On the web of SDC i've read: "The ShadowCash team have stopped working on the Shadow Project. They are now working on a new and improved project called Particl". Someday soon we read: "The Particl team have stopped working on the Particl Project. They are now working on a new and improved project called ShitCoin".
You have to ask Dadon. My friend Zemmer, which he ows quite some money, told me he is a master of deceivery. Just remember that everything he tells is BS, in fact I thinking he is from the other side (preference wise). Now regarding the swap.
It did happen and looking at the state of blocktix we will see Rhyno do more updates now.
Some of the particl team did feel it was gig time and left particl. but with the hacks happening expect them working again on part again.
The current wallet is a joke (yes they worked months on a bitcoin wallet, replacing icons and stuff).
