From f30a2c4ed4ed089f60200e2df217365d5a798d1f Mon Sep 17 00:00:00 2001 From: mindesbunister Date: Fri, 14 Nov 2025 20:53:16 +0100 Subject: [PATCH] fix: CRITICAL - Revert to Helius RPC (Alchemy breaks Drift SDK) ISSUE CONFIRMED: - Alchemy RPC does NOT support WebSocket subscriptions (accountSubscribe method) - Drift SDK REQUIRES WebSocket support to function properly - When using Alchemy: * SDK initializes with 100+ accountSubscribe errors * Claims 'initialized successfully' but is actually broken * First API call (openPosition) sometimes works * Subsequent calls hang indefinitely OR * Positions open without TP/SL orders (NO RISK MANAGEMENT) * Position Manager doesn't track positions SOLUTION: - Use Helius as primary RPC (supports all Solana methods + WebSocket) - Helius free tier: 10 req/sec sustained, 100 burst - Rate limits manageable with retry logic (5s exponential backoff) - System fully operational with Helius ALCHEMY INCOMPATIBILITY: - Alchemy Growth (10,000 CU/s) excellent for raw transaction throughput - But completely incompatible with Drift SDK architecture - Cannot be used as primary RPC for Drift Protocol trading User confirmed: 'after changing back the settings it started to act up again' This is Common Pitfall #1 - NEVER use RPC without WebSocket support --- .env | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) diff --git a/.env b/.env index 7a321ef..71833e5 100644 --- a/.env +++ b/.env @@ -31,13 +31,12 @@ API_SECRET_KEY=2a344f0149442c857fb56c038c0c7d1b113883b830bec792c76f1e0efa15d6bb # Solana RPC URL (Required for blockchain access) # -# PRIMARY: Alchemy Growth (10,000 CU/s, best for transactions) -# Used for: Transaction submission and confirmation -SOLANA_RPC_URL=https://solana-mainnet.g.alchemy.com/v2/5A0iA5UYpsmP9gkuezYeg +# PRIMARY: Helius (supports all Solana RPC methods including WebSocket subscriptions) +# Drift SDK REQUIRES WebSocket support for accountSubscribe - Alchemy doesn't support this +SOLANA_RPC_URL=https://mainnet.helius-rpc.com/?api-key=5e236449-f936-4af7-ae38-f15e2f1a3757 -# FALLBACK: Helius (for WebSocket subscriptions if needed) -# Used for: Account subscriptions (Drift SDK initialization) -SOLANA_FALLBACK_RPC_URL=https://mainnet.helius-rpc.com/?api-key=5e236449-f936-4af7-ae38-f15e2f1a3757 +# Note: Alchemy doesn't support WebSocket subscriptions, causes Drift SDK to malfunction +# SOLANA_FALLBACK_RPC_URL=https://solana-mainnet.g.alchemy.com/v2/5A0iA5UYpsmP9gkuezYeg # Alternative RPC providers (reference): #
