🚩 General Information

Each user wishing to participate must purchase 5,000 standard "TKN" erc-20 tokens
To participate, each user must deposit these tokens into the ManagerContract via the deposit function
After that, the tokens will be locked for a minute, after which the user can call the createNFT function and pass the image URI as a parameter
NFT will be minted for the user and image metadata will be added after all 10 tokens are minted
The owner of the Token contract earns 0.0001 ETH for each "TKN" token and can withdraw "TKN" from the Manager contract after unlocking the tokens.

2. 📦 Install Dependencies:

$ cd repository_file
$ npm install

3. 🔍 .env environment variables required to set up

Create .env file inside project folder

You can get your ethereum or testnet API key here,here or any other service that allow you to connect to the nodes
You can get your private key from your wallet (Don't share your private key with untrusted parties)
You can get your etherscan API -key here.
TOKEN_ADDRESS(address of TKN) be available after deploying contracts

RINKEBY_API = <Rinkeby API key>
MAINNET_API = <Ethereum mainnet API key>
PRIVATE_KEY = <Private key of your wallet u want to deploy contracts from>
ETHERSCAN_KEY = <Etherscan API key in order to verify your contracts>
