Vault Manager

Description

Vault Manager is a smart contract project that helps other contracts manage ERC20 tokens and maintain whitelists for each token.

Features

• Management of ERC20 tokens
• Whitelisting functionalities
• Owner-based actions

Prerequisites

• Hardhat

Installation

1. Clone the repository:

git clone https://github.com/The-Poolz/VaultManager.git

2. Install the dependencies:

npm install

3. Run the Hardhat test:

npx hardhat test

Usage

After deploying the contracts, the owner (the deployer) can perform various operations.

From an External Contract

Deposit

To deposit tokens into a vault, the external contract should call depositByToken from VaultManager.sol. Make sure that msg.sender is set to the _from address.

Withdraw

To withdraw tokens, the external contract calls thewithdraw` function.

Owner Functionalities

If you are the owner of the deployed contracts, you have the following additional functionalities:

In VaultManager.sol

1. Set Trustee: Must be called to finish the setup and can only be called once. After that, use updateTrustee to change the trustee.
2. Set Trade Start Time: Can be used to change the trade start time initially set during vault creation with createNewVault.
3. Set Vault Royalty: Can be used to change the royalty details initially set during vault creation with createNewVault.
4. Create New Vault: This function has multiple overloads, allowing you to create new vaults with different configurations.
5. Update Trustee: You can update the trustee address using updateTrustee.

In Vault.sol

The Vault is an internal contract that is managed solely by its creator, the VaultManager contract. No one else can interact with it directly. It serves as a small internal part responsible for specific functionalities like withdraw.

1. Withdraw: The Vault Manager, which is the entity that creates the vault, has the ability to withdraw tokens to a specified address using the withdraw function.

Role of the Trustee

Only the trustee can use the tokens stored in the vaults, not the owner.
