💼 Beat Powell

Onchain game where you can "hit" Jerome Powell to lower the Fed interest rate!

🎮 Game Mechanics

• Each hit lowers the rate by 0.01%
• Powell recovers +0.05% every hour (he fights back!)
• 1 hour cooldown between hits per wallet
• Current Fed Rate: 3.75%

🚀 Setup

1. Install dependencies

npm install

2. Deploy Smart Contract

Go to your Hardhat project folder and deploy:

npx hardhat compile
npx hardhat run scripts/deploy.js --network base

3. Configure App Environment

Create .env.local in the project root:

VITE_CONTRACT_ADDRESS=YOUR_DEPLOYED_CONTRACT_ADDRESS
VITE_PAYMASTER_URL=YOUR_PAYMASTER_URL
VITE_PUBLIC_ONCHAINKIT_API_KEY=YOUR_ONCHAINKIT_API_KEY
VITE_APP_URL=https://rate-slayer.vercel.app

• If VITE_PAYMASTER_URL is empty, transactions are sent without sponsorship.
• If it is set and supported by wallet capabilities, gas is sponsored.
• VITE_PUBLIC_ONCHAINKIT_API_KEY enables MiniKit context and compose-cast sharing.
• VITE_APP_URL is used in share links and wallet branding metadata.

4. Get Paymaster URL (optional, for gasless transactions)

1. Go to https://portal.cdp.coinbase.com/
2. Create a new project
3. Copy Paymaster URL for Base mainnet
4. Paste it into .env.local as VITE_PAYMASTER_URL

5. Run locally

npm run dev

6. Build for production

npm run build
