🚀 Fix: Bonding Curve Deployment & Trading Interface

[jmanhype]

🎯 Summary

This PR resolves critical issues with bonding curve deployment and trading interface functionality, enabling real blockchain deployment of bonding curves for token trading.

🔧 What Changed

1. Bonding Curve Deployment Fixes

• ✅ Split bonding curve bytecode into two environment variables (BONDING_CURVE_BYTECODE_PART1 and PART2) to handle Convex's 8KB limit per env var
• ✅ Fixed constructor arguments to match BondingCurve contract expectations (token address, fee recipient)
• ✅ Added constructor to ABI definition for proper contract deployment

2. Trading Interface Improvements

• ✅ Fixed trading interface crash by reordering React query hooks and using useAction instead of useMutation
• ✅ Fixed getUserHoldings to return single object instead of array (as expected by TradingInterface)
• ✅ Added missing database index for bonding curve transactions (by_curve_user)

3. Authentication & Routing

• ✅ Added authentication wrappers (Authenticated/Unauthenticated) to protected routes
• ✅ Fixed route definitions for Trade and Analytics pages

4. Developer Experience

• ✅ Created bytecode extraction script (scripts/extract-bondingcurve-bytecode.js) for easier deployment setup
• ✅ Added simulated trading functionality for development environment
• ✅ Updated test mocks to include bondingCurve API

🧪 Testing

• All unit tests passing ✅
• Manual testing completed:
  • Token creation ✅
  • Bonding curve deployment ✅
  • Trading interface functionality ✅
  • Analytics page ✅

📸 Screenshots

Before

• ❌ "Bonding curve contract not deployed" error
• ❌ Trading interface crashes on number input
• ❌ Authentication errors on protected routes

After

• ✅ Bonding curves deploy successfully
• ✅ Trading interface fully functional
• ✅ Smooth navigation between authenticated routes

🚀 Deployment Instructions

1. Set the following environment variables in Convex dashboard:

   BONDING_CURVE_BYTECODE_PART1=<first 8000 chars>
   BONDING_CURVE_BYTECODE_PART2=<remaining chars>
   ETHEREUM_DEPLOYER_PRIVATE_KEY=<key>
   BSC_DEPLOYER_PRIVATE_KEY=<key>
   ETHEREUM_RPC_URL=<url>
   BSC_RPC_URL=<url>
   

2. Deploy Convex functions:

   npx convex deploy
