A peer-to-peer marketplace for rare digital items and crypto collectables has acquired Atomic Bazaar, an Ethereum digital asset platform focused on trading mixed sets of non-fungible tokens (NFTs).

OpenSea, which enables users to buy, sell, and discover rare digital items, is adding Atomic Bazaar to its marketplace. Founded in November 2017, OpenSea has over 50 categories and more than 1.2 million items listed. Using interoperable standards such as ERC721, the team behind OpenSea are, according to the company, “building tools that allow any developer to build rich, integrated marketplaces for their digital assets.”

In an announcement from the platform, OpenSea said that they were “impressed” with Atomic Bazaar when it launched in July, adding:

“The Atomic Bazaar experience brought something entirely new to the NFT ecosystem by focusing on bartering: on Atomic Bazaar, users can organise real-time trades for mixed sets of NFTs. The site became very popular with the CryptoStrikers community, since trading is one of the most important components of card games.”

OpenSea have added support for eBay-style bidding, bundling, and auctioning in other currencies. However, the marketplace notes that this is just the beginning. It goes on to state that with the acquisition of Atomic Bazaar, it will be adding new ways to exchange, “including item-to-item bartering, more sophisticated orders, and much more.”

“We think these will drive greater liquidity of blockchain-based assets and truly allow this ecosystem to flourish,” the team added.

Some of the team members of OpenSea include Jordan Messina and Dan Viau from Atomic Bazaar, who launched KittyHats, following the launch of CryptoKitties. KittyHats is a platform that allows users to accessorise their CryptoKitties with hats and apparel.

According to OpenSea, KittyHats was the “first experiment” in layer two gaming experiences on the Ethereum network, and as such demonstrated what was unique about the technology behind it.
