Web3 Integration

import { ethers } from 'ethers';

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

// Using ethers provider methods
const result = await provider.send('eth_coinbase', []);
console.log(result);

import { createPublicClient, http } from 'viem';
import { sei } from 'viem/chains';

const client = createPublicClient({
    chain: sei,
    transport: http('https://go.getblock.io/<ACCESS-TOKEN>/')
});

// Using viem's request method
const result = await client.request({
    method: 'eth_coinbase',
    params: []
});
