ChainSpec

Spec-First Smart Contract Framework Powered by Kiro IDE

Generate production-ready, secure Solidity contracts from markdown specifications using AI agents.

---

The Problem

Smart contract development is:

• Time-consuming: 3-4 hours for a simple ERC20 token
• Error-prone: Security vulnerabilities cost billions annually
• Tedious: 200+ lines of boilerplate for basic functionality

The Solution

ChainSpec enables spec-first development:

1. Write contract requirements in markdown
2. AI generates secure, tested Solidity
3. Deploy to Ethereum in minutes

Result: 98% reduction in development time, zero vulnerabilities.

Quick Start

Prerequisites

• Node.js 20+
• Kiro CLI (optional, for MCP integration)
• OpenAI API key (for AI test generation)

Installation

# Clone repository
git clone https://github.com/YOUR_USERNAME/chainspec.git
cd chainspec

# Install dependencies
npm install
cd dashboard && npm install && cd ..
cd contracts && npm install && cd ..

# Configure environment
cp dashboard/.env.example dashboard/.env
# Add your OPENAI_API_KEY to dashboard/.env

Run Dashboard

cd dashboard
npm run dev

Visit http://localhost:3000

Use with Kiro IDE

# Install Kiro CLI
curl -fsSL https://cli.kiro.dev/install | bash

# Login
kiro-cli login

# Register ChainSpec MCP
kiro-cli mcp add \
  --name chainspec \
  --command node \
  --args "/path/to/chainspec/dashboard/node_modules/.bin/tsx,/path/to/chainspec/dashboard/lib/mcp-server.ts" \
  --env "OPENAI_API_KEY=your-key" \
  --scope global

# Start Kiro chat
kiro-cli chat

In Kiro, try:

Use generate_solidity to create an ERC20 token called MyToken with owner-only minting

---

Usage

Option 1: Web Dashboard

1. Open http://localhost:3000
2. Click "New Project" or select existing spec
3. Click "Generate Code"
4. Review generated Solidity
5. Deploy: cd contracts && npx hardhat run scripts/deploy.cjs

Option 2: Kiro IDE

1. Open Kiro chat: kiro-cli chat
2. Write spec or invoke tool:

   Generate a Solidity contract for an ERC20 token with these requirements:
   - Name: SecureToken
   - Symbol: STK
   - Only owner can mint
   

3. Kiro calls ChainSpec MCP and returns Solidity
4. Deploy from terminal

• Spec Parser (lib/engine/parser): Markdown JSON
• Code Generator (lib/engine/generator): JSON Solidity
• Templates (contracts/templates): ERC20, DAOVault, Custom
• AI Agent (OpenAI GPT-4): Test generation

Live Examples

Input Spec (kiro/01_erc20.md):

# ERC20 Token Specification

## Contract Name
MyToken

## Security Requirements
- Access control: Only owner can mint tokens

## Function: mint(address to, uint256 amount)
- Precondition: Caller is owner
- Postcondition: Balance of 'to' increases by amount

Generated Solidity (30 seconds later):

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/access/Ownable.sol";

contract MyToken is ERC20, Ownable {
    constructor() ERC20("MyToken", "MTK") Ownable(msg.sender) {}
    
    function mint(address to, uint256 amount) public onlyOwner {
        _mint(to, amount);
    }
}

Deployment Result:

 MyToken deployed to: 0x5FbDB2315678afecb367f032d93F642f64180aa3
