IOTA SDK Library

The IOTA SDK is a Rust-based project that provides a convenient and efficient way to interact with nodes in the Shimmer and IOTA networks running the Stardust protocol. It consists of two main modules: client and wallet.

Features

• Client module: The client module in the IOTA SDK offers low-level functions that allow you to have fine-grained control over your interactions with Shimmer nodes. The module is stateless. It provides access to the underlying API endpoints and enables advanced operations such as custom message construction and direct communication with the network.

• Wallet module: The wallet module in the IOTA SDK provides high-level functions for managing accounts, generating addresses, creating transactions, and interacting with the Shimmer network. It offers a user-friendly interface for developers to build applications on the Shimmer network. It is stateful, and it can optionally interact with IOTA Stronghold for seed handling, storage, and state backup.

• Bindings: The IOTA SDK includes bindings for Python, Node.js, and WASM, which allow you to use the SDK in your preferred programming language. These bindings provide seamless integration with existing projects, enabling cross-platform compatibility and flexibility.

Branching Structure for Development

This library follows the following branching strategy:

Before You Start

This file is focused on the Rust core SDK. Please refer to the Python, Node.js and Wasm instructions if you want information on installing and using them.

Requirements

The IOTA SDK requires Rust and Cargo. You can find installation instructions in the Rust documentation.

We recommend that you update the Rust compiler to the latest stable version first:

rustup update stable

Dependencies

You must also install cmake, clang, and openssl. You may need to install additional build tools on your system to run the build process successfully using Cargo.

Windows

You can download cmake from the official website. You can install openssl with vcpkg or chocolatey.

• Installing openssl with vcpkg:

./vcpkg.exe install openssl:x64-windows
./vcpkg.exe integrate install
# You may want to add this to the system environment variables since you'll need it to compile the crate
set VCPKGRS_DYNAMIC=1

• Installing openssl with chocolatey:

choco install openssl
# You may need to set the OPENSSL_DIR environment variable
set OPENSSL_DIR="C:\Program Files\OpenSSL-Win64"

macOS

You can install cmake and openssl with Homebrew:

brew install cmake openssl@1.1

Linux

You can install cmake, clang, and openssl with your distro's package manager or download them from their websites. On Debian and Ubuntu, you will also need the build-essential and libudev-dev packages.

Getting Started

Install the IOTA SDK

To start using the IOTA SDK in your Rust project, you can include the following dependencies in your Cargo.toml file:

[dependencies]
iota-sdk = { git = "https://github.com/iotaledger/iota-sdk", branch = "develop" }

Client Usage

The following example creates a Client instance connected to the Shimmer Testnet, and retrieves the node's information by calling Client.get_info(), and then print the node's information.

sdk/examples/client/getting_started.rs

Wallet Usage

The following example will create a new Wallet Account using a StrongholdSecretManager. For this features = ["stronghold"] is needed in the Cargo.toml import. To persist the wallet in a database, "rocksdb" can be added.

sdk/examples/wallet/getting_started.rs

Examples

You can use the provided code examples to get acquainted with the IOTA SDK. You can use the following command to run any example:

cargo run --release --all-features --example example_name

Where example_name is the name from the Cargo.toml name from the example folder. For example:

cargo run --release --all-features --example create_account

You can get a list of the available code examples with the following command:

cargo run --example

API Reference

You can find the IOTA SDK Rust API Reference is in the IOTA SDK crate documentation.
