Blueprint SDK

A comprehensive toolkit for building, deploying, and managing blueprints on the Tangle Network.

Overview

The Blueprint SDK is a modular Rust toolkit for building decentralized services—called Blueprints—that run across networks like Tangle, EigenLayer, and standard EVM chains.

Blueprints turn complex on-chain and off-chain infrastructure into reproducible, deployable units of logic—think Infrastructure-as-Code for crypto systems. With one SDK, you can design anything from oracles and MPC networks to agent-based AI services or zk-proof markets, and deploy them seamlessly.

The SDK unifies:

• Job orchestration and routing across async, event-driven systems
• P2P networking with secure message handling and round-based protocol support
• Cryptographic primitives and keystore management for signing, verification, and MPC
• EVM and EigenLayer extensions for direct smart contract and restaking integrations
• Testing and benchmarking utilities for reproducible environments and performance tuning

In short, Blueprints let developers move from concept to distributed protocol with minimal friction.

We also have a documentation site on all things Tangle to help you get started.

🚀 Getting Started

📋 Prerequisites

Ensure you have the following installed:

• Rust
• OpenSSL Development Packages

For Ubuntu/Debian:

sudo apt update && sudo apt install build-essential cmake libssl-dev pkg-config

For macOS:

brew install openssl cmake

🔧 CLI Installation

You can install the Tangle CLI in two ways:

🚩 Option 1: Install Script (recommended)

Install the latest stable version of cargo-tangle using the installation script:

curl --proto '=https' --tlsv1.2 -LsSf https://github.com/tangle-network/blueprint/releases/download/cargo-tangle/v0.1.1-beta.7/cargo-tangle-installer.sh | sh

🚩 Option 2: Install from source

Install the latest git version of cargo-tangle using the following command:

cargo install cargo-tangle --git https://github.com/tangle-network/blueprint --force

✨ Creating Your First Blueprint

After installation, you can create, build, and deploy your first blueprint using the following commands:

# Create a new blueprint named "my_blueprint"
cargo tangle blueprint create --name my_blueprint

# Navigate into the blueprint directory and build
cd my_blueprint
cargo build

# Deploy your blueprint to the Tangle Network
cargo tangle blueprint deploy --rpc-url wss://rpc.tangle.tools --package my_blueprint

And your blueprint is ready to go!

For additional commands, advanced configurations, and complete CLI usage, see the official CLI reference.
