When working with ERC-20, a technical specification that defines how fungible tokens behave on the Ethereum blockchain. Also known as Ethereum token standard, it provides a common set of functions that let wallets, exchanges and dApps interact with any token that follows the rules. ERC-20 unlocks seamless transfer, balance queries and allowance management, which is why developers choose it for everything from stablecoins to game assets. The standard lives inside Ethereum, the decentralized platform that runs smart contracts and powers most public blockchains today, and it relies on smart contracts, self‑executing code that enforces token rules without a central authority. Together they create a framework where any developer can launch a token in minutes, while users enjoy a predictable experience across wallets and services.
Because ERC-20 lives on Ethereum, it has become the backbone of the DeFi ecosystem. Platforms like Uniswap, Aave and Compound treat ERC-20 tokens as liquidity providers, collateral, or reward assets, which means the standard directly fuels lending, borrowing and automated market making. Tokenomics—the economic design behind a token—often leans on ERC-20 features such as totalSupply, decimals and transfer events to shape inflation rates, distribution models and governance rights. When a new project launches an airdrop, the ERC-20 contract makes it easy to snapshot holder balances and automate token distribution, a process reflected in many of the guides on this page. Moreover, crypto exchanges list ERC-20 tokens by default, because the shared interface reduces integration effort and minimizes security risks. This tight link between ERC-20, DeFi, tokenomics and exchange listings explains why the standard continues to dominate new token launches and why you’ll see it referenced in every article below.
Below you’ll find a curated set of articles that dive deep into ERC-20‑related topics. From state‑channel scaling that affects how ERC-20 transfers are batched, to step‑by‑step airdrop claims, exchange reviews and token risk assessments, the collection covers practical use‑cases, technical nuances and market perspectives. Whether you’re a developer looking for implementation tips, an investor assessing token safety, or a hobbyist hunting the next airdrop, the posts here give you actionable insights anchored in the ERC-20 framework. Keep scrolling to explore each guide, review and analysis that builds on the standard’s core principles.
