BlockRazor’s RPC mode is the most straightforward way to submit transactions to supported networks. It exposes the full suite of standard JSON-RPC methods — including eth_sendRawTransaction — while layering in MEV protection and real-time rebate support on top of your existing workflow. Because the interface is 100% JSON-RPC compatible, migrating from a public RPC endpoint requires nothing more than swapping the URL.

​
Supported Chains

BSC

Full JSON-RPC method support including eth_sendRawTransaction. No rate limits for new registered users.

Ethereum

Full JSON-RPC method support including eth_sendRawTransaction. No rate limits for new registered users.

Base

Supports eth_sendRawTransaction. New users are rate-limited to 1 Tx / 5 seconds.

Monad

Standard JSON-RPC submission with BlockRazor’s acceleration network. Coming soon.
New registered users on BSC and Ethereum have no rate limits. Base is restricted to 1 transaction every 5 seconds for new accounts. Subscribe to a plan to remove limits and unlock higher throughput.

​
Endpoint Format

All BlockRazor RPC endpoints follow this pattern: 
https://rpc.blockrazor.io/<chain>?auth=<your-token>
You can also pass the token as an Authorization header instead of a query parameter. See the examples below for both approaches.
Don’t have an auth token yet? Visit the Authentication guide to generate one from the BlockRazor dashboard.

Connecting to BlockRazor RPC

​
cURL

curl -X POST https://rpc.blockrazor.io/bsc \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_AUTH_TOKEN' \
  -d '{"jsonrpc":"2.0","method":"eth_sendRawTransaction","params":["0xSIGNED_TX_HEX"],"id":1}'

​
ethers.js

import { ethers } from "ethers";

const provider = new ethers.JsonRpcProvider(
  "https://rpc.blockrazor.io/bsc?auth=YOUR_AUTH_TOKEN"
);

// Sign and send a transaction
const wallet = new ethers.Wallet("YOUR_PRIVATE_KEY", provider);
const tx = await wallet.sendTransaction({
  to: "0xRECIPIENT_ADDRESS",
  value: ethers.parseEther("0.01"),
});

console.log("Transaction hash:", tx.hash);
await tx.wait();
console.log("Transaction confirmed!");

​
Web3.js

import Web3 from "web3";

const web3 = new Web3("https://rpc.blockrazor.io/bsc?auth=YOUR_AUTH_TOKEN");

const signedTx = await web3.eth.accounts.signTransaction(
  {
    to: "0xRECIPIENT_ADDRESS",
    value: web3.utils.toWei("0.01", "ether"),
    gas: 21000,
  },
  "YOUR_PRIVATE_KEY"
);

const receipt = await web3.eth.sendSignedTransaction(signedTx.rawTransaction);
console.log("Mined in block:", receipt.blockNumber);

​
Key Methods

eth_sendRawTransaction

Submit a signed, serialized transaction. The primary method for all EVM-compatible chains.

eth_getTransactionReceipt

Poll for transaction status and retrieve block inclusion details after submission.

eth_blockNumber

Retrieve the latest confirmed block number on the target chain.

eth_call

Execute a read-only contract call without broadcasting a transaction.
BlockRazor’s RPC mode supports the full Ethereum JSON-RPC specification. Any method valid on the target chain’s native RPC is also valid on the BlockRazor endpoint.
