Welcome to Secureum's a-MAZE-X challenge!
Within this repository you will find:
the project's dependencies
the smart contract codes
tests scripts (written in JS
)
The smart contracts to be hacked are located within the contracts
directy.
Each challenge consists of a single solidity
source file.
You can run each challenge using the hardhat tests;
Challenges are grouped in 3 different levels, and each challange awards different quantities of points to your score.
I see, you are an aspiring group of security experts... Let's check if you know your A, B, Cs with these challenges ;)
If you didn't sweat with the previous 3 contracts, it's time to turn the heat up a bit!
These contracts require more patience and attention to detail. Good luck security experts!
! An additional hint is: If the compiler does not allow implicit conversion but you are confident a conversion will work, an explicit type conversion is sometimes possible. This may result in unexpected behaviour and allows you to bypass some security features of the compiler e.g.
int
touint
. If an integer is explicitly converted to a smaller type, higher-order bits are cut off. If an integer is explicitly converted to a larger type, it is padded on the left (i.e., at the higher order end). Fixed-size bytes types while explicitly converting to a smaller type and will cut off the bytes to the right. Fixed-size bytes types while explicitly converting to a larger type and will pad bytes to the right.
If you've gotten this far, you're are on the right track for becoming the next security superstars!
This last challenge will be absolutely different to every challenge you've faced until now.
Good luck!
