ERC Standards (ERC-20, ERC-721)
Study common Ethereum Request for Comments (ERC) standards like ERC-20 for fungible tokens and ERC-721 for non-fungible tokens (NFTs).
What are ERC Standards?
ERC stands for Ethereum Request for Comments. These are official proposals that define specific rules and functionalities for smart contracts on the Ethereum blockchain.
Think of them as blueprints or common agreements. They ensure that different contracts and applications can 'speak the same language' and interact seamlessly.
Understanding ERC-20 Tokens
An ERC-20 token is a standard for fungible tokens. Fungible means each unit is identical and interchangeable with another, just like regular currency.
If you have one dollar, it's the same as any other dollar. ERC-20 tokens are used for cryptocurrencies, stablecoins, and utility tokens.
