🌊 Polkaflow - Visual Blockchain Workflow Builder

Polkaflow is a visual blockchain workflow builder that empowers users to design, generate, and deploy smart contracts for the Polkadot ecosystem with ease. By leveraging PolkaVM, AssetHub, and both AI-driven and manual logic code generation, Polkaflow makes blockchain development accessible for everyone—from no-code users to advanced developers.

🚀 What Does Polkaflow Do?

Visual Workflow Design: Build complex blockchain workflows for DeFi, DAOs, cross-chain bridges, and more using an intuitive drag-and-drop interface.

Flexible Flowchart Creation: Choose from three ways to create your workflow:

• AI Prompt: Describe your process in natural language and let AI generate the flowchart for you.
• Manual Builder: Construct your workflow step-by-step by adding and connecting nodes.
• Templates: Start quickly with ready-made templates and customize as needed.

Smart Contract Generation: Convert your visual workflow into optimized Solidity contracts, ready for deployment on PolkaVM and AssetHub.

AssetHub Integration: Directly manage assets, proposals, and governance within your workflows.

✨ Key Features

Three Ways to Build Workflows:

• AI Flowchart Generation: Enter a prompt and instantly create a visual workflow using AI.
• Manual Node Editing: Drag, drop, and connect nodes to build your logic visually.
• Workflow Templates: Use and customize pre-built templates for common blockchain scenarios.

Two Code Generation Options:

• AI-Powered Code Generation: Let AI produce Solidity code from your workflow or prompt.
• Custom Logic Engine: Use our hand-crafted logic engine to generate contracts from your designed flowchart—giving you more control and transparency.
• Gas Estimation: High complexity functions are highlighted and offered to deploy in Rust

🧠 Hybrid Contract Optimization & Telegram Integration

• Polkaflow analyzes generated Solidity contracts to detect gas inefficiencies.
• For gas-heavy functions, the system can auto-generate an equivalent Rust contract.
• The Rust contract is embedded into the Solidity flow for optimal execution.
• A built-in dual-mode code editor allows developers to:
  • View, edit, and compile both Rust and Solidity contracts in one place.
• Telegram API integration enables:
  • Adding a Telegram bot as a node in the workflow.
  • Receiving real-time compile and deploy notifications, including:
    • ✅ Contract address
    • 🔁 Transaction hash
    • ⛽ Gas usage

Additional Features:

• PolkaVM Optimized: Supports larger contracts (up to 100KB), faster compilation, and native Solidity execution.
• AssetHub Native: Create, manage, freeze/unfreeze, and track assets directly from your workflow.
• One-Click Deployment: Instantly deploy generated contracts to AssetHub via PolkaVM.

🧑‍💻 Prerequisites

To compile and deploy contracts using Polkaflow, you must have the following compilers installed locally:

solc (Solidity compiler)

Required for compiling standard Solidity contracts.

resolc (PolkaVM Solidity compiler)

Required for compiling contracts specifically for PolkaVM.

Download and install resolc, solc from the official PolkaVM resources or releases.

Important: Make sure both solc and resolc are available in your system's PATH so Polkaflow can invoke them for contract compilation.

🚀 Quick Start

1. Clone and Install Dependencies

git clone https://github.com/your-username/polkaflow
cd polkaflow

# Install frontend dependencies
cd frontend
npm install

# Install backend dependencies
cd ../backend
npm install

# Install XCM compiler dependencies
cd xcm-compiler
npm install
cd ..

2. Set up Environment Variables

Add your gemini API key and other configuration as needed.

3. Ensure Local Compilers

solc and resolc must be available in your PATH for contract compilation.

4. Run the Servers

Start the backend server:

cd backend
node server.js

Start the frontend development server:

cd frontend
npm run dev

The frontend will typically be available at http://localhost:5173 and the backend at http://localhost:3000.

5. Get Started

Use the dashboard to create, build, and deploy your first workflow.

💡 Innovation Highlights

• First visual builder for PolkaVM and AssetHub workflows
• AI-driven and manual logic options for both flowchart creation and code generation
• Zero external dependencies for generated contracts
• Designed for both developers and non-developers to rapidly prototype and deploy blockchain applications
