ERC-20 is a widely used standard that defines how a fungible token behaves on Ethereum and compatible networks. Fungible means each unit is interchangeable, like regular currency. By following the same rules for transfers, balances, and approvals, ERC-20 tokens work smoothly across wallets, exchanges, and DeFi apps without custom code for each one.<\/p>\n
This matters because the standard is why your wallet can display and send countless different tokens the same way. Most stablecoins, governance tokens, and airdropped tokens you encounter are ERC-20 or an equivalent on another chain.<\/p>\n
Example: a project launches its token as an ERC-20 contract, and instantly it is compatible with major wallets and DEXs because they already understand the standard.<\/p>\n
Safety note: the token approval mechanism is part of the ERC-20 standard, which is convenient but is exactly what wallet-drainers abuse. Because creating an ERC-20 is trivial, a token following the standard is not automatically safe or valuable. Verify the contract address from official sources before trusting a token. Related terms include token approval, ERC-721, smart contract, and token vs coin.<\/p>\n","protected":false},"excerpt":{"rendered":"
