In this Task I have created an ERC20 Upgradable Multi Wallet signature contract. Having a multiple owners will prevent hackers to take advantage of the contract. The contracts are deployed on a BSC testnet through hardhat and the contracts addresses are mentioned. In upgradable contract I have added 2 functions that are being upgraded

1. Change Name
2. Change Symbol

1. npm install
2. npx hardhat run --network testnet scripts/deploy_ERC20M.js
3. npx hardhat verify --network testnet [Address]
4. npx hardhat run --network testnet scripts/deploy_ERC20MUpgradable.js
5. npx hardhat verify --network testnet [Address]

1. Once an ERC20 contract is deployed then there is no way it could be UPGRADED.
2. It could only be upgraded while you are deploying the very first contract.

I am using OpenZeppelin Upgrdable Proxy approach to make my ERC20 contract Upgradable.
