How does the gateway works regarding to the traceability of the Blockchain?
For example: I send ETH to my Waves wallet. ETH will "change" as wETH. Now I trade wETH to Monero (Does it called wXMR?). Then I withdraw wXMR to my desktop Monero wallet. Are all these steps traceable or is it anonymous?
Some of transaction traceable for example you can find information about DEX's exchanges operations.
But if you withdraw coins like BTC or Monero you send it to gateway address. In such transaction there is an attachment with encripted output address. In bitcoin blockchain teorethically you can try to find transaction with the same amount in transaction made in a specific period, but it is not possible with monero.
