Minimal Next.js frontend for the Tezos X testnet USDC / xU3O8 pool (ParkSwap).

npm install
npm run dev

Open http://localhost:3000.

• Connects to an injected wallet like MetaMask or Rabby
• Detects whether the wallet is on ParkSwap / Tezos X testnet (127124)
• Shows live USDC and XU3O8 wallet balances
• Reads the live pool price from the deployed pool
• Quotes swaps with the deployed quoter
• Approves tokens for swap and liquidity
• Swaps USDC ↔ XU3O8
• Adds a full-range liquidity position with fixed defaults

• USDC: 0xB155450Fbbe8B5bF1F584374243c7bdE5609Ab1f

• The app uses the public demo RPC: https://demo.txpark.nomadic-labs.com/rpc
• The swap flow is intentionally MVP-simple and uses amountOutMinimum = 0
• The liquidity action uses the existing fee tier 2500 and full-range ticks
