BNB Smart Chain RPC Endpoint

Fast, flat-rate BNB Smart Chain RPC node provider — free tier, no KYC, HTTP & WebSocket.

BNB Smart Chain is a high-throughput EVM-compatible Layer 1 launched and operated by Binance. With sub-second block times and gas fees typically under a cent, BSC is a popular destination for retail DeFi, GameFi, and memecoin activity.

About BNB Smart Chain

BSC launched in September 2020 as a parallel chain to Binance Chain (now BNB Beacon Chain) to add EVM compatibility. It uses a Proof-of-Staked-Authority (PoSA) consensus with 41 active validators, producing blocks every ~3 seconds (recently reduced toward 1.5s via the Maxwell upgrade roadmap).

BSC is the second-largest EVM chain by daily transactions after Ethereum mainnet, driven by extremely low fees, PancakeSwap and other major DEXes, and a massive memecoin ecosystem. Smart contract semantics are identical to Ethereum — anything written for ETH compiles and deploys on BSC unchanged.

Common Use Cases on BNB Smart Chain

• Retail DeFi and yield farming (PancakeSwap, Venus)
• Memecoin and token launches
• GameFi and high-frequency dApps
• Cross-chain bridging origin/destination
• Stablecoin payments (BUSD legacy, USDT, USDC)

BNB Smart Chain Ecosystem

PancakeSwap is the dominant DEX. Other notable projects include Venus (lending), Trust Wallet, Biswap, and a deep memecoin scene. BSC processes consistently 3-5M transactions/day, more than most L2s combined.

Quick Start: Connect to BNB Smart Chain

cURL

curl -X POST https://rpc.swiftnodes.io/rpc/bsc?key=YOUR_API_KEY \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

ethers.js

import { JsonRpcProvider } from "ethers";

const provider = new JsonRpcProvider(
  "https://rpc.swiftnodes.io/rpc/bsc?key=YOUR_API_KEY"
);

const blockNumber = await provider.getBlockNumber();
console.log("BNB Smart Chain block:", blockNumber);

viem

import { createPublicClient, http } from "viem";

const client = createPublicClient({
  transport: http("https://rpc.swiftnodes.io/rpc/bsc?key=YOUR_API_KEY"),
});

const blockNumber = await client.getBlockNumber();

web3.py

from web3 import Web3

w3 = Web3(Web3.HTTPProvider("https://rpc.swiftnodes.io/rpc/bsc?key=YOUR_API_KEY"))
print("BNB Smart Chain block:", w3.eth.block_number)

Bridging to BNB Smart Chain

Use the official Binance Bridge or third-party bridges like Stargate, Multichain successors, and Squid for cross-chain transfers. Stablecoins typically use Wormhole or LayerZero variants.
