Ethereum

Hello All,

Have been using defi (Oasis, Defi Saver, Avve, Uniswap, etc) on the ethereum mainnet for as long as I can remember.

Getting tired of the high gas prices. Thinking of using metamask to bridge to optimism which is integrated which is integrated with most of the Dapps I am using.

This is my first time using Layer2s. Was always concerned with centralization and safety but transaction costs on the mainnet are brutal and will probably only get worse if we see a new bull run.

How secure/safe is optimism? What is the best/safest ways to bridge assets back and forth. Is there a better way to accomplish what I am trying to do?

Thanks in advance for the help!
