Using ethers.js

Connect to Helix Chain using the popular ethers.js library (v6).

Install

Terminal
npm install ethers

Read-Only Provider

JavaScript
import { JsonRpcProvider, formatEther } from 'ethers';

const provider = new JsonRpcProvider('https://rpc.thehelixchain.xyz', {
  chainId: 8088,
  name: 'helix'
});

// Get latest block number
const blockNumber = await provider.getBlockNumber();
console.log('Block:', blockNumber);

// Get balance
const balance = await provider.getBalance('0xYOUR_ADDRESS');
console.log('Balance:', formatEther(balance), 'HLX');

Send Transaction

JavaScript
import { Wallet, JsonRpcProvider, parseEther } from 'ethers';

const provider = new JsonRpcProvider('https://rpc.thehelixchain.xyz', {
  chainId: 8088,
  name: 'helix'
});
const wallet = new Wallet('YOUR_PRIVATE_KEY', provider);

const tx = await wallet.sendTransaction({
  to: '0xRECIPIENT_ADDRESS',
  value: parseEther('1.0')  // Send 1 HLX
});

const receipt = await tx.wait();
console.log('TX Hash:', receipt.hash);

Interact with HelixSwap Router

JavaScript
import { Contract, JsonRpcProvider } from 'ethers';

const ROUTER = '0x392880e8E97b4eFe0D4553D04C0f84072c87cA0B';
const ROUTER_ABI = [
  'function getAmountsOut(uint amountIn, address[] path) view returns (uint[] amounts)',
  'function swapExactETHForTokens(uint amountOutMin, address[] path, address to, uint deadline) payable'
];

const provider = new JsonRpcProvider('https://rpc.thehelixchain.xyz');
const router = new Contract(ROUTER, ROUTER_ABI, provider);

// Get swap quote: 1 HLX -> WHLX
const WHLX = '0x85341204E4988F377a813633D6d13e6f528c1cF5';
const amounts = await router.getAmountsOut(parseEther('1'), [WHLX, TOKEN_ADDRESS]);
console.log('Output:', formatEther(amounts[1]));

Using web3.js

Connect using web3.js (v4).

JavaScript
import { Web3 } from 'web3';

const web3 = new Web3('https://rpc.thehelixchain.xyz');

// Get block number
const block = await web3.eth.getBlockNumber();
console.log('Block:', block);

// Get balance
const balance = await web3.eth.getBalance('0xYOUR_ADDRESS');
console.log('Balance:', web3.utils.fromWei(balance, 'ether'), 'HLX');

// Subscribe to new blocks (WebSocket)
const web3ws = new Web3('wss://ws.thehelixchain.xyz');
const sub = await web3ws.eth.subscribe('newHeads');
sub.on('data', (block) => {
  console.log('New block:', block.number);
});

HelixSwap DEX

Uniswap V2-compatible decentralized exchange for swapping tokens on Helix Chain.

Factory
0xb692bbeD3b5b13D0078F184E791027594d2EF6d8
Router
0x392880e8E97b4eFe0D4553D04C0f84072c87cA0B

Fee structure: 0.3% per swap (0.25% to LPs, 0.05% to protocol treasury)

Interface: swap.thehelixchain.xyz

The DEX is fully compatible with the Uniswap V2 SDK and any tools that support the UniswapV2Router02 interface.


Token Launchpad

Create tokens with bonding curve pricing. Tokens graduate to HelixSwap after reaching 50,000 HLX market cap.

HelixLaunch
0x0004c38e406A28c78b2cD07f8c17227eb40bF089

Bonding curve: Linear — price = basePrice + totalSold * slope

Base price: 0.000005 HLX

Graduation: At 50,000 HLX raised, the token creates a HelixSwap liquidity pool and LP tokens are burned (permanent liquidity).

Fees: 1% on buys/sells to protocol treasury

Interface: launch.thehelixchain.xyz


NFT Marketplace

Mint, list, and trade NFTs on Helix Chain.

HelixNFT (ERC-721)
