I’d like to work on this issue because it sits at the intersection of system design, financial logic, and secure contract architecture — areas I actively specialize in and enjoy building within. The problem requires careful handling of state transitions, precision math, and security constraints, which makes it both technically meaningful and impactful to the overall reliability of the protocol.
