​
What is PolyNode RPC?

PolyNode RPC is a high-performance Polygon RPC endpoint with proprietary transaction routing for priority block inclusion. It’s a drop-in replacement for any standard Ethereum RPC — just change the URL. 
https://rpc.polynode.dev

​
Why Use PolyNode RPC?

Priority Execution

90%+ of transactions land as TX #1 (first transaction in block).

Drop-In Compatible

Standard Ethereum JSON-RPC. Works with MetaMask, ethers.js, web3.py, viem, wagmi, Hardhat, Foundry — no SDK needed.

Low-Latency Routing

Proprietary infrastructure minimizes the time between submission and block inclusion.

MEV Protection

Transactions are not broadcast publicly, reducing front-running risk.

​
How It Works

  1. Your transaction arrives at our endpoint via standard eth_sendRawTransaction
  2. PolyNode’s routing engine determines the optimal delivery path
  3. Your transaction is delivered with priority for fast block inclusion
  4. Redundant delivery ensures reliability
The result: your transaction reaches block inclusion faster than transactions submitted through public RPCs.

Quick Start

1

Get an API Key

Contact us for beta access.
2

Configure Your RPC URL

Replace your existing Polygon RPC URL with:
https://rpc.polynode.dev
3

Add Authentication

Include your API key in requests:
x-api-key: your_api_key
4

Send Transactions

Use any Ethereum library — it just works:
import { createPublicClient, http } from 'viem'
import { polygon } from 'viem/chains'

const client = createPublicClient({
  chain: polygon,
  transport: http('https://rpc.polynode.dev', {
    fetchOptions: {
      headers: { 'x-api-key': 'your_api_key' }
    }
  })
})

Supported Methods

PolyNode RPC supports the standard Ethereum JSON-RPC specification. Transaction submission uses our priority routing engine. Core chain data is served directly from our infrastructure. Read methods are served with standard Polygon node responses.

All other methodsStandardFull JSON-RPC compatibility
Current-state only. State queries like eth_getBalance, eth_getStorageAt, and eth_call only support the latest block tag. Historical state at specific block numbers is not available. Block and transaction data (eth_getBlockByNumber, eth_getTransactionReceipt) works for all blocks.
