Optimistic Ethereum (OE) is a Layer 2 scaling protocol for Ethereum applications. I.e., it makes transactions cheap. Real cheap. We aim to make transacting on Ethereum affordable and accessible to anyone. Optimistic Ethereum is meant to look, feel and behave like Ethereum but cheaper and faster. Generally speaking, you should be able to use Optimistic Ethereum with any wallet that allows you to manually connect to other EVM-compatible chains. EVM stand for Ethereum Virtual Machine. The easiest way to move assets between Layer 1 and Layer 2 is to use the Optimism Gateway.

Note that in Optimistic Ethereum, there is no ETH as we know it. Instead, gas costs are charged using a wrapped ETH ERC-20 token. When you deposit ETH into Optimistic Ethereum, those ERC-20 tokens are what you get on L2. On withdrawal times

While communication from Layer 1 to Layer 2 only takes a few minutes, communication from Layer 2 to Layer 1 on the Optimistic Ethereum mainnet takes about a week. This is a security measure that leaves enough time for invalid transaction results to be caught and reverted before they become "finalized." This means that you must wait one week before you can claim a withdrawal on the Optimistic Ethereum mainnet.
