In the context of smart contracts, ABI stands for Application Binary Interface. It is a crucial component in blockchain development, serving as an intermediary between two program modules, often a smart contract and the applications that interact with it.

The ABI specifies how data structures and functions are defined in a smart contract, including the types of inputs and outputs that functions require. This standardization enables different programming languages and systems to communicate effectively with the smart contract deployed on the blockchain. When developers want to call a specific function on a smart contract or retrieve data, they use the ABI to encode their requests correctly.

Understanding the ABI is essential for developers working with Ethereum or other blockchain platforms because it defines how to interact programmatically with the contract's methods and variables. Therefore, knowing what ABI stands for and its significance in the context of smart contracts is foundational for those pursuing blockchain development.
