Let's talk about Layer 2 networks.
Layer 2 refers to scaling networks built on top of the Ethereum mainnet. Transactions are processed on Layer 2, and then the data is submitted to the mainnet.
One thing many people overlook: Layer 2 can be cheap because a large number of transactions are bundled together and submitted to the mainnet, with the mainnet fees shared among those transactions.
When transferring funds, make sure to check which network you've selected: assets at the same address are separate on different networks.
