• Run the tests script under ./test.

  npx hardhat test
  

• Deploy and verify the Smart Contract.

  npx hardhat run ./scripts/deploy.ts --network goerli
  

• Test the Deployed Smart Contract using scripts/useToken.ts. Change the global variable tokenAddress with the deployed token address. To run the script -

Note: ./scripts/useToken.tsx script can be directly used in React Frontend to interact with the smart contract.

Onchain Whitelisting

1. Architecture for Storing whitelist on chain (not optimized will consume a lot of gas while changing whitelist and blacklist accounts)

2. Architecture for Storing Whitelist offchain and using merkle root onchain. (any time admin makes changes to whitelist/blacklist addresses they just need to update merkle root on chain, which is gas efficient)
