Methods and systems for establishing a chain of relationships are disclosed. An identity verification platform receives a first request for registration comprising an identification of a first user, identification of an entity, and a relationship between the first user and the entity; verifies the identity of the first user and the relationship between the first user and the entity; and verifies that the entity is legitimate. Once a relationship between a first individual, invited by the first user, and the entity is confirmed, the platform creates a custom badge representing the relationship between the first individual and the entity for display on the entity's website. The platform receives an identification of a selection by an end user of the custom badge and, responsive to receiving the identification of the selection, renders, on a domain controlled by the identity verification platform, a verification that the relationship between the first individual and the entity is valid.
