Overview

Synopsis

Setup your development environment with the essentials to get started building the blockchain.

System Requirements

Before you can install and interact with spawn, you must have the following core tools installed:

• Go 1.22+
• Docker
• Git

If you do not have these components installed, follow the instructions below to install them.

Install Dependencies

Install VSCode if you do not already have a file editor. Once installed, the following extensions are useful

• Golang Syntax Highlighting
• Protobuf 3 Highlighting
• Improved Errors

MacOS

# Setup Homebrew (https://brew.sh/)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
sudo echo 'export PATH=$PATH:/opt/homebrew/bin' >> ~/.zshrc

# Base
brew install make wget jq gh gcc go

# (optional) Github CLI login
# gh auth login

# Docker
brew install --cask docker

# Start docker desktop
open -a Docker
# settings -> General -> Start Docker Desktop when you sign in to your computer
# Apply & Restart

# Setup base git config
git config --global user.email "yourEmail@gmail.com"
git config --global user.name "Your Name"

Windows (WSL)

# Install WSL in powershell
wsl --install

# Setup WSL Ubuntu Image
wsl.exe --install -d Ubuntu-24.04

# Open wsl instance
wsl

# update and add snap if not already installed
sudo apt update && sudo apt install snapd

# Install Go (https://go.dev/wiki/Ubuntu)
sudo apt update
sudo apt install golang -y

# Install Base
sudo apt install make gcc git jq wget -y

# Optional: Install github-cli

sudo snap install docker

# Fix versioning for interaction of commands
sudo chmod 666 /var/run/docker.sock

# Setup base git config
git config --global user.email "yourEmail@gmail.com"
git config --global user.name "Your Name"

After installing VSCode and having your system setup, open a terminal and run code to open vscode. You can open the current directory with code ., where . in computer terms stands for the current directory.

Linux (Ubuntu)

# Base

# (optional) Github CLI - https://github.com/cli/cli
curl -sS https://webi.sh/gh | sh
# gh auth login

# Golang
GO_VERSION=1.23.9
wget https://go.dev/dl/go$GO_VERSION.linux-amd64.tar.gz
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go$GO_VERSION.linux-amd64.tar.gz

# Docker
sudo apt -y install docker.io

# Setup base git config
git config --global user.email "yourEmail@gmail.com"
git config --global user.name "Your Name"

CosmWasm (Rust)

Some tutorials require CosmWasm (Rust smart contracts) setup. This section is option, unless a tutorial is CosmWasm focused.

CosmWasm requires Rust. You must have this installed as the contract will be built locally.

# Install rust - https://www.rust-lang.org/tools/install
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Update shell env
source $HOME/.cargo/env

# or Update if you have it
rustup update

# Install other dependencies
rustup target add wasm32-unknown-unknown

cargo install cargo-generate --features vendored-openssl
cargo install cargo-run-script
