Atlantis was a darknet market founded in March 2013, the third such type of market, concurrent with The Silk Road and Black Market Reloaded.
In July 2013 its startup style video attracted much media attention.
It was the first market to accept Litecoin.
Shortly after Operation Onymous, the market closed with one week's notice in September 2013, in what was believed by some site staff to be outright theft.
