Recently, I got "scammed again by on-chain data"… I clearly saw that my position health was okay, but it took a few minutes to refresh the real status, almost thought I was seeing things. Later, I thought about it and it made sense: the on-chain data you see is always the "past" because there's a chain, with nodes, RPC, and index services in between, any hiccup can make you see outdated info. Especially when the market fluctuates, RPC rate limiting, node desynchronization, index delays—those numbers on the page can be quite mysterious.

Now there are a bunch of AI agents and automated trading talking up a storm, but I care more about which RPC provider they use, how they handle retries on failure, whether they seriously deal with nonce/replay issues… Honestly, anyone can talk about the narrative, but security and latency are things you have to figure out yourself. Anyway, when I encounter critical operations, I check two sources, even if it’s slower—better than playing with liquidation lines like a spring.
