Code Punks are hexadecimal (or sometimes binary) and colours inspired representations of the traditional CryptoPunks. Code Punks are unique and single edition.
Code Punks are one of my earliest Tezos memory, when hicetnunc was basically the only available platform on the chain. I collected them heavily because I love numbers and I'm still the seventh largest holder.
The artist was also developing a dedicated website with all the stats and the correspondent CryptoPunks. Have a look at https://code-punks.art/.
Sadly the project seems on a long break, months from the latest mint. If someone is in touch with the developer, please tell him to read its Twitter dms, thanks!
