Padrão de Token
Regras para criar e gerenciar tokens em um blockchain.
Garante interoperabilidade. Exemplos: ERC-20 (fungível), ERC-721 (NFT). Permite que carteiras suportem milhares de tokens com um único código.

❓ Perguntas frequentes
Why are token standards important?
They allow wallets and exchanges to support thousands of different tokens with a single codebase.
What is the most common standard?
ERC-20 on Ethereum is the most widely adopted standard for fungible tokens.
Can I upgrade a token standard?
Once deployed, the contract is immutable, but new standards (like ERC-223 or ERC-777) can be created to improve upon old ones.
