Most probably, in texting, cya stands for "See You". This is typically the case in informal talks. But it is also possible that in a business or legal setting a CYA means "Cover Your Actions" or "Cover Your Assets". The context very often helps to figure out what it is. Besides that, if a person is seeking a "what does cya mean" type of answer, then in all likelihood, that person will consider the goodbye phrase as the main cya meaning reference. The cya meaning in texts is still very straightforward and friendly. It remains one of the most popular ways of saying 'goodbye' among friends, schoolmates, and people who interact in various online platforms and communities.
