Getting started

ChainGate is a complete TypeScript-first framework for seamless interaction with multiple blockchain networks. Manage digital assets, query blockchain data, and execute transactions across supported networks using a unified API - all from Node.js or modern browsers.

🔐 Security first

ChainGate is designed with security in mind: Your private key never leaves your device. All signing operations, address generation, and sensitive cryptographic logic are executed locally in memory. ChainGate servers never have access to your private keys or seed phrases.

Supported blockchains

ChainGate currently supports these networks (expanded regularly):

Installation

Install ChainGate via npm:

npm install chaingate

You can obtain a free API key at ChainGate’s Dashboard.

Initialization

Start by creating a wallet with your API key. You can also import wallet from various sources such as keystore or phrase.

import { initializeWallet } from 'chaingate'

// Initialize with your API key
const { wallet, phrase } = await initializeWallet.create({
  apiKey: 'your-api-key-from-dashboard'
})

Quick Start Example

Here's how to generate an address and check balance:

import { initializeWallet } from 'chaingate'

async function main() {
  // Create Bitcoin wallet
  const wallet = await initializeWallet.create({apiKey: 'your-api-key-from-dashboard'})
  const bitcoin = wallet.currency('bitcoin')
  console.log('Bitcoin address:', await bitcoin.getAddress())

  // Get ETH balance
  const ethereum = wallet.currency('ethereum')
  const { confirmed, unconfirmed } = await ethereum.getBalance()
  console.log('ETH balance:', confirmed.str())
}

main().catch(console.error)

tip

Most of ChainGate methods return Promise-based responses for async operations. Use async/await or standard Promise handling.
