ERC-20 Token Standard Explained

When working with ERC-20, the most widely used fungible token standard on the Ethereum blockchain. Also known as Ethereum token standard, it lets developers create interchangeable digital assets that can be sent, received, and traded with a uniform set of rules. ERC-20 is the backbone of most crypto projects you see today, from stablecoins to gaming tokens. If you’ve ever bought a token on a DEX, you’ve interacted with an ERC-20 contract without even noticing it.

Understanding Ethereum, a global, open-source platform that runs smart contracts is key because ERC-20 lives entirely on this network. Ethereum provides the execution environment, the gas pricing model, and the consensus that keep ERC-20 transfers honest. When the network upgrades or changes fee structures, ERC-20 tokens feel the impact directly – higher gas means higher transaction costs for users and developers alike.

The technical magic behind ERC-20 lies in the smart contract, self-executing code stored on a blockchain that enforces agreement terms. An ERC-20 contract defines six core functions – totalSupply, balanceOf, transfer, transferFrom, approve, and allowance – that create a predictable interface for wallets and exchanges. Because every ERC-20 token follows the same template, a single wallet can manage dozens of tokens without custom code for each one.

In the world of DeFi token, a cryptocurrency used within decentralized finance applications to provide liquidity, governance, or utility, ERC-20 is the lingua franca. Yield farms, liquidity pools, and governance platforms all expect ERC-20 compliance, which lowers entry barriers for new projects. When a DeFi protocol needs a new incentive token, developers simply deploy an ERC-20 contract and plug it into the existing infrastructure. These three entities—ERC-20, Ethereum, and smart contracts—form a tight loop: ERC-20 requires a smart contract, the smart contract runs on Ethereum, and the health of the Ethereum network influences how ERC-20 tokens perform. Meanwhile, DeFi tokens amplify ERC-20’s relevance by driving demand for token swaps, staking, and governance voting.
