IOTA Wallet Library

Introduction

The wallet library is a stateful package with a standardised interface for developers to build applications involving IOTA value transactions. It offers abstractions to handle IOTA payments and can optionally interact with IOTA Stronghold for seed handling, seed storage and state backup. It uses RocksDB as a database.

Branching structure for development

This library follows the following branching strategy:

Branch	Description
`develop`	Ongoing development for future releases of the networks. This branch gets merged into `staging` on releases.
`production`	The latest releases for the IOTA networks.
`staging`	The latest releases for the Shimmer networks.
other	Other branches that may reflect current projects. Similar to `develop`, they will find their way into `staging` once they are ready.

Documentation

You can find the latest version of the documentation in the official Wallet.rs documentation site. Alternatively, you can run the documentation site locally following the instructions in the documentation/README.md file.

Prerequisites

Rust and Cargo are required. Install them here.

We recommend you update Rust to the latest stable version rustup update stable. Nightly should be fine but there's a chance some changes are not compatible.

Dependencies

cmake, clang and openssl are required. In order to run the build process successfully using Cargo you might need install additional build tools on your system.

Windows

cmake can be downloaded on the official website and openssl can be installed 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

cmake and openssl can be installed with Homebrew:

brew install cmake openssl@1.1

Linux

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

Usage

To use the library, add this to your Cargo.toml:

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

Initialisation

In order to use the library you first need to create an AccountManager:

use std::path::PathBuf;

use iota_wallet::{
    account_manager::AccountManager,
    secret::{stronghold::StrongholdSecretManager, SecretManager},
    ClientOptions, Result,
};

#[tokio::main]
async fn main() -> Result<()> {
    // Shouldn't be hardcoded in production
    // mnemonic can be generated with `manager.generate_mnemonic()?` and will be the only way to recover your funds if
    // you loose the stronghold file/password, so be sure to save it securely
    let nonsecure_use_of_development_mnemonic = "endorse answer radar about source reunion marriage tag sausage weekend frost daring base attack because joke dream slender leisure group reason prepare broken river".to_string();
    let stronghold_password = "some_hopefully_secure_password";

    // Setup Stronghold secret_manager
    let mut secret_manager = StrongholdSecretManager::builder()
        .password(&stronghold_password)
        .snapshot_path(PathBuf::from("wallet.stronghold"))
        .build();

    // The mnemonic only needs to be stored the first time
    secret_manager
        .store_mnemonic(nonsecure_use_of_development_mnemonic)
        .await?;

    // Create the account manager with the secret_manager and client options
    let client_options = ClientOptions::new().with_node("http://localhost:14265")?;

    let manager = AccountManager::builder()
        .with_secret_manager(SecretManager::Stronghold(secret_manager))
        .with_client_options(client_options)
        .with_coin_type(SHIMMER_COIN_TYPE)
        .finish()
        .await?;

    // Create a new account, this will automatically generate an address
    let account = manager
        .create_account()
        .with_alias("Alice".to_string())
        .finish()
        .await?;

    println!(
        "Generated a new account with addresses {:?}",
        account.addresses().await?
    );

    Ok(())
}
