Kin is a cryptocurrency initially launched by Kik Interactive, the company behind the social messaging app Kik, in September 2017. Designed to foster a user-friendly digital ecosystem, Kin aims to revolutionise the way value is exchanged over the internet by incentivising user engagement and rewarding content creators. It was originally built on the Ethereum blockchain as an ERC-20 token but transitioned to the Solana blockchain to enhance scalability and transaction speed. Kin's principal objective is to create a decentralised ecosystem that empowers users with unique earning and spending opportunities within an array of mobile and web applications. It is characterised by its focus on easy integration for developers, low transaction costs, and immediate transaction finality, making it a convenient and efficient digital currency for microtransactions.
