Who among the following Vedic deities was considered the guardian of compacts and marriages?

In the Vedic pantheon, Aryaman is one of the Adityas (solar deities) and is specifically revered as the deity of hospitality, customs, and the guardian of compacts and marriages. In the Rig Veda, he is frequently invoked during marriage ceremonies to bless the union and ensure the stability of the social bond. While Mitra is primarily the god of contracts and friendship, and Varuna is the guardian of the cosmic order (Rta), Aryaman's role focuses on the formalization of social ties and the institution of marriage. Marut refers to the storm deities who are companions of Indra, and Agni is the god of fire and the messenger between humans and the divine.
