Referral Chain

A referral chain is the complete hierarchy of partner relationships that connects an end customer back to the original referring affiliate. In a multi-tier commission structure, each link in the chain represents a partner who recruited the next, and each earns an override commission or percentage on the activity generated downstream. A simple two-tier chain has an affiliate and a sub-affiliate; more complex structures -- common in Forex IB networks -- can extend to three, four, or more levels with a master IB at the top.

Accurate referral chain tracking is essential for correct commission calculation. When a customer converts, the platform must traverse the full chain to determine who earns what. Each level typically receives a smaller share: the direct referrer earns the standard commission, their recruiter earns a tier-2 override, and so on up the hierarchy. Errors in chain attribution -- such as broken links, circular references, or unresolved parent assignments -- can cause commission disputes and erode partner trust.

Referral chains also play a role in fraud detection. Unusually deep chains, chains where the same entity appears at multiple levels, or chains where all downstream activity originates from a single traffic source can signal self-referral schemes or artificially inflated sub-affiliate networks. Operators who monitor chain structure alongside conversion quality can identify problematic patterns before they result in significant payouts.

From a programme design perspective, operators must decide the maximum chain depth their programme supports. Deeper chains offer more recruitment incentive but increase calculation complexity and reduce the commission available at each level. Most programmes cap at two or three tiers to balance growth incentives with operational simplicity and sustainable commission waterfall economics.
