Install Requirements

Step 1: Setting Up Your Development Environment

Install Golang

Required for wasmd. Install Go from its official documentation. Ensure you have Go version v1.18+.

Install Rust

rustup is used to manage dependencies and seamlessly switch between different versions of cargo and rustc, both crucial for Rust development.

Step 2: Installing Rust (for Linux & Mac):

Begin with rustup installation.

Set up wasm32 target with the following commands:

rustup default stable
cargo version
rustup update stable
rustup target add wasm32-unknown-unknown

Installing Rust (for Windows 10):

Obtain rustup-init.exe from rustup.rs or rust-lang.org.

If needed, download Visual C++ Build Tools 2019. Ensure "Windows 10 SDK" and ''English language pack'' are selected.

Run the setup for Rust and then install the wasm32 target similarly to the Linux & Mac setup.

Step 3: Install wasmd

git clone https://github.com/CosmWasm/wasmd.git
cd wasmd
git fetch --tags
git checkout v0.27.0  # Replace with stable version if needed.
make install

Step 4: Install the Command-Line Tools:

apt install jq curl

Step 5: Choose your IDE

An Integrated Development Environment (IDE) is needed. Here are two options:

VSCode: Equipped with Rust Language Server (RLS) capabilities. Combine it with the rust-analyzer extension for optimal Rust code support.

IntelliJ IDEA Community Edition: Comes with the IntelliJ Rust plugin, providing swift inline language feature support. Particularly useful for developers familiar with IntelliJ products.

Step 6: Enhance Development

A toolset to boost the lifespan of CosmWasm smart contracts. It consists of three repositories:

CosmWasm Gitpod

Provides a ready-to-use development environment, integrating Rust, VS Code browser, crucial extensions, and Keplr wallet compatibility.

CosmWasm IDE extension

A VS Code extension simplifying the building & deployment of CosmWasm smart contracts.

CosmWasm IDE extension webview

A React application facilitating Keplr wallet interactions and enabling custom network additions.
