The dashboard lets me add or edit wallets, filter buys, sells, creations, transfers, set minimum trade sizes, and pause or delete tracking. On the backend, I use Node and Express, Postgres for durable data, and Redis for price and Telegram conversation state. Helius webhooks dedupe signatures, detect which tracked wallets are involved, compute direction and SOL amount, apply filters, then send Telegram alerts. I switched from account subscribe to transaction subscribe to reduce duplicate signals and Helios token burn, and now I can track 100 to 200 wallets easily, no action requested."}
