How-to guide for adding upgradeability to ERC 20 contracts

This repository contains the basic implementation of Transparent & UUPS proxy patterns using Openzeppelin Upgrades Plugin.

This project is dedicated to learning and building upgradable smart contracts on Ethereum and compatible networks like Base. It serves as an educational resource for developers interested in implementing upgradeable contract patterns using Foundry and OpenZeppelin libraries.

Describes and implements some Solidity common best practices

All in one reference library for solidity, foundry, etc.,

This a minor project for the complete understanding of Upgradable smart contracts using hardhat configuration

In this project I have created an ERC20 with a multi wallet approvals upgradable contract. Without the approval of more then 2 owner the mint function will not work. In upgradable contract I have created 2 functions to upgrade 1.Change Name 2. Change Symbol.

I am using OpenZeppelin TUP strategy to upgrade the smart contracts. However, I have used my custom ERC20 contract. The upgrade feature that I have added in the ERC20 contractV2 is to change the name and the symbol.
