Twitter will allow users to send and receive “tips” using bitcoin as part of a broader campaign to help users make money from the service.

Twitter said Thursday that it is looking into authenticating users’ non-fungible tokens (NFTs), which are digital goods ranging from high-quality artwork to images of “digital monkeys.” Some users already display non-fungible tokens in their profiles. But there is no easy way to believe if the person viewing the photo actually owns it.

Esther Crawford, executive director of products that build features for creators at Twitter, said, “Creators have a growing interest in using apps that run on the blockchain. We want to help them share in the promise of an evolving, decentralized internet directly on Twitter.”

In addition, the updates are part of Twitter’s strategy to attract creators by giving them more ways to share their work through the service, and more ways to earn money. Twitter had introduced the tip feature for several months, but it was working under the limited testing framework.
