What is an Avalanche RPC Node?

Access the subnet-powered blockchain

An Avalanche RPC node provides applications with access to the C-Chain (Contract Chain), Avalanche's EVM-compatible blockchain featuring sub-second finality and high throughput. Avalanche's unique architecture combines a primary network with customizable subnets, enabling unlimited scalability while maintaining decentralization.

Why Avalanche stands out

Avalanche doesn't just offer another EVM chain — it pioneered a new consensus mechanism and introduced subnets, allowing anyone to create customized blockchains with their own rules while leveraging Avalanche's security. This architecture enables use cases from DeFi to gaming to enterprise applications, all coexisting on one platform.

Avalanche advantages:

  • Sub-2s finality — near-instant transaction confirmation
  • High throughput — 4,500+ TPS on C-Chain
  • Subnets — customizable blockchains for any use case
  • Avalanche Consensus — innovative DAG-based protocol
  • EVM compatible — full Solidity support on C-Chain
  • Strong DeFi — $1B+ TVL with major protocols

Avalanche consensus explained

Avalanche uses a novel consensus mechanism where validators repeatedly sample small random subsets of validators to determine transaction acceptance. Through metastable decision-making, the network reaches consensus with sub-second finality while maintaining high decentralization and energy efficiency.

This approach differs from both Proof of Work (slow, energy-intensive) and traditional BFT consensus (limited scalability), achieving the best of both worlds.

Avalanche architecture:

  1. Primary Network consists of three chains: X, P, and C
  2. C-Chain (Contract Chain) — EVM-compatible smart contracts
  3. X-Chain (Exchange Chain) — fast asset transfers
  4. P-Chain (Platform Chain) — staking and subnet coordination
  5. Subnets — customizable blockchains using Avalanche consensus

Subnets revolutionize scaling

Subnets are sovereign networks running on Avalanche, each with customizable rules, validators, and virtual machines. Projects can launch game-specific subnets, enterprise subnets with permissioned access, or specialized DeFi subnets — all benefiting from Avalanche's security and interoperability.

This approach enables unlimited horizontal scaling: as demand grows, new subnets can be created without impacting the primary network's performance.

Code Examples

💻

JavaScript (ethers.js) — Avalanche Connection:

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

const provider = new ethers.JsonRpcProvider('https://rpc.crypto-chief.com/avalanche/YOUR_API_KEY');

// Verify we're on Avalanche C-Chain
const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId); // 43114

// Get AVAX balance
const balance = await provider.getBalance('0x...');
console.log('AVAX:', ethers.formatEther(balance));

// Interact with Trader Joe (Avalanche's main DEX)
const JOE_ROUTER = '0x60aE616a2155Ee3d9A68541Ba4544862310933d4';
const routerABI = ['function getAmountsOut(uint, address[]) view returns (uint[])'];
const router = new ethers.Contract(JOE_ROUTER, routerABI, provider);

// Get price
const wavax = '0xB31f66AA3C1e785363F0875A1B74E27b85FD66c7';
const usdc = '0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E';
const amounts = await router.getAmountsOut(
  ethers.parseEther('1'),
  [wavax, usdc]
);
console.log('1 AVAX =', Number(amounts[1]) / 1e6, 'USDC');
💻

Python (web3.py) — Avalanche Setup:

from web3 import Web3

w3 = Web3(Web3.HTTPProvider('https://rpc.crypto-chief.com/avalanche/YOUR_API_KEY'))

print('Connected to Avalanche:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id)  # 43114
print('Latest block:', w3.eth.block_number)
print('Gas price:', w3.eth.gas_price)

# Get AVAX balance
balance = w3.eth.get_balance('0x...')
print(f'AVAX: {balance / 1e18}')
💻

WebSocket — Real-Time Avalanche Updates:

const { ethers } = require('ethers');
const provider = new ethers.WebSocketProvider('wss://rpc.crypto-chief.com/avalanche/ws/YOUR_API_KEY');

// Monitor blocks (sub-2 second finality)
provider.on('block', async (blockNumber) => {
  const block = await provider.getBlock(blockNumber);
  console.log(`AVAX block ${blockNumber}: ${block.transactions.length} txs`);
});

// Monitor USDC transfers on Avalanche
const USDC_AVAX = '0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E';
const filter = {
  address: USDC_AVAX,
  topics: [ethers.id('Transfer(address,address,uint256)')]
};

provider.on(filter, (log) => {
  console.log('USDC transfer on Avalanche:', log);
});
