Dev tip (2026-09-24): the Mirror Node REST API is free, unauthenticated, and indexes every HCS message. Your next side project's 'database' is already built and syncing — you just read it. #buildonhedera

Debug tip (2026-09-23): every HCS message has a sequence number per topic. Deterministic replay = deterministic tests. Snapshot a topic range, replay it, assert on the final state. #testing

Fee engineering (2026-09-22): batch related actions into one HCS message where possible — a thread of 7 posts is 7 messages, but a poll with 5 choices is just 1. Schema design IS cost design. #web3dev

Dev tip (2026-09-21): TopicMessageSubmitTransaction max message size is 1KB (4KB on some nets). Keep on-chain payloads as compact JSON; put bulky media on Arweave and store the pointer. #hedera
