1️⃣ Home / Overview

REChain SDK is the ultimate toolkit for building scalable, interoperable, and secure blockchains.

Quick Facts:

• 🌍 Multi-chain & parachain-ready
• 🛠️ FRAME + Cumulus + XCM built-in
• 📦 Pre-built pallets & templates
• 🦀 Rust-native development

• 📚 Documentation
• 🛠️ SDK Manager
• 💬 Community Support

Quickstart

curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/REChain-Network-Solutions/SDK/master/scripts/getting-started.sh | bash

---

---

2️⃣ Getting Started

Prerequisites

• Rust & Cargo (rustc --version)
• Node.js & npm (node -v)
• WASM toolchain (wasm32-unknown-unknown target)

Steps

1. Run the quickstart script
2. Set environment variables
3. Launch node: rechain-node --version
4. Create your first chain using a template

Troubleshooting

• Check logs: ~/.rechain/logs/node.log
• Common errors & solutions table:

Error	Solution
Cargo build fails	Update Rust to latest stable
WASM compilation fails	Ensure wasm32-unknown-unknown target installed
Node won't start	Verify environment variables & ports
