I am applying to this issue via OnlyDust platform. Hi @b-j-roberts Can i work on this?

My background and how it can be leveraged

Worked on OP_SWAP and OP_2SWAP for Shinigami Currently lead protocol engineer at Chainrisk Labs

How I plan on tackling this issue

Use peek_bool in dstack to check for valid data at idx=0 if yes, use peek_int to get cloned data and push to top of stack

@EjembiEmmanuel Awesome, I'll assign this one to you!

@varun-doshi , thanks for the application and interest. I'll try and create another issue for you soon, since you were able to complete OP_SWAP opcodes so quickly! Thank you
