Changing to Sepolia Testnet #65

kihiuFrank · 2023-08-08T09:17:18Z

I will start with changing the network from Goerli to sepolia testnet as Goerli now requires you to have real ETH to use it.

Steps for changing to Sepolia Testnet

Update the hardhat.config.js file and deploy - npx thirdweb deploy
Copy the contract address on thirdweb and update it on client/context/index.js
Update main.jsx.

See more on how to set-up here

where did you get this rpc url?

You can create your own RPC node on Alchemy or use the publicly available nodes. Your choice.

Will this line be replaced with ,

url: process.env.SEPOLIA_RPC_URL, ???

Not necessarily. Either should be ok.

kihiuFrank · 2023-09-08T13:58:21Z

@shivam5643
The current error is different from the one above.

This time, it's because you need to polyfill the Node globals and modules to enable the web3 import to run in the browser.

First, Install the package as a dev dependency.

npm install --save-dev vite-plugin-node-polyfills

then,

Change your vite.config.js to look something like;

import react from "@vitejs/plugin-react";
import { defineConfig } from "vite";
import { nodePolyfills } from "vite-plugin-node-polyfills";

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [react(), nodePolyfills()],
  define: {
    "process.env": {},
  },
});

Hello @shivam5643
Please share your thirdweb dashboard link.

kihiuFrank · 2023-09-23T12:21:44Z

Hello @shivam5643 Please share your thirdweb dashboard link.

Or, you can test this for yourself. It's quite easy.

Get the contract abi (available on the dashboard/contracts/the contract /sources).

Also I have created a pull request on your project. Check it out.
Let me know if it will work.
