Crypto 101 📚 Ethereum ERC-20 Standard
ERC-20 is the technical standard for fungible tokens on Ethereum. The corresponding proposal, EIP-20, was first put forward in November 2015.
Because the interface is standardized, wallets and exchanges can recognize new tokens without having to adapt to each one individually.
Me in the past: place an order first, ask questions later. Me now: understand the rules.
ERC-20 tokens are issued on Ethereum, and each transfer requires $ETH to pay gas.
