When thinking about accounts and memos, you'll find your thinking speed much faster—compared to that, using a trading mindset seems cumbersome.

In fact, an account is an independent actor with its own state and operational rules. And memos are more like private messages transmitted between accounts, capable of carrying assets or conveying intentions. These memos are first transmitted off-chain and are only called and executed by accounts at the end.

This design approach makes the entire system's interaction logic clearer and more efficient.
