how does clank.fun stream clanker trades in real time?

First, I scrape @clanker api every minute for the latest tokens and feed them into my own PostgresDB. 

an @indexsupply streaming query feeds me 100-150 trades/second from across the @base chain, I filter this for clanker trades and then fetch the latest market cap onchain with @alchemyplatform. 

I also fetch cast engagement info from @neynar. the initial feed comes from @dune.eth and I cache all metadata with Redis. 

finally the data is streamed to clients through websockets/socket.io.
