WebSocket vs gRPC Streaming — Two Pipelines to Real-Time Solana Data

For weeks, I've been running my bot on WebSocket subscriptions. `accountSubscribe` here, `programSubscribe` there — the data flows in, my code reacts, and life seems straightforward. Then one morning,...

Jito Auction Timing — What 200ms Means

I now understand the ratio. Tip divided by compute units. The ranking formula. The efficiency metric. I have spent time trimming compute units, recalculating tip amounts, engineering leaner bundles. T...
