Hey there :) I hope you're all well

In solidity, A 'pure' function can neither modify the contract's data nor read it. Can you give example of a function that might need to be 'pure' ?
A function which adds two numbers would be an example @KshitijV97

Hey guys. I recently wrote an article which explains you step by step how you can build a full stack vending machine ethereum dapp with solidity and javascript. Maybe someone in this group might be interested!

Here is the tutorial: https://www.roheat.com/code-a-full-stack-vending-machine-ethereum-dapp-with-solidity-and-javascript/

Please feel free to check it out and leave some feedback. Thanks!

Just released the largest Ethereum Dapp tutorial ever, 5h total.
We build 5 Dapps together, and it covers smart contract, tests, and frontend

Hey y'all! We're building tools to make Ethereum development easy and Ethereum use easy, but we want to make sure we're building the right thing. If you have 2 min, can you fill out this survey? We have tons of tutorials planned with our new tools once we've validated our direction!

Hey everyone, quickly plugging in our hackathon on developing a real-world connected dApp here:
Has good cash prizes with plenty of time left to join in

Didn't find a lot of resources on how to deploy a gas free Parity PoA chain into a Kubernetes environment. I tried to keep this sample project as basic and simple as I can. Hoping it can help other people that want to play around with a gas free chain in a kubernetes environment!

@balajipachai "gas is the metric using which transactions on the ethereum blockchain are executed." whats the point of gas why isnt the fee just in ether. 1 transactoin = 0.0003 ether or whatever. whats the whole point of having gas and gas limit seems complicated for no reason

I am getting an error response from Metamask (which is intended), while I try a particular transaction. Currently, I am getting all the error info, which I don't want the user to see. Is there a way I could parse the info from the error below. I am using a try-catch mechanism to catch the Error. And the below response is stored in the err variable.

[object Object]
  "message": "VM Exception while processing transaction: revert Contract is Paused at the moment",
  "code": -32000,
  "data": {
    "0xe45338d91c0015eed4257858ad69b06b995f9b56ffced9a0f2015a369d59418c": {
      "error": "revert",
      "program_counter": 9721,
      "return": "0x08c379a000000000000000000000000000000000000000000000000000000000000000200000000000000000000000000000000000000000000000000000000000000020436f6e74726163742069732050617573656420617420746865206d6f6d656e74",
      "reason": "Contract is Paused at the moment"

The catch block:

} catch (err) {

I want to either get the message part or reason part.

I already tried multiple ways using JSON.parse(), JSON.stringify() and toString().

Any help is appreciated. Thank You in advance.
