Yes. In Jainism there isn’t a universal ban on salted peanuts for lay followers. Salted peanuts are generally allowed as long as they are prepared without harming living beings and fit your personal vows and dietary rules. Some individuals or communities may choose to avoid legumes or certain snacks for personal or sectarian reasons, but this is not a universal rule across Digambar and Shwetambar traditions.

If you have specific vows (like avoiding certain foods) or belong to a particular community, you may want to check with your guru or local Jain center.
