Messaging app Kik's users can now begin earning and spending the cryptocurrency kin with the launch of its "crypto-economy," the company announced Wednesday.

According to Kik, a limited number of users will be able to earn kin tokens in the Kin Marketplace Beta by taking quizzes, working on tutorials and answering polls, according to a press release. These tokens can, in turn, be used to purchase premium themes for the Kik app.

Kik is also rolling out free customization tools, including themes, for the app in response to user feedback, the company announced.

Product manager Laura Newton wrote in a release that Kik "wanted to build Kin into [the] products that people already use on a daily basis." As such, custom options for its app felt like "the perfect option" given the demand.

She went on to say:

The marketplace will feature the first transaction run on kin's blockchain, she said. Users included in the test can access the marketplace through the app.

Kin notably operates on its own blockchain, which it forked off the stellar mainnet earlier this year. The Kin Foundation announced it would be able to offer zero-fee transactions by using its own unique network, the company told CoinDesk.

That move came just months after Kin announced it would be running on both the ethereum network, on which it was originally built, and the stellar network, where it planned to move to late last year.
