Ethena is a protocol on the Ethereum blockchain designed to offer a synthetic dollar, aiming to create a cryptocurrency-based solution for a stable currency that operates independently of the traditional banking system. It introduces the concept of the 'Internet Bond', a savings instrument denominated in dollars, accessible globally, and built to provide a crypto-native way to save and earn interest without relying on conventional financial infrastructures.
The United States Dollar (USD) is the official currency of the United States and one of the most widely used fiat currencies in the world. Issued by the Federal Reserve, the USD serves as the global reserve currency, playing a key role in international trade, finance, and investment. Known for its stability and liquidity, the US Dollar is commonly used as a benchmark for valuing other assets, including cryptocurrencies. In the crypto space, USD is often represented through stablecoins like USDT, USDC, and DAI, which maintain a 1:1 peg to the dollar, enabling seamless digital transactions and reducing volatility.
