Imagine there is a contract that can execute any code you send to it. And imagine it also holds some money. How easy would it be to hack it? It would be quite easy, especially if all the opcodes are available. That’s why I decided to create a puzzle like this, but with a few extra tricks to make it a bit harder to solve (even if the tricks are mostly “smoke and mirrors”). I announced the puzzle on Twitter two days before 2023, and it has already been solved: https://twitter.com/0x796/status/1...
