Prerequisites

Before setting up your development environment, make sure you have these tools installed.

Required Software

For All Developers

Tool	Version	Purpose	Install
Git	Latest	Version control	`brew install git`
Docker	Latest	Local services (PostgreSQL)	Docker Desktop
Node.js	^22.0.0	Frontend runtime	`brew install node@22` or use nvm
npm	Comes with Node	Frontend package manager	Included with Node.js

For Backend Development

Tool	Version	Purpose	Install
Rust	1.90+	Backend language	`curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs \	sh`
cargo	Comes with Rust	Rust package manager	Included with Rust

For Smart Contract Development

Tool	Version	Purpose	Install
Node.js	^22.0.0	Hardhat runtime	Same as frontend
Hardhat	2.26.0	Contract framework	Installed via npm (project dependency)

Access Requirements

You'll need access credentials for:

Service	What You Need	Who Provides It
GitHub repository	SSH key or PAT	Team lead
PostgreSQL (local)	Auto-configured by Docker	Docker Compose
PostgreSQL (stage)	Connection string	DevOps / GitHub Secrets
RPC endpoints	API keys	Team lead
Dynamic Labs	Environment ID	Team lead

Hardware Recommendations

Component	Minimum	Recommended
RAM	8 GB	16 GB (Rust compilation is memory-heavy)
Storage	20 GB free	50 GB free (Docker images, build cache)
CPU	4 cores	8 cores (parallel Rust compilation)

Verify Installation

# Check Git
git --version

# Check Docker
docker --version
docker compose version

# Check Node.js
node --version    # Should be >= 22.0.0
npm --version

# Check Rust (if doing backend work)
rustc --version   # Should be >= 1.90
cargo --version

# Check all tools at once
echo "Git: $(git --version)" && \
echo "Docker: $(docker --version)" && \
echo "Node: $(node --version)" && \
echo "npm: $(npm --version)" && \
echo "Rust: $(rustc --version 2>/dev/null || echo 'not installed')"
