Cursed inscriptions are digital artifacts that didn’t receive an inscription number because they were not indexed and recognized by the Ord software. The term cursed inscriptions emerged when it was discovered that some people had inaccurately used or intentionally misused opcodes to create inscriptions, leading to digital artifacts that the Ord software couldn’t identify. A total of 472,043 Cursed Inscriptions exist, numbered from -1 to -472,043. Among them, the Yin Yang Inscriptions stand out for their unique nature, formed by the fusion of positive and negative inscriptions on the same sat. The window to grab negative inscriptions is now closed.
