Encountering those moments when the "page freezes for a second," the most annoying part is that it doesn't even throw an error, as if mocking your poor internet connection. Frankly, it's probably not your computer; it's the indexer/subgraph/RPC queuing in the background: the subgraph hasn't synchronized to the latest block yet, or the indexer is rebuilding, so the frontend can only get outdated data; on the other hand, RPC rate limiting is more realistic, especially when new L1/L2 incentives boost TVL, and everyone rushes in to "mine and sell," causing request volumes to explode. If you're checking your balance/positions at that moment, you'll get a 429 or get stuck directly.
