ERC-20 Token Standard

When working with ERC-20, a token standard that defines how fungible tokens behave on the Ethereum blockchain. Also known as Ethereum token standard, it enables developers to create interoperable assets. Ethereum, the decentralized platform that runs smart contracts provides the execution environment, while smart contracts, self‑executing code that enforces token rules enforce the ERC-20 rules. Together they make it easy to launch new tokens, list them on exchanges, and integrate them into DeFi protocols.

Why ERC-20 matters for developers and traders

Understanding the ERC-20 token standard gives you a clear path from idea to market. The standard encompasses token creation, meaning every ERC-20 token follows the same set of functions (balance, transfer, allowance). Because ERC-20 requires smart contracts, developers can trust the code will run exactly as written, reducing surprise failures. Ethereum hosts ERC-20 tokens, so any wallet that talks to Ethereum can also display those tokens without extra work. DeFi platforms rely on ERC-20 because the uniform interface lets lending, swapping, and staking contracts interact without custom adapters. Crypto exchanges list ERC-20 assets, which means traders can buy, sell, and move tokens with familiar fee structures. This chain of relationships—ERC-20 → smart contracts → Ethereum → DeFi → exchanges—creates a seamless ecosystem that fuels both innovation and liquidity.

Our collection below reflects that ecosystem. You’ll find deep dives into specific ERC-20 coins, step‑by‑step guides for using wallets, security tips for handling private keys, and airdrop calendars that track free ERC-20 tokens. There are also reviews of exchanges that support ERC-20 trading pairs, comparisons of fee models, and case studies of projects that built successful economies on the standard. Whether you’re a developer planning a new token, a trader hunting the next move, or a hobbyist curious about airdrops, the posts grouped under this tag give you practical tools and real‑world examples to act on right away.
