As a base layer blockchain, applications and money lego primitives can be built on top of Umee to access cross chain leverage and liquidity. We believe that Umee and Osmosis can complement each other to offer a superior DeFi experience for users of the Cosmos ecosystem.\n\nWebsite: https://www.umee.cc/\nTwitter: https://twitter.com/Umee_CrossChain\nDiscord: https://discord.gg/umee
