Latest version



The following dependencies will be required to develop Ownables:
  • rustc and cargo versions 1.61.0 or later
  • npm version 8.11.0 or later
  • node version 16.15.0 or later
  • wasm-pack version 0.10.2 or later
If you do not have the above dependencies on your machine, see the sections below for instructions.

Rust and Cargo

Ownable packages are built with Rust.
To install Rust and its package manager Cargo, follow the official documentation guide from the Rust Book.
Verify the installation by checking the version:
$ cargo version
The version should be 1.61.0 or later.

Node & npm

npm will be needed for running the local wallet instance and building the Ownable packages.
Install it as described on the official Node.js website.
Verify the installation with:
$ npm -v
$ node -v
The node version should be 16.15.0 or later. The npm version should be 8.11.0 or later.


The smart contracts written in Rust need to be compiled to WebAssembly. This way we can easily interact with them in our wallet.
wasm-pack makes building and working with rust-generated WASM easy.
Follow the latest steps described in their official documentation to install it.
Once that is done, verify the installation:
$ wasm-pack -V
The version should be 0.10.2 or later.

Code editor (optional)

Any editor you prefer will do the job, but there are a few recommendations worth looking into here.
First is the VSCode editor which you can download from the official source. Along with it, you may consider installing this Rust plugin to help with syntax highlighting and other amenities.
Another great pick is the WebStorm by Jetbrains. JetBrains provides a Rust plugin which is very useful to help with the development flow.
