+__TBA challenge__: TBA
 
-__Solidity challenge__: a security audit might reveal what the developers think is private might actually not be.

-__Rust challenge__: work with RSA cryptography and math. The correct math will return you the flag.

-__ink! challenge__: you need to get the flag from an already running Substrate node or find "another" way. Make sure to web2 scan everything.

-__Kusamaverse challenge__: find the flag in Kusamaverse - this one is very easy, but important for the main event.
