Interface Definition Language (IDL)

Solana IDL (Interface Definition Language) is a programming language that allows developers to define and interact with smart contracts on the Solana blockchain. It provides a standardized interface for developers to create and interact with these contracts in a seamless way, regardless of the programming language used to build them.

Solana IDL is similar to other interface definition languages used in software development, such as Protocol Buffers or Apache Thrift. It allows developers to define the inputs and outputs of their smart contracts, as well as any other functions or methods that are part of the contract’s interface.

By using Solana IDL, developers can ensure that their smart contracts are interoperable with other contracts and applications built on the Solana blockchain. This can help to increase the usability and adoption of their projects, as well as make it easier for developers to collaborate on building decentralized applications.
