I recently learned that there is a convenient service for transferring coins between networks. https://defiway.com/bridges/ has a collection of different bridges that allow you to quickly transfer Ether and other tokens. I used to think that this required complex schemes or third-party sites, but here everything is collected in one place. The interface is simple: connect your wallet, select the network and amount, and you're done. I tested it with a small transaction, and the money arrived quickly and without any problems.
