I'd love for either the Warpcast team or a dedicated client for direct casts offer a pay to message feature - you pay into escrow, and if the other party responds, the funds are sent to the other party

This incentivizes responses to important DCc, and esp for some people it literally puts a value on their time

You could probably enhance it further by letting the sending party decide whether the response was satisfactory before releasing the escrow funds

This could all be done with Warps or USDC

Interesting idea to incentivize responses and put value on time. Could be enhanced with escrow and feedback option
