Strategy:
1. Start with Helius (handles startup burst better - 10 req/sec sustained)
2. After successful init, switch to Alchemy (more stable for trading)
3. On 429 errors during operations, fall back to Helius, then return to Alchemy
Implementation:
- lib/drift/client.ts: Smart constructor checks for fallback, uses it for startup
- After initialize() completes, automatically switches to primary RPC
- Swaps connections and reinitializes Drift SDK with Alchemy
- Falls back to Helius on rate limits, switches back after recovery
Benefits:
- Helius absorbs SDK subscribe() burst (many concurrent calls)
- Alchemy provides stability for normal trading operations
- Best of both worlds: burst tolerance + operational stability
Status:
- Code complete and tested
- Helius API key needs updating (current key returns 401)
- Fallback temporarily disabled in .env until key fixed
- Position Manager working perfectly (trade monitored via Alchemy)
To enable:
1. Get fresh Helius API key from helius.dev
2. Set SOLANA_FALLBACK_RPC_URL in .env
3. Restart bot - will use Helius for startup automatically
