A real-time Hyperliquid whale alert bot is a small program that listens to the exchange’s live trade feed, keeps only the trades large enough to matter, and sends you a notification the moment one happens. You can build a working…
Flashblocks are 200-millisecond pre-confirmations on Base. Instead of waiting the full two seconds for a block, your app learns that a transaction will be included in about a tenth of that time, then updates the interface before the block is…

Reading data from a blockchain sounds simple until you try it. A smart contract emits events, but pulling those events back out in a useful order — filtered, aggregated, ready for a frontend — is slow and awkward if you…
Gzip compression shrinks the JSON that a blockchain endpoint sends back to your application, so large responses download faster and burn less bandwidth. You enable it by telling the endpoint your client accepts gzip — and with most modern tooling,…
