Polygon (formerly Matic Network) is a leading Ethereum scaling solution offering near-instant transactions and negligible fees. As a committed sidechain secured by Proof of Stake consensus, Polygon has become the go-to platform for DeFi, gaming, and enterprise blockchain applications requiring high throughput.

#### Key capabilities:

- Transaction fees typically under $0.01 (often <$0.001)
- 2-second block time with instant soft confirmations
- Full EVM compatibility — deploy Ethereum contracts unchanged
- Massive ecosystem with Aave, Uniswap, Quickswap, and 7000+ dApps
- Carbon-neutral blockchain through offset programs
- Native bridges to Ethereum and other chains
- Support for zkEVM and other Polygon Layer 2 solutions

## What is a Polygon RPC Node?

High-performance Ethereum sidechain infrastructure

A Polygon RPC node provides applications with direct access to the Polygon PoS blockchain, enabling fast transaction execution, smart contract interactions, and real-time event monitoring at a fraction of Ethereum mainnet costs. Polygon processes millions of transactions daily while maintaining full EVM compatibility.

### Why Polygon dominates scaling

Polygon has established itself as the leading Ethereum sidechain through a combination of ultra-low fees, fast finality, and a massive developer ecosystem. With 2-second blocks and fees often below $0.001, it enables use cases impossible on Ethereum mainnet — from microtransactions to high-frequency GameFi interactions.

**Polygon advantages:**

- **Ultra-low fees** — transactions cost fractions of a cent
- **Fast finality** — 2-second blocks with instant confirmations
- **Massive throughput** — 7000+ TPS capacity
- **Ethereum security** — secured by Ethereum through periodic checkpoints
- **Rich ecosystem** — 7000+ dApps and $1B+ TVL
- **Carbon neutral** — environmental sustainability commitment

### Polygon architecture

Polygon uses a Proof of Stake consensus mechanism with validators staking MATIC (now POL) tokens. The network periodically commits checkpoints to Ethereum mainnet for security, combining the best of sidechain scalability with Ethereum's decentralization.

**How it works:**

1. Validators produce blocks every \~2 seconds on Polygon
2. Transactions executed and finalized on the sidechain
3. Checkpoint layer periodically commits state to Ethereum L1
4. Plasma bridge enables secure asset transfers
5. Users enjoy fast, cheap transactions with L1 security guarantees

### RPC endpoint types

**HTTPS endpoints** handle standard blockchain operations — querying state, submitting transactions, calling contracts, and reading historical data.

**WebSocket endpoints** provide real-time event streaming essential for DEXs, NFT platforms, gaming, and any application requiring instant blockchain updates.

### Supported RPC Methods

Polygon supports all standard Ethereum JSON-RPC methods:

- **eth\_blockNumber** — current block height
- **eth\_getBalance** — POL/MATIC balance
- **eth\_call** — execute view functions
- **eth\_sendRawTransaction** — broadcast transactions
- **eth\_getTransactionReceipt** — transaction confirmation
- **eth\_getLogs** — event logs with filters
- **eth\_gasPrice** — current gas price (typically <30 Gwei)
- **eth\_estimateGas** — gas estimation
- **eth\_subscribe** — WebSocket subscriptions

### Code Examples

💻

#### JavaScript (ethers.js) — Polygon Connection:

```
const { ethers } = require('ethers');

const provider = new ethers.JsonRpcProvider('https://rpc.crypto-chief.com/polygon/YOUR_API_KEY');

// Verify network
const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId); // 137

// Get POL balance
const balance = await provider.getBalance('0x...');
console.log('POL balance:', ethers.formatEther(balance));

// Interact with Quickswap (Polygon's main DEX)
const quickswapRouter = '0xa5E0829CaCEd8fFDD4De3c43696c57F7D7A678ff';
const routerABI = ['function getAmountsOut(uint, address[]) view returns (uint[])'];
const router = new ethers.Contract(quickswapRouter, routerABI, provider);

// Get MATIC/USDC price
const wmatic = '0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270';
const usdc = '0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174';
const amounts = await router.getAmountsOut(
  ethers.parseEther('1'),
  [wmatic, usdc]
);
console.log('1 MATIC =', Number(amounts[1]) / 1e6, 'USDC');
```

