These past few days, I used Cursor to build a few practical small tools, and the experience has been pretty smooth.

The first one is an on-chain data crawler, specifically tracking all node and proxy on-chain activity data within a certain protocol ecosystem, providing real-time monitoring of who's doing what.

The second is an arbitrage monitor for prediction markets, which automatically scans for price difference opportunities. As soon as it detects asymmetric pricing, it sends a notification, saving you from exhausting manual monitoring.

The third is a message aggregator that organizes information scattered across various groups and channels. Every morning, a single notification covers all important updates, so I no longer have to constantly switch back and forth to check messages.

I used the Mac version of Cursor for these tools, and coding with it is indeed very smooth. I recommend friends with similar needs to give it a try.
