Yep, the PalmPay point of sale system (palmpay.io) is adding atomic swaps and payment channels on interledger protocol as we speak. This means that merchants won't have to rely on centralised exchanges or bridges anymore either, and of course the Bitcoin Lightning Network will be natively supported (amongst many others) as well.

As for the BTCLN:BTS token, a smartcoin/mpa would be great for that too, someone just needs to create it and get its liquidity moving so a market can form around that pair.

Atomic Swaps are the future. Byebye CEX's. :)
