# How to Get a BNB Smart Chain (BSC) RPC Endpoint BNB Smart Chain remains one of the most active blockchains for DeFi, trading bots, and dApp development. With block times under 3 seconds and significantly lower gas fees than Ethereum, BSC handles massive transaction volumes, and your RPC infrastructure needs to keep pace. This guide walks you through setting up BSC RPC access with GetBlock, from free development endpoints to Accelerated Dedicated Nodes with private mempool support. ### Step-by-Step: Get Your BSC RPC Endpoint {% stepper %} {% step %} #### Create a GetBlock Account Go to [GetBlock Dashboard](https://account.getblock.io) and sign up. You can register with email or via Google/GitHub OAuth. {% endstep %} {% step %} #### Create a BSC Endpoint Once logged in: 1. Click **"Shared Nodes"** in the left sidebar 2. Click **"Create New Endpoint"** or the **"+"** button
3. Select: * **Protocol:** BSC * **Network:** Mainnet or Testnet * **API Interface:** JSON-RPC or Websocket or GraphQL or MEV-Protected(JSON-RPC) or MEV-Protected(Websocket) * **Region:** Frankfurt (EU) or Singapore or New York
4. Click **"Create":** Your endpoint URL will be generated immediately. {% endstep %} {% step %} #### Copy Your Endpoint URL Your endpoint URL looks like this: {% code overflow="wrap" %} ```bash https://go.getblock.io/a1b2c3d4e5f6789012345678abcdef01/ ``` {% endcode %} {% hint style="warning" %} The long string after `go.getblock.io/` is your **access token** — keep it private. {% endhint %} {% endstep %} {% step %} #### Test the Connection {% tabs %} {% tab title="cURL" %} {% code overflow="wrap" %} ```bash curl -X POST https://go.getblock.io// \ -H "Content-Type: application/json" \ -d '{ "jsonrpc":"2.0", "method":"eth_chainId", "params":[], "id":1 }' ``` {% endcode %} {% endtab %} {% tab title="Response" %} {% code overflow="wrap" %} ```bash { "jsonrpc":"2.0", "id":1, "result":"0x38" } ``` {% endcode %} {% endtab %} {% endtabs %} {% endstep %} {% endstepper %} ### Code Examples {% tabs %} {% tab title="cURL — Get BEP-20 Token Balance" %} {% code overflow="wrap" %} ```bash # Get USDT balance on BSC using eth_call curl -X POST https://go.getblock.io// \ -H "Content-Type: application/json" \ -d '{ "jsonrpc": "2.0", "method": "eth_call", "params": [{ "to": "0x55d398326f99059fF775485246999027B3197955", "data": "0x70a08231000000000000000000000000YOUR_ADDRESS_WITHOUT_0x" }, "latest"], "id": "getblock.io" }' ``` {% endcode %} {% endtab %} {% tab title="ethers.js" %} {% code overflow="wrap" %} ```javascript import { JsonRpcProvider, formatEther } from "ethers"; const provider = new JsonRpcProvider( "https://go.getblock.io//" ); // Get BNB balance const balance = await provider.getBalance("0x8894E0a0c962CB723c1ef41B18a7bb7E76FB4675"); console.log(`Balance: ${formatEther(balance)} BNB`); // Get gas price const gasPrice = await provider.getFeeData(); console.log(`Gas price: ${gasPrice.gasPrice} wei`); // Read a BEP-20 token balance (e.g., USDT on BSC) const usdtContract = new Contract( "0x55d398326f99059fF775485246999027B3197955", // BSC USDT ["function balanceOf(address) view returns (uint256)"], provider ); const tokenBalance = await usdtContract.balanceOf("0x..."); ``` {% endcode %} {% endtab %} {% tab title="Python (web3.py)" %} {% code overflow="wrap" %} ```python from web3 import Web3 w3 = Web3(Web3.HTTPProvider("https://go.getblock.io//")) print("Connected:", w3.is_connected()) print("Chain ID:", w3.eth.chain_id) # 56 for BSC Mainnet print("Latest block:", w3.eth.block_number) # Get BNB balance balance = w3.eth.get_balance("0x8894E0a0c962CB723c1ef41B18a7bb7E76FB4675") print(f"Balance: {w3.from_wei(balance, 'ether')} BNB") ``` {% endcode %} {% endtab %} {% endtabs %} ### Connect MetaMask to BSC via GetBlock 1. Open MetaMask → **Add Network** → **Add manually** 2. Enter: * **Network Name:** BSC Mainnet (GetBlock) * **RPC URL:** `https://go.getblock.io//` * **Chain ID:** `56` * **Symbol:** `BNB` * **Explorer:** `https://bscscan.com` 3.
