This repo contains a contract that implements tipping functionality.

Install dependencies with npm install.

Set up by creating a .env file, and filling out these variables:

GOERLI_URL="your Alchemy RPC URL"
GOERLI_API_KEY="your Alchemy API key"
PRIVATE_KEY="your wallet private key"

You can get an Alchemy RPC URL for free here.

You can get your Private Key from MetaMask like this. If you have any questions or concerns about this, please find someone you trust to sanity check you!

Deploy your contract with:

npx hardhat run scripts/deploy.js

Run an example buy coffee flow locally with:

npx hardhat run scripts/buy-coffee.js

Once you have a contract deployed to Goerli testnet, grab the contract address and update the contractAddress variable in scripts/withdraw.js, then:

npx hardhat run scripts/withdraw.js

will allow you to withdraw any tips stored on the contract.
