Hello I wanted to swap eth but loopring (https://loopring.org/) didn’t see my eth. I changed the layer from 1 to 2. as someone adviced me. I swaped around $300 in eth and got only 22 in layer 2. Did I just pay 280 for gas? If not How can I send all of it??? How can I get back to layer 1??? I have so many coins there. Pls help. Metamask is way too complicated,

If you have an issue with your swap conducted on LoopRing, you will need to contact their support for assistance.
You can search for the txid on etherscan.io to see details of the swap and what exactly happened with your tokens.
