It seems that Tornado Cash (https://tornado.cash/) could have been used to launder the funds. I wonder if:

- Laundering happened before Tornado Cash existed, so Tornado Cash was not used

- They used something like Tornado Cash, but the funds were still traceable

Another possibility is Ironfish(https://ironfish.network/), but I don't know how much liquidity there exists in either of these. I don't think you could launder/hide $4bn through either of these. Perhaps slowly over a long period of time.
