Space Coin ICO

Second project for the optilistic bootcamp.

An ICO with a 2% tax on every token transfer. A frontend to interact with it.

The frontend was done with react, which was probably an overkill but I wanted to try a more "real" workflow to see how everything worked.

Implemented some custom hooks too, useContract and useMetamaskAccount

In the frontend, show total contributed for each phase, total contributed overall, remaining available to contribute.
Extend the frontend to detect and show a different UI for the ICO contract owner so they can manage their contract

Running it

You can start the frontend by:

Add a .env file on the root of the project, and add the field PRIVATE_KEY
Set PRIVATE_KEY to your account's private key (so hardhat.config.js knows from which account to deploy)

Then running:

npm install
npx hardhat compile (generates the artifacts the frontend will use)
cd frontend
npm install
npm start

By default the frontend is connected to the deployed version on Rinkeby: 0xfb5C614E957162dDa1cb218002896CCC6CBCa249

If you'd like to change that:

In your env, set TREASURY_WALLET to the account that will receive the 2% tax
Run npx hardhat run scripts/deploy.js --network rinkeby
You'll get the new contract's address in your console, change it at frontend/src/utils/index.js
