Ethereum – Everything You Need to Know

When working with Ethereum, a programmable blockchain that lets developers build decentralized applications. Also known as ETH, it powers a wide range of crypto projects and services.

Look, Ethereum isn’t just another coin. It introduced smart contracts, self‑executing code that runs on the Ethereum blockchain. These contracts replace paperwork, automate payouts, and let anyone launch a mini‑bank without a license. That means developers can build anything from games to insurance policies directly on the chain.

One of the biggest outcomes of smart contracts is the rise of ERC‑20 tokens, a token standard that defines how fungible assets are created and transferred on Ethereum. With a single line of code you can mint a new currency, a voting right, or a reward point. The standard makes wallets, exchanges, and dApps talk the same language, which is why you see thousands of projects using it.

Those thousands of tokens fuel Decentralized Finance, financial services built on blockchain that operate without traditional intermediaries. DeFi lets you lend, borrow, trade, or earn yield without a bank. Because it runs on ERC‑20 assets, you can move money instantly across the globe, earn interest on stablecoins, or swap tokens at any hour. The whole ecosystem leans on crypto exchanges to provide liquidity and price data.

Real‑world news keeps reshaping the picture. China’s 2025 ban, India’s 30 % tax, and new airdrop programs all affect Ethereum users. Exchanges that comply with local rules become safer places to trade, while regulatory shifts can trigger price swings. At the same time, developers keep rolling out tools to track real‑time ETH prices, compare gas fees, or set alerts for new token listings.

Below you’ll find a hand‑picked collection of guides, reviews, and analysis that dive deeper into each of these topics. Whether you’re checking the latest airdrop, learning how to calculate crypto taxes, or comparing exchange fees, the articles are organized to give you quick, practical answers.
