Sahara is a contact class and library lookup tool for Starknet.
Taking inspiration from object-oriented programming, StarkNet distinguishes between a contract and its implementation by separating contracts into classes and instances.
A contract class is the definition of the contract: Cairo byte code, hint information, entry point names, and everything that defines its semantics unambiguously. Each class is identified by its class hash, which is analogous to a class name in an object oriented programming language. A contract instance is a deployed contract corresponding to some class. Notice that only contract instances behave as contracts in that they have their own storage and can be called by transactions or other contracts.
A contract class does not necessarily have a deployed instance in StarkNet.
Currently, a developer needs to use starknet-cli get_class_by_hash command in order to get json compilation file of the class contract. This json file is not easy to read. Also, finding a deployed contract's hash and lookup for the compilation file is a two-step process.
Sahara parses the ABI of the class or library related to given class hash and visualizes the ABI to the dev.
Sahara is started in Starknet Paris Hackathon(2022). Shahar Papini has inspired me to do this project. Due to some unfortunate things I had at the hackathon time, I delivered only a static version of Sahara that represents the idea.
This is a standalone project for now. However, integrating sahara into a starknet explorer seems to be a better path.
