Vault Contract README This README provides an overview of the two Solidity contracts included in this repository: Vault.sol and ERC20.sol. These contracts facilitate the creation of a simple vault for managing ERC20 tokens.

Vault.sol Vault.sol implements a basic vault contract that allows users to deposit and withdraw ERC20 tokens. It also maintains a record of the token balance and the total supply of shares representing ownership in the vault.

Functions constructor(address _token): Initializes the vault with the address of the ERC20 token to be managed.

deposit(uint _amount): Allows users to deposit ERC20 tokens into the vault, minting shares equivalent to the deposited amount.

withdraw(uint _shares): Allows users to withdraw ERC20 tokens from the vault, burning shares equivalent to the withdrawn amount.

Variables token: Immutable variable storing the address of the ERC20 token managed by the vault.

totalSupply: Total supply of shares representing ownership in the vault.

balanceOf: Mapping storing the balance of shares for each account.

ERC20.sol ERC20.sol is a basic implementation of the ERC20 token standard. It includes functionalities such as transfer, approve, and transferFrom, along with minting and burning tokens.

Functions transfer(address recipient, uint amount): Allows the sender to transfer tokens to another address.

approve(address spender, uint amount): Approves the spender to spend a certain amount of tokens on behalf of the owner.

transferFrom(address sender, address recipient, uint amount): Allows a spender to transfer tokens on behalf of the owner, given approval.

mint(uint amount): Mints a certain amount of tokens and adds them to the total supply.

burn(uint amount): Burns a certain amount of tokens, reducing the total supply.

Variables totalSupply: Total supply of the token.

balanceOf: Mapping storing the balance of tokens for each address.

allowance: Mapping storing the allowance granted by token owners to spenders.

name: Name of the token.

symbol: Symbol of the token.

decimals: Number of decimals for the token.
