Token Standards (ERC-20, ERC-721, ERC-1155, BEP-20)
A token standard is a shared blueprint defining how a token behaves so wallets and exchanges can support it automatically.
In depth
ERC-20 is Ethereum’s standard for interchangeable tokens like stablecoins; ERC-721 defines unique tokens (NFTs); ERC-1155 handles both in one contract. BEP-20 is BNB Chain’s near-identical copy of ERC-20, and TRC-20 is Tron’s. The same USDT exists as separate tokens on each network.
Why it matters
Choosing the right network standard when depositing or withdrawing avoids lost funds and saves on fees.
