SDKs and Tools - Overview
Introduction
One can (programatically) interact with the MultiversX Network by leveraging the following SDKs, tools and APIs:
sdk-rs - Rust SDK
Note that Rust is also the recommended programming language for writing Smart Contracts on MultiversX. That is, Rust can be used to write both on-chain software (Smart Contracts) and off-chain software (e.g. desktop applications, web applications, microservices). For the on-chain part, please follow Smart Contracts. Here, we refer to the off-chain part.
| Name | Description |
|---|---|
| sdk-rs | Rust SDK used to interact with the MultiversX Blockchain. This is the parent repository, also home to the Rust Framework for Smart Contracts. |
| sdk-rs/core | Core components, accompanied by a set of usage examples. |
| sdk-rs/snippets | Smart Contract interaction snippets - base components. Examples of usage: adder, multisig. |
