Lesson outline
- A standard is a shared token interface: wallets and exchanges understand it automatically.
- ERC-20 — fungible tokens on EVM networks (BEP-20 on BSC is the same standard).
- ERC-721 / ERC-1155 — NFTs.
- SPL — Solana's token standard.
- The contract address is a token's passport: identical tickers are used by scam clones.
