BTC.com, a Bitcoin wallet owned by Chinese Bitcoin firm Bitmain Technologies, has announced a new partnership with US-based cryptocurrency exchange platform Kraken to offer an in-wallet buying option.

Bitcoin purchases will be handled by Kraken Direct, formerly known as Glidera, a service Kraken acquired in December 2016. Kraken Direct allows for one-click purchases and sales of bitcoins directly from users’ wallets.

A new “Buy” option will be made available to users in the BTC.com wallet app. The company plans to expand bitcoin purchasing capabilities beyond the US later this year.

“Our users will be thrilled to know that they no longer need to leave our wallet to purchase bitcoin,” said BTC.com’s business development and marketing manager Alejandro De La Torre. “Purchases can now be made directly in the BTC.com wallet. We are also delighted to partner with Kraken Direct, an industry leader with a highly professional service and team.”

In July 2016, Blocktrail, a startup that provided a Bitcoin mobile wallet, an API, a developers platform and a popular blockchain explorer was acquired by Bitmain, which rebranded the service to BTC.com.

Bitmain is a leading firm in the cryptocurrency space that operates several brands and platforms including Antminer, Antpool and Hashnet. The company is one of the world’s leading manufacturers of Bitcoin mining hardware.

Digital currency wallet providers have recently begun offering in-wallet cryptocurrency buying options as they seek to provide greater convenience and more features to customers.

Last year, Jaxx, a multi cryptocurrency wallet developed by Canadian startup Decentral, announced a partnership with ShapeShift to add an in-wallet cryptocurrency conversion feature.

ShapeShift is a company based in Switzerland that offers global trading of a variety of digital assets via web and mobile platforms. The service focuses on speed, convenience and security.
