CRITICAL: Fix rate limiting by using dual RPC approach
Problem:
- Helius RPC gets overwhelmed during trade execution (429 errors)
- Exit orders fail to place, leaving positions UNPROTECTED
- No on-chain TP/SL orders = unlimited risk if container crashes
Solution: Hybrid RPC Strategy
- Helius for Drift SDK initialization (handles burst subscriptions well)
- Alchemy for trade operations (better sustained rate limits)
- Falls back to Helius if Alchemy not configured
Implementation:
- DriftService now has two connections: connection (Helius) + tradeConnection (Alchemy)
- Added getTradeConnection() method for trade operations
- Updated openPosition() and closePosition() to use trade connection
- Added ALCHEMY_RPC_URL to .env (optional, falls back to Helius)
Benefits:
- Helius: 0 subscription errors during init (proven reliable for SDK setup)
- Alchemy: 300M compute units/month for sustained trade operations
- Best of both worlds: reliable init + reliable trades
Files:
- lib/drift/client.ts: Dual connection support
- lib/drift/orders.ts: Use getTradeConnection() for confirmations
- .env: Added ALCHEMY_RPC_URL
Testing: Deploy and execute test trade to verify orders place successfully
