ChainSig.js Simple JavaScript Example

A simple Node.js example demonstrating how to use chainsig.js in a plain JavaScript project without TypeScript.

What This Example Shows

This example demonstrates:

• ✅ How to import chainsig.js using CommonJS require()
• ✅ Accessing all available chain adapters (Bitcoin, Ethereum, Solana, etc.)
• ✅ Exploring supported chains and environments
• ✅ Understanding what's needed to initialize each adapter
• ✅ Working with the published npm package

Requirements

• Node.js (v14 or higher)
• npm

Quick Start

# Install dependencies
npm install

# Run the example
npm start

What You'll See

The example will display:

• Available chain adapters
• Supported blockchains
• Required parameters for each adapter
• Contract configuration options
• Next steps for implementation

Code Structure

• package.json - Simple CommonJS configuration with chainsig.js dependency
• index.js - Plain JavaScript code using require() syntax
• No TypeScript, no transpilation needed!

Key Differences from TypeScript Version

Simple JS	TypeScript
const chainsig = require('chainsig.js')	import * as chainsig from 'chainsig.js'
No type annotations	Full TypeScript types
No compilation step	Requires ts-node
Direct Node.js execution	Transpilation required

Next Steps

1. Choose your blockchain - Bitcoin, Ethereum, Solana, Cosmos, etc.
2. Set up chain client - Each chain needs its own client connection
3. Initialize adapter - Use the appropriate adapter with your configuration
4. Sign transactions - Use the adapter methods to sign and submit

Example Usage Patterns

Bitcoin

const { BitcoinAdapter } = require('chainsig.js');
// Need: network, contract, btcRpcAdapter

Ethereum

const { EthereumAdapter } = require('chainsig.js');
// Need: publicClient, contract

Solana

const { SolanaAdapter } = require('chainsig.js');
// Need: connection, contract

Perfect For

• Developers who prefer plain JavaScript
• Projects that don't use TypeScript
• Quick prototyping and testing
• Learning how chainsig.js works
• Integration into existing CommonJS projects

This example proves you can use chainsig.js in any Node.js project without needing TypeScript!
