Viper Contracts

Setup

To install dependencies, run:

yarn

Then create a .env file in the root directory and add the following:

localKey="your mnemonic for local development here, I usually use the phrase seen in package.json"
deploymentKey="your mainnet and testnet mnemonic goes here"
etherscanApiNew=YOUR_ETHERSCAN_API_KEY
INFURA_API_KEY=YOUR_INFURA_API_KEY

Commands available in package.json:

Test Contracts

There are three test files to cover three different contracts. They can be run all together using:

yarn test

To test a specific file you can run it directly by using:

npx hardhat test test/{filename}.js

Specific tests within a file can be disabled by adding .skip to the it function like as follows:

it.skip("should do something", async () => {
  // ...
});

Run Local Chain

To run a local chain, run:

yarn chain

Deploy Contracts

To deploy the contracts to the local network created using yarn chain, run:

yarn deploy

To deploy to a different network, you can use the --network flag:

yarn deploy --network goerli

For local development with front end app

yarn chain

in new terminal

yarn deploy --network localhost
npx hardhat run scripts/mint.js --network localhost

if you need to send yourself eth you can edit the recipient in scripts/send.js and run

npx hardhat run scripts/send.js --network localhost

Then update the contracts from the yarn deploy command in the front end.
