Token Standards: Common Rules for Blockchain Tokens
Token standards define how tokens are created, operate, and interact with applications, enabling wallets, platforms, and smart contracts to identify and use digital assets in a consistent manner.
What Is the Purpose of Token Standards?
A token standard is a set of rules, protocols, and specifications that describe the behavior of digital tokens and how they interact. It provides a common framework for token contracts and related applications, helping tokens remain consistent, compatible, and easy to integrate across different wallets, platforms, and blockchain applications. It is an important foundation for understanding digital asset management and DeFi applications.
Standards in the Ethereum Ecosystem
ERC-20 defines a common interface for Ethereum fungible token contracts, facilitating integration with applications, trading platforms, and wallets.ERC-721 is designed for non-fungible tokens with unique identifiers and can record the on-chain ownership of digital art, collectibles, and similar assets; the token standard itself does not guarantee the authenticity or legal rights associated with off-chain items.
BNB Standards in the Chain Ecosystem
BEP-20 is used for BNB Smart Chain and supports the integration of tokens and applications on that network.BEP-2, by contrast, is BNB a historical standard used by the Beacon Chain.BNB Chain’s official Fusion record states that the Beacon Chain has completed its decommissioning process, so _2__ can no longer be described as a token issuance pathway that is still operating normally; existing assets must be handled according to the official recovery rules.BEP-2
Standards in the Solana Ecosystem SPL
SPL is a set of token rules and protocols for the Solana network, defining token behavior and interaction methods. Tokens that comply with this standard can work with Solana wallets and smart contracts. This shows that different blockchains generally use their own standards, so the target network and application scenario should be confirmed first when choosing one.
