ABI (Application Binary Interface)

An Application Binary Interface (ABI) is a standardized, low-level interface that specifies how compiled applications interact with the operating system, hardware, or other software components at the binary level. In the context of blockchain, the ABI defines the methods and data structures used to interact with smart contracts, enabling different software components, such as wallets and decentralized applications (dApps), to communicate with compiled contract code on the blockchain.
