Protocol Interfaces

Standard

Protocol interfaces define a set of standardized functions and events that smart contracts must implement to be compatible with a particular blockchain protocol. Examples include ERC-20 for fungible tokens or ERC-721 for non-fungible tokens, which specify common methods like transfer or approve. These standards foster a cohesive and interoperable ecosystem, enabling seamless interaction between various decentralized applications. Adherence to these standards is crucial for market liquidity.
