ZetaChain SDK

A comprehensive TypeScript/JavaScript SDK for ZetaChain's cross-chain infrastructure.

Installation

npm install zetachain-sdk

Quick Start

import ZetaChainSDK from 'zetachain-sdk';

const sdk = new ZetaChainSDK({
  apiKey: 'your-api-key-here'
});

// Get balances across multiple networks
const balances = await sdk.getBalances('0x742d35Cc6C7486B4E1f5312b2E6a9F9E2A91D1b0', ['ethereum', 'polygon']);

// Create a new account
const account = await sdk.createAccount('MyWallet', 'evm');

// Send a cross-chain transaction
const transaction = await sdk.sendTransaction({
  from: '0xfrom...',
  to: '0xto...',
  amount: '1000000',
  network: 'ethereum'
});

Features

• ✅ Account Management - Create, list, and manage blockchain accounts
• ✅ Balance Queries - Check balances across multiple networks
• ✅ Cross-Chain Transactions - Send transactions between different blockchains
• ✅ Network Information - Get real-time network status and details
• ✅ Address Validation - Validate addresses for different networks
• ✅ Gas Estimation - Estimate transaction fees
• ✅ Unit Conversion - Convert between different units
• ✅ Bridge Operations - Bridge assets between chains

Supported Networks

• Ethereum
• Polygon
• BSC (Binance Smart Chain)
• Solana
• Sui
• Bitcoin
• TON

API Reference

Account Management

// List all accounts
const accounts = await sdk.listAccounts();

// Create a new account
const account = await sdk.createAccount('wallet-name', 'evm');

// Delete an account
await sdk.deleteAccount('wallet-name');

Balance Operations

// Get balances for multiple networks
const balances = await sdk.getBalances(address, ['ethereum', 'polygon']);

// Get balance for a single network
const balance = await sdk.getBalance(address, 'ethereum');

Transaction Operations

// Send a transaction
const tx = await sdk.sendTransaction({
  from: '0xfrom...',
  to: '0xto...',
  amount: '1000000',
  network: 'ethereum'
});

// Estimate gas costs
const gasEstimate = await sdk.estimateGas('ethereum', 'transfer');

Network Operations

// Get network information
const networkInfo = await sdk.getNetworkInfo('ethereum');

// Get all supported networks
const networks = await sdk.getSupportedNetworks();

Cross-Chain Operations

// Get cross-chain quote
const quote = await sdk.getCrossChainQuote('ethereum', 'polygon', '1000000');

// Bridge assets between chains
const bridgeTx = await sdk.bridgeAssets('ethereum', 'polygon', '1000000', fromAddress, toAddress);

Utility Methods

// Validate an address
const isValid = await sdk.validateAddress('0x...', 'ethereum');

// Convert units
const converted = await sdk.convertUnits('1', 'ether', 'wei');

TypeScript Support

The SDK is written in TypeScript and includes full type definitions:

import ZetaChainSDK, { Account, Balance, Transaction, NetworkInfo } from 'zetachain-sdk';

Error Handling

try {
  const balances = await sdk.getBalances(address);
} catch (error) {
  console.error('ZetaChain API error:', error.message);
}

Configuration

const sdk = new ZetaChainSDK({
  apiKey: 'your-api-key',
  baseUrl: 'https://custom-endpoint.com' // Optional, defaults to official endpoint
});
