Installation & Setup
- ethers.js v6
- web3.js
- viem
import { JsonRpcProvider } from 'ethers';
// Connect to Polygon via Dwellir
const provider = new JsonRpcProvider(
'https://api-polygon-mainnet-full.n.dwellir.com/YOUR_API_KEY'
);
// Test connection
const blockNumber = await provider.getBlockNumber();
console.log('Connected to Polygon at block:', blockNumber);
import Web3 from 'web3';
// Initialize Web3 with Dwellir endpoint
const web3 = new Web3(
'https://api-polygon-mainnet-full.n.dwellir.com/YOUR_API_KEY'
);
// Verify connection
const chainId = await web3.eth.getChainId();
console.log('Connected to Polygon (Chain ID:', chainId, ')');
import { createPublicClient, http } from 'viem';
import { polygon } from 'viem/chains';
const client = createPublicClient({
chain: polygon,
transport: http('https://api-polygon-mainnet-full.n.dwellir.com/YOUR_API_KEY'),
});
const blockNumber = await client.getBlockNumber();
console.log('Current block:', blockNumber);

Best Practices
1. Optimize Gas Usage
Polygon has low fees, but optimizing gas usage is still important:
// Use gas estimation for accurate pricing
const gasEstimate = await contract.estimateGas.transfer(to, amount);
const gasPrice = await provider.getGasPrice();
const txCost = gasEstimate * gasPrice;
2. Handle Network Congestion
Monitor and adapt to network conditions:
// Implement dynamic gas pricing
const gasPrice = await provider.getGasPrice();
const adjustedGasPrice = gasPrice * 110n / 100n; // 10% buffer
3. Leverage Polygon's Speed
Take advantage of fast block times for better UX:
// Quick confirmation monitoring
const tx = await wallet.sendTransaction(transaction);
const receipt = await tx.wait(1); // Usually confirms in 1 block (~2 seconds)
