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.

Showing how to upgrade a smart contract using another smart contract as proxy

Describes and implements some Solidity common best practices

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

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.

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

Smart contract for Transparent Proxy and UUPS with test scripts

This project demonstrates a basic Hardhat use case. It comes with a sample upgradable contract, a test for that contract, and a script that deploys that contract.

This project provides a smart contract for minting unique SVG NFTs inspired by Loogies. Attributes like color, chubbiness, and mouth length are randomized, with eye size and color added in the upgradable version. Predictable randomization without oracles ensures a straightforward and cost-effective minting process.
