Adil Oralbekuly Zhälelov, born Kulmagambetov , known professionally as Skryptonite (Russian: Скриптонит, romanized: Skriptonit), is a Kazakh rapper, singer, songwriter, and music producer. He is the founder of the record label Musica36. Skryptonite gained prominence in 2013 after releasing a music video for his debut single, «VBVVCTND». His first studio album, Dom s normalnymi yavleniyami [ru] (transl. House with Normal Activity), followed in late 2014 and became one of the most commercially successful Russian-language rap albums of 2015.
In 2018, Skryptonite divided his artistic output into two distinct projects: Skryptonite (as a solo act) and Gruppa Skryptonite (Russian: *Группа Скриптонит*; transl. Skryptonite Group). According to the artist, this separation reflects differences in both live performances and recorded material. Gruppa Skryptonite functions as an eight-member band performing reimagined arrangements, while solo Skryptonite concerts adhere to a "rapper and DJ" format with backing tracks.
In 2021, Skryptonite was named the most-streamed artist in the Commonwealth of Independent States (CIS) by the media outlet Muzyka Pervogo [ru].
