BNB Smart Chain (BSC)

GetBlock provides fast and reliable access to BNB Smart Chain nodes via JSON-RPC API. Connect to the BSC network without running your own infrastructure.

BNB Smart Chain (BSC) is a high-performance, EVM-compatible blockchain launched by Binance in September 2020. Designed to run alongside BNB Beacon Chain, BSC enables the creation and deployment of smart contracts and decentralized applications (DApps) with low transaction fees and fast block times. The network uses Proof of Staked Authority (PoSA) consensus, combining delegated Proof of Stake and Proof of Authority for high throughput and decentralization.

Key Features

• EVM Compatibility: Full Ethereum Virtual Machine compatibility for seamless dApp migration

• Fast Block Times: ~3 second block production with ~6 second finality

• Low Transaction Fees: Average fees around $0.10, significantly lower than Ethereum

• Proof of Staked Authority (PoSA): Hybrid consensus combining PoS and PoA

• 55 Validators: Decentralized validator set with staking-based governance

• BNB Token: Native token for gas fees, staking, and governance (18 decimals)

• Rich Ecosystem: 1,500+ DApps including PancakeSwap, Venus, and BakerySwap

• Cross-Chain Compatibility: Interoperability with BNB Beacon Chain

• Developer-Friendly: Compatible with MetaMask, Truffle, Remix, and other Ethereum tools

Quickstart

Javascript(Axios)

1

Setup project

Create and initialize a new project:

mkdir bsc-api-quickstart
cd bsc-api-quickstart
npm init --yes

2

Install Axios

npm install axios

3

Create file

Create a new file named index.js. This is where you will make your first call.

4

Set ES module type

Set the ES module "type": "module" in your package.json.

5

Add code

Add the following code to index.js:

index.js

const axios = require('axios');

const url = 'https://go.getblock.io/<ACCESS-TOKEN>/';

const payload = {
  jsonrpc: '2.0',
  method: 'eth_blockNumber',
  params: [],
  id: 'getblock.io'
};

axios.post(url, payload, {
  headers: { 'Content-Type': 'application/json' }
})
.then(response => {
  const blockNumber = parseInt(response.data.result, 16);
  console.log('Current Block Number:', blockNumber);
})
.catch(error => console.error(error));

Replace <ACCESS-TOKEN> with your actual access token from GetBlock.

6

Run the script

node index.js

Expected output (example):

{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": "0x4a87a53"
}
