Haven is built on the Open Bazaar protocol:
Haven creates a mobile window into the groundbreaking OpenBazaar network powered by cryptocurrencies like Bitcoin, Bitcoin Cash, Litecoin and Zcash (Ethereum coming soon). Over 250,000 nodes have been created by people using this peer-to-peer network since the release of version 2.0 and tens of thousands of listings have been put up for sale from crypto tokens to original paintings by popular artists to business services. OB1 expects Haven to rapidly bring even more users onto the network who are eager to shop, chat and send cryptocurrencies privately from their mobile phones.
