I just checked the on-chain data again and it froze up. A bunch of people were saying "Is there a problem with the chain?"… Actually, many times it's the indexer/subgraph tracking blocks, or RPC rate limiting. The balances, positions, liquidation lines you see are not read directly from the chain every time; more often, someone has "organized" the raw on-chain data into a table. If the organization is a bit slow, there will be gaps. Plus, when hot market conditions hit (these days, funding rates are extreme, and in the group chat, people are arguing whether to reverse or keep pumping the bubble), the request volume explodes. Free RPCs will directly give you a 429 error, and the front end just shows as "a brief freeze." I personally treat this as a risk warning: before key operations, switch to a different RPC, compare two data sources, and if you can sign locally, avoid repeatedly refreshing on the web. Anyway, I don’t dream of getting rich quick; I just hope I don’t make a mistake because of data delays.
