This week, the Goldman Sachs-backed Circle announced that the firm would be introducing four new cryptocurrency tokens to its Circle Invest platform. Circle is adding cross-border payment solution Stellar, decentralized exchange-powering 0x, hybrid blockchain QTUM, and “the most powerful infrastructure for decentralized applications,” EOS.

The new assets are both available individually for investors to buy and trade, and as part of Circle’s unique “Buy the Market” feature that lets users buy into a crypto index-like fund that includes other top cryptocurrencies offered by the company.

The assets were chosen using the Circle Asset Framework, based on “their potential to contribute powerful infrastructure to the broader crypto ecosystem.”

In addition to the newly added cryptocurrency assets, Circle is rolling out its new “Explore” feature aimed at educating investors on the assets they are potentially investing in. In a blog post, a representative for Circle explained:

“We see an opportunity to shed light on the goals of each crypto project, the role of the crypto asset within the project and on what gives each crypto asset value. We are taking the first step in this direction through the introduction of “Explore”, a new feature in Circle Invest that will give contextual, relevant information on the various aspects of crypto. Accompanied with our simple user experience, this easy to understand content will serve to further our mission of bringing crypto mainstream.”

With this new update, Circle now offers a total of 11 crypto assets, including Bitcoin, Ethereum Bitcoin Cash, Ethereum Classic, Litecoin, Zcash, Monero, and the newly listed Stellar, 0x, QTUM, and EOS.

Back in February of this year, Circle acquired the popular cryptocurrency exchange Poloniex. Circle was also among the cryptocurrency organizations forming the newly created lobbying group, the Blockchain Association.
