How to Build a Solana Wallet Tracker for Real-Time Whale Alerts
A production Solana tracker must convert raw account activity into reliable economic events while the signal is still actionable.

Signal design
Define swaps, first-time buys, exchange transfers, liquidity changes and wallet-cluster activity. Filter rent refunds, wrapped SOL account creation and dust. Thresholds should vary by wallet and market liquidity.
Ingestion
Polling is suitable for prototypes; WebSockets and Yellowstone gRPC reduce latency for larger watchlists. Keep a fallback RPC for missed-slot backfill and confirmation. Compare Yellowstone and WebSockets.
Decoding
Resolve lookup tables and inner instructions, group token accounts by owner and calculate net balance changes. Classify buy, sell, transfer and liquidity actions. Preserve unknown program interactions for later decoder coverage.
Delivery and controls
Queue normalized events before Telegram, Discord or webhook delivery. Use signature-based idempotency, persist the last processed slot and monitor lag, reconnects, decoder failures and end-to-end latency.
