const ethers = require('ethers');

function getBlock() {
          const block = window.web3.eth.getBlock('latest');
          return block
            .then(data => {

in the web3js official docs, it says baseFeePerGas is Number, but why am I getting 0x7?

I think it's hex or something else; I want it to be number I need to calculate from it.

Answer 1

Yes, baseFeePerGas: "0x7" is hexadecimal.

You can convert the HEX value like this:

let baseFeePerGasWei = parseInt("0x7", 16);
console.log(baseFeePerGasWei);
