How to Connect to Avalanche

Using ethers.js

const { ethers } = require('ethers');

const provider = new ethers.JsonRpcProvider(
  'https://rpc.ankr.com/avalanche'
);

const balance = await provider.getBalance('0x...');

Using web3.js

const Web3 = require('web3');
const web3 = new Web3('https://rpc.ankr.com/avalanche');

const balance = await web3.eth.getBalance('0x...');

Avalanche-specific Considerations

  • Chain ID: 43114 for Mainnet, 43113 for Fuji (Testnet)
  • Block Time: ~1 second (very fast!)
  • Gas Token: AVAX (not like Ethereum's ETH)
  • Transaction Types: EVM transactions work similarly to Ethereum
