✅ Implement working Drift leverage trading
Key Features: - ✅ Drift SDK v2.126.0-beta.14 integration with Helius RPC - ✅ User account initialization and balance reading - ✅ Leverage trading API with real trades executed - ✅ Support for SOL, BTC, ETH, APT, AVAX, BNB, MATIC, ARB, DOGE, OP - ✅ Transaction confirmed: gNmaWVqcE4qNK31ksoUsK6pcHqdDTaUtJXY52ZoXRF API Endpoints: - POST /api/drift/trade - Main trading endpoint - Actions: get_balance, place_order - Successfully tested with 0.01 SOL buy order at 2x leverage Technical Fixes: - Fixed RPC endpoint blocking with Helius API key - Resolved wallet signing compatibility issues - Implemented proper BigNumber handling for amounts - Added comprehensive error handling and logging Trading Bot Status: 🚀 FULLY OPERATIONAL with leverage trading!
