BNB Smart Chain (BSC) is a high-performance blockchain developed by Binance, offering full EVM compatibility with significantly lower transaction fees than Ethereum. BSC has become one of the leading platforms for DeFi, gaming, and NFT projects due to its speed and cost-efficiency.

Key capabilities:

  • Full EVM compatibility — deploy Ethereum contracts without changes
  • Sub-second transaction finality with 3-second block time
  • Transaction fees 20-50x lower than Ethereum
  • Native cross-chain bridges to Binance Chain
  • Thriving ecosystem with PancakeSwap, Venus, and hundreds of dApps
  • Support for BEP-20 token standard (equivalent to ERC-20)

What is a BNB Smart Chain RPC Node?

Fast and affordable blockchain infrastructure

A BNB Smart Chain RPC node provides developers with direct access to the BSC blockchain without the complexity of running infrastructure. It enables applications to read blockchain state, send transactions, interact with smart contracts, and monitor events in real-time.

Why choose BNB Smart Chain?

BSC offers the perfect balance between performance and decentralization. With 3-second block times and transaction fees often below $0.10, it's ideal for high-frequency trading, gaming, and mass-market DeFi applications that require fast execution and low costs.

BNB Smart Chain advantages:

  • Low transaction costs — 20-50x cheaper than Ethereum
  • High throughput — processes 2000+ transactions per second
  • Fast finality — 3-second blocks with quick confirmations
  • EVM compatibility — use Ethereum tools and contracts
  • Rich ecosystem — access to major DeFi protocols and exchanges

How BSC RPC works

BSC uses the same JSON-RPC interface as Ethereum, making it familiar to developers. Your application sends standard RPC calls (eth_call, eth_sendRawTransaction, etc.) to our endpoint, and receives responses from fully synchronized BSC nodes.

Request flow:

  1. Application creates JSON-RPC request with BSC-specific parameters
  2. Request sent via HTTPS or WebSocket to RPC endpoint
  3. Load balancer routes to optimal node in the cluster
  4. Node queries BNB Smart Chain and returns data
  5. Response cached for frequently requested data

HTTPS vs WebSocket for BSC

HTTPS endpoints work perfectly for standard operations — querying balances, calling view functions, sending transactions, and batch requests.

WebSocket connections provide real-time updates crucial for DEX interfaces, price feeds, NFT monitoring, and trading bots that need instant notification of new blocks and events.

Quick start for developers

Supported RPC Methods

Our BSC RPC nodes support all standard Ethereum-compatible JSON-RPC methods:

  • eth_blockNumber — current block height
  • eth_getBalance — BNB balance of address
  • eth_call — execute contract view functions
  • eth_sendRawTransaction — broadcast signed transactions
  • eth_getTransactionReceipt — transaction status and logs
  • eth_getLogs — event logs with filters
  • eth_gasPrice — current gas price (typically 3-5 Gwei)
  • eth_estimateGas — gas estimation for transactions
  • eth_subscribe — WebSocket subscriptions for real-time updates

Code Examples

💻

JavaScript (ethers.js) — Connect to BSC:

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

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

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

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

// Get BNB price from PancakeSwap
const pancakeRouter = '0x10ED43C718714eb63d5aA57B78B54704E256024E';
const routerABI = ['function getAmountsOut(uint, address[]) view returns (uint[])'];
const router = new ethers.Contract(pancakeRouter, routerABI, provider);
const amounts = await router.getAmountsOut(
  ethers.parseEther('1'),
  ['0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c', '0xe9e7CEA3DedcA5984780Bafc599bD69ADd087D56']
);
console.log('1 BNB =', ethers.formatEther(amounts[1]), 'BUSD');
💻

Python (web3.py) — BSC Connection:

from web3 import Web3

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

print('Connected to BSC:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id)  # Should be 56
print('Latest block:', w3.eth.block_number)
print('Gas price:', w3.eth.gas_price, 'wei')
💻

WebSocket — Monitor PancakeSwap Events:

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

// Monitor new blocks
provider.on('block', (blockNumber) => {
  console.log('New BSC block:', blockNumber);
});

// Monitor PancakeSwap Swap events
const pairAddress = '0x58F876857a02D6762E0101bb5C46A8c1ED44Dc16'; // WBNB-BUSD
const filter = {
  address: pairAddress,
  topics: [ethers.id('Swap(address,uint256,uint256,uint256,uint256,address)')]
};

provider.on(filter, (log) => {
  console.log('Swap detected:', log);
});

Best Practices for BSC Development

  • Gas Optimization: BSC gas is cheap but still optimize for efficiency
  • Block Confirmations: Wait 15-20 blocks for high-value transactions
  • Error Handling: Handle network congestion during peak times
  • Rate Limits: Free tier — 100,000 requests/day, paid plans for higher volume
  • Batch Requests: Combine multiple calls to reduce latency
  • WebSocket Reconnection: Implement auto-reconnect logic for stability

Binance Chain focuses on fast trading, while BNB Smart Chain supports smart contracts and dApps. BSC is EVM-compatible and runs in parallel with Binance Chain.

BSC produces blocks every ~3 seconds with transaction finality typically achieved in 15-20 blocks (45-60 seconds for high-value transactions).

Yes, BSC uses the same address format as Ethereum. Your MetaMask address works on both networks, but assets are not automatically shared between chains.

Yes, we provide RPC access to both BSC mainnet (Chain ID 56) and testnet (Chain ID 97) for development and testing.
