influenced by factors such as market demand, technological developments, regulatory news and broader market trends. 8.

NFTs (Non-Fungible Tokens): - Ethereum is widely used to create and trade NFTs, which represent unique digital or real-world assets such as art, music, and collectibles. 13. Wallets: - Ethereum can be stored in digital wallets, which can be software-based, hardware-based, online or offline. 14. Clearing: - Transactions and smart contract executions on the Ethereum network require gas fees, paid in ETH, to compensate miners for computing resources. In summary, ETH/USD is a key trading pair in the cryptocurrency markets, representing the exchange rate between Ethereum and the U.S. dollar. Ethereum's role in supporting smart contracts, DApps, and various blockchain-based applications contributes to its importance in the broader blockchain and digital asset ecosystem.
