NFT-WordOfMouth

This is the NFT base contract for Word Of Mouth. It is based on ERC1155 Upgradable Smart contract.

Steps To Run and deploy the contract

Clone the Repo

git clone https://github.com/BlockDevsUnited/NFT-WordOfMouth

cd Into the directory

cd NFT-WordOfMouth

Install the project

npm install

Compile the contract

To compile the contract, just go

npx hardhat compile

If you get any error while compiling like, hardhat not installed locally, then use

npm install --save-dev @nomiclabs/hardhat-waffle ethereum-waffle chai @nomiclabs/hardhat-ethers ethers

OR

npm install @nomiclabs/hardhat-waffle ethereum-waffle chai @nomiclabs/hardhat-ethers ethers

Test the contract

In a new terminal start a local node using:

npx hardhat node

To test the contract:

npx hardhat test --network localhost

Configuring Deployment

Now to deploy the NFT contract on the Rinkeby Testnet.

First, make sure you get some rinkeby testnet Ether. You can get some here: https://faucet.rinkeby.io/

Next, set up a rinkeby provider. You can get one from https://alchemyapi.io or from https://infura.io/

It should look like: https://eth-rinkeby.alchemyapi.io/v2/......

Next, configure module.exports in hardhat.config.js

defaultNetwork: "ropsten",
networks: {
  hardhat: {
  },
  rinkeby: {
    url: "",
    accounts: [""]
  }
},
solidity: {
  version: "0.8.0"
},
paths: {
  sources: "./contracts",
  tests: "./test",
  cache: "./cache",
  artifacts: "./artifacts"
},
mocha: {
  timeout: 20000
}

You must add your own account private key and provider url to the config

Deploy Contract

First, you must write a deploy script. Go to scripts/deploy.js in the scripts folder.

If everything is configured properly, you can now deploy. In your terminal, run the deploy command

npx hardhat run --network rinkeby scripts/deploy.js

Now copy and paste the V1 address into the " " of upgrades.upgradeProxy() in upgrade.js

npx hardhat run --network rinkeby scripts/upgrade.js

To see if your contract has been deployed, check your account in etherscan.io.

A new transaction should appear, and the transaction should deploy a new contract!

Verify on Etherscan

To verify your contract on etherscan, you must first flatten your entire contract.

npx hardhat flatten > flattenedContracts/flattenedNFTbase.sol

Take the code, and clean it up, then verify it on etherscan.

For cleaning delete all the multiple instances of SPDX-License-Identifier and pragma solidity.

Troubleshooting

If while upgrading you get any kind of error, then just remove the .openzeppelin folder and again repeat the both deploy and upgrade steps.
