I’m not sure if what you shared has any connection to the Splash incident, but several swap exchanges have been undergoing maintenance recently, at least from what I’ve seen. It doesn’t necessarily mean it’s the same attack, but the coincidence struck me as odd.
We cannot expect that such matters will be brought to the public eye too much.
I don't know if Splash is contacting anyone (or perhaps the so-called white hat).
Unfortunately, cases like this, especially involving hacks in instant exchanges, usually have no consequences, because the guy could literally be on the other side of the world. I just hope Splash stays strong to continue in this market, not everything is the end, because they still have the site active (although under maintenance, a red message appears when you simulate a swap)...
Well, the thing is to wait for their statement.