💻

#### Python (web3.py) — Polygon Setup:

```
from web3 import Web3

w3 = Web3(Web3.HTTPProvider('https://rpc.crypto-chief.com/polygon/YOUR_API_KEY'))

print('Connected to Polygon:', w3.is_connected())
print('Chain ID:', w3.eth.chain_id)  # 137
print('Latest block:', w3.eth.block_number)
print('Gas price:', w3.eth.gas_price, 'wei')

# Very low gas price on Polygon
gas_gwei = w3.from_wei(w3.eth.gas_price, 'gwei')
print(f'Gas price: {gas_gwei} Gwei')
```

💻

#### WebSocket — Real-Time Polygon Events:

```
const { ethers } = require('ethers');
const provider = new ethers.WebSocketProvider('wss://rpc.crypto-chief.com/polygon/ws/YOUR_API_KEY');

// Monitor new blocks (every ~2 seconds)
provider.on('block', (blockNumber) => {
  console.log('New Polygon block:', blockNumber);
});

// Monitor USDC transfers on Polygon
const usdcAddress = '0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174';
const filter = {
  address: usdcAddress,
  topics: [ethers.id('Transfer(address,address,uint256)')]
};

provider.on(filter, (log) => {
  const decoded = ethers.AbiCoder.defaultAbiCoder().decode(
    ['uint256'],
    log.data
  );
  console.log('USDC transfer:', Number(decoded[0]) / 1e6, 'USDC');
});
```

### Polygon Best Practices

- **Gas Tokens:** POL (formerly MATIC) for gas, not ETH
- **Bridge Selection:** Use Polygon PoS Bridge for official transfers
- **Confirmations:** 128 blocks (\~4 minutes) for high-value transactions
- **Token Standards:** Check if using bridged vs native tokens
- **Gas Optimization:** Even with low fees, optimize contract calls
- **Reorg Handling:** Implement reorg protection for critical operations

## Got questions?  
we are here to help

## What is Polygon? 

Polygon is an Ethereum sidechain providing fast, low-cost transactions while maintaining EVM compatibility. It's secured by Proof of Stake and processes millions of transactions daily.

## How much do Polygon transactions cost? 

Polygon transactions typically cost $0.001 to $0.01, often less than a fraction of a cent. This is 100-1000x cheaper than Ethereum mainnet.

## What is the difference between MATIC and POL? 

POL is the new token that replaced MATIC in September 2024\. It serves the same purpose as gas token with enhanced tokenomics for Polygon's ecosystem expansion.

## Is Polygon secure? 

Yes. Polygon uses Proof of Stake consensus with validators securing the network. It periodically commits checkpoints to Ethereum for additional security.

## Can I use Ethereum tools with Polygon? 

Absolutely. Polygon is fully EVM-compatible, so all Ethereum tools work seamlessly — MetaMask, Hardhat, Remix, ethers.js, web3.py, and more.

## How do I bridge assets to Polygon? 

Use the official Polygon PoS Bridge at wallet.polygon.technology or third-party bridges. L1→L2 deposits take \~7-8 minutes.

## How long do Polygon withdrawals take? 

Withdrawals from Polygon to Ethereum take \~45 minutes to 3 hours depending on checkpoint submission and Ethereum network congestion.

## What is Polygon zkEVM? 

Polygon zkEVM is a separate Layer 2 using zero-knowledge proofs for even greater security and Ethereum equivalence. It's different from Polygon PoS.

## Do you support Polygon testnet? 

Yes, we provide RPC access to both Polygon mainnet (Chain ID 137) and Amoy testnet for development and testing.

## Can I deploy Ethereum contracts on Polygon? 

Yes, deploy any Ethereum contract to Polygon unchanged. Just switch RPC endpoint to Polygon and ensure you have POL for gas.
