# CPA Pool CPA Pool (Cost Per Action) is XOOB’s performance-based reward layer. It allows campaigns to reward creators not only for generating attention, but also for verified actions performed by users they bring into the ecosystem. In CPA-enabled campaigns, projects allocate a portion of their campaign budget into a pool that distributes rewards based on measurable outcomes generated by creators. ### What counts as a “CPA action” CPA actions are defined by the project and can include events such as: * on-chain transactions * deposits or liquidity actions * protocol interactions * registrations or product usage events * repeat activity and ongoing engagement These actions represent real product adoption rather than social attention. ### Reward distribution When a user performs a verified action that can be attributed to a creator’s influence, the corresponding reward is distributed from the CPA Pool. Rewards are delivered directly to the creator’s wallet, allowing creators to receive performance incentives without intermediaries. ### Relationship with ImpactShare CPA Pool operates as an additional reward layer on top of ImpactShare. ImpactShare measures the influence and contribution of creators within the campaign, while CPA Pool rewards verified product actions generated by that influence. This structure allows campaigns to recognize both: * creators who drive meaningful discussions and attention * creators whose audience converts into real users Strong performance in CPA-enabled campaigns can reinforce the creator’s overall contribution within the campaign ecosystem, aligning influence with measurable outcomes. ### From attention to adoption By combining ImpactShare with CPA-based rewards, XOOB campaigns move beyond attention metrics and toward verifiable product growth. Creators are rewarded not only for being heard, but for bringing users who actively interact with the product. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
