Web3 Integration

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider('https://go.getblock.io/<ACCESS-TOKEN>/');

const gasPrice = await provider.getGasPrice();
console.log('Gas price:', ethers.formatUnits(gasPrice, 'gwei'), 'Gwei');

// For EIP-1559 transactions
const feeData = await provider.getFeeData();
console.log('Max fee:', ethers.formatUnits(feeData.maxFeePerGas, 'gwei'), 'Gwei');
console.log('Priority fee:', ethers.formatUnits(feeData.maxPriorityFeePerGas, 'gwei'), 'Gwei');

import { createPublicClient, http } from "viem";
import { monad } from "viem/chains";

// Create Viem client with GetBlock
const client = createPublicClient({
  chain: monad,
  transport: http(
    import.meta.env.MONAD_ACCESS_TOKEN
  ),
});

// Using the method through Viem
async function Call() {
  try {
    // Method-specific Viem implementation
    const result = await client.request({
     method: "eth_gasPrice",
     params: [],
    });
    console.log("Result:", result);
    return result;
  } catch (error) {
    console.error("Viem Error:", error);
    throw error;
