In case you have missed it, BarterDex is near release. It is a full exchange based on Atomic Swaps. In fact it is the most advanced Atomic Swaps solution available now.

http://coremedia.info/blockchain-news/item/836-barterdex-atomic-swaps-made-easy

It includes the following features:

• Realtime orderbooks
• Update your prices in realtime
• Liquidity multiplier: you can place multiple orders with the same funds, when any gets filled the others get cancelled
• Electrum lite mode: no need to download the full blockchains of the coins you trade
• Variable confirmations preference setting: from zeroconf (25-30 seconds per trade but less secure) up to full notarization on Bitcoin blockchain
• Portfolio api: set percentage of coins you want and it automatically trades towards that goal
• Easy to use GUI (in development)

Among the coins supported (or soon to be), are: Bitcoin, Litecoin, Dash, Zcash, Stratis, Komodo, PIVX, Vertcoin, Dogecoin and 80+ other coins, including Komodo's assetchains and fiat pegs... more will be added as soon as they update their code to include Cltv & gettxout or their equivalent
