Ācārya Kundakunda is generally regarded as a Digambara Jain ācārya, and in Digambara tradition he is counted among the most authoritative teachers. His name is also linked with the earliest Digambara monastic lineage, the Mūla-saṅgha. ( jainpedia.org)

There is some historical uncertainty about his exact life and dates, but not about his primary association with Digambara Jainism. ( jainpedia.org)
