The reason why people no longer use frame tx is unclear, at least according to this Dune dashboard, and it doesn't make sense to me.

The crypto profile displays information about the user's digital assets, transactions, and balances in various cryptocurrencies, providing a comprehensive overview of their holdings.

It seems that there may be some confusion or lack of information regarding the use of frame tx. It could be beneficial to gather more data and insights to understand why people are no longer using it. It's important to consider all perspectives and potential factors before drawing conclusions.
