Ethereum ERC-20 Token Overview

When working with Ethereum ERC-20, a token standard that lets developers create interchangeable assets on the Ethereum blockchain, you’re tapping into one of the most widely used building blocks of modern crypto. Also known as ERC‑20 token, a set of rules for token creation and transfer, the standard defines how smart contracts, self‑executing code on Ethereum interact with wallets and exchanges. In short, the Ethereum ERC-20 framework enables developers to launch a coin, a utility token, or a stablecoin without reinventing the wheel. This means anyone can issue a token that automatically works with most crypto exchanges, platforms that list and trade digital assets that support the standard. The result is a huge ecosystem where token creators, traders, and dApp users all speak the same language.

Why ERC-20 matters for DeFi and beyond

The ERC‑20 token standard, a set of six functions every token must implement is the backbone of decentralized finance (DeFi). Because the standard is simple, developers can focus on features like yield farming, staking, or airdrops without worrying about compatibility. For example, a token that offers staking rewards can be listed on a DEX, held in a wallet, and used in a lending protocol—all thanks to the same ERC‑20 interface. This cross‑compatibility also drives the popularity of airdrop campaigns, where projects distribute free tokens to existing ERC‑20 holders, boosting network effects. Moreover, the standard influences how exchanges design fee structures and security models, since they must validate token contract code before allowing deposits. In practice, every new DeFi tool you hear about—from liquidity pools to synthetic assets—relies on the ERC‑20 rules to move value securely and predictably across the Ethereum network.

Across the articles below you’ll see practical examples of how ERC‑20 tokens shape the market. We’ve gathered deep‑dives into exchange reviews like Resfinex, which only supports ERC‑20 assets, guides on tokenomics for coins such as CAT (SOL) and DeLorean (DMC), and comparisons of staking versus lending profitability for ERC‑20 based protocols. There are also walkthroughs of airdrop mechanics for projects like RingDAO and insights into how TVL (Total Value Locked) measures the health of ERC‑20‑centric DeFi platforms. Whether you’re a beginner testing strategies in our paper‑trading sandbox or a seasoned trader looking for the next token to add to your portfolio, this collection gives you the context and details you need to make informed moves with Ethereum ERC‑20 assets.
