Getting Started

Why Use the Core API?

Interact with multiple blockchains through a single unified interface
Execute cross-chain transactions with native multi-network support
Instantly access real-time blockchain data feeds

This documentation will guide you through every step of setting up and using the Core API for developing blockchain applications.

Installation & Setup

1. Install CLI

npm install -g @elenelabs/core-api

Install the command-line interface for Core API with full network capabilities and smart contract bindings.

2. Configure Your Network

core-api init my-project --network ethereum --chain 1

Initialize a new project with Ethereum mainnet. Supported networks: Ethereum, Polkadot, Binance Smart Chain, Solana.

3. Run Development Server

cd my-project
core-api dev --watch --hot-reload
                

Live Rebuilding

Auto Reconnect

Start development server with full auto-reconnect and real-time updates across all blockchain networks.

Usage Guide

Core API Features

Basic Contract Interaction

import { ElenAPI } from '@elenelabs/core-api';

const api = new ElenAPI({
  network: 'ethereum',
  chainId: 1,
  contractAddress: '0xYourContractAddress',
  apiKey: 'YOUR_API_KEY'
});

// Read contract storage
const balance = await api.readStorage('balanceOf', {
  account: '0xUserAddress'
});

// Execute transaction
const receipt = await api.sendTransaction({
  to: '0xRecipient',
  amount: '0.1 ETH'
});
                        

Why This Matters

Cross-chain compatible contract interface
Type-safe smart contract calls
Built-in gas price estimation

Supported Method Types

Smart Contract

• Direct contract method calls
• ABI parsing tools
• Event listener system

Blockchain

• Blockchain stats
• Wallet address balance checks
• Pending transaction queries

NFT

• NFT metadata retrieval
• Token ownership tracking
• Marketplace integrations

Advanced Usage

Private Key Management

const secureConfig = {
  walletType: 'ledger',
  keyStoreType: 'keystore',
  derivationPath: "m/44'/60'/0'/0/0",
  encryption: {
    algorithm: 'AES-256-GCM',
    salt: 'secure-salt-value'
  }
};

const secureAPI = new SecureElenAPI(secureConfig);
                    

Professional-grade private key management with support for hardware wallets and encrypted keystores.

Multi-Chain Bridge

const crossChainTransfer = async () => {
  return await api.bridgeTokens({
    fromChain: 'ethereum',
    toChain: 'polygon',
    amount: '100 USDC',
    receiver: '0xReceiverAddress',
    slippageTolerance: 0.02
  });
};
                    

Seamlessly transfer tokens across chains with built-in bridge support and slippage protection.
