The Kin blockchain is built to scale for mass usage and supports an Ecosystem-wide digital economy where app developers and mainstream consumers make millions of micro-transactions. App developers anywhere can seamlessly integrate the Kin SDK into their platform and become active partners in the Ecosystem’s growth. When developers join the Kin Ecosystem, they benefit from the Kin Rewards Engine (KRE). The KRE incentivizes app developers to create engaging user experiences and pays them when users spend Kin within their apps.
